Accounting Policies [Abstract]
Accounting Policies	ACCOUNTING POLICIES Basis of Presentation The unaudited condensed consolidated financial statements (“financial statements”) include the accounts of Glatfelter and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. We prepared these financial statements in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial statements. In our opinion, the financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. When preparing these financial statements, we have assumed you have read the audited consolidated financial statements included in our 2021 Annual Report on Form 10-K. Discontinued Operations The results of operations and cash flows of our former Specialty Papers business have been classified as discontinued operations for all periods presented in the condensed consolidated statements of income. Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Management believes the estimates and assumptions used in the preparation of these financial statements are reasonable, based upon currently available facts and known circumstances, but recognizes actual results may differ from those estimates and assumptions. Inventories Our inventories are stated at the lower of cost or net realizable value. Raw materials, in-process and finished goods inventories are valued principally using the average-cost method.

Goodwill and Other Asset Impairment	Sep. 30, 2022
Asset Impairment Charges [Abstract]
Goodwill and Other Asset Impairment	GOODWILL AND OTHER ASSET IMPAIRMENT During the third quarter of 2022, we recognized a non-cash goodwill impairment charge for our Spunlace segment of $42.5 million. The Spunlace segment has faced continued inflationary challenges which had escalated since our acquisition of this business in late 2021. Our selling price increases have been insufficient to offset the impact of inflation. Furthermore, the Spunlace segment has been impacted by unexpected supply chain and other operational issues which, in combination with the commercial issues, have resulted in an unexpected increase in operating losses. Although, management expects it will address the commercial, as well as, operational challenges that have impacted the profitability of this segment, the timing to effectuate the necessary changes to improve performance of this segment will be longer than previously expected. As a result of these changes, the Company performed a goodwill assessment this quarter which has prompted the impairment charge. In the first quarter of 2022, in connection with an assessment of potential impairment of long-lived and indefinite lived intangible assets stemming from the compounding impacts resulting from the Russia/Ukraine military conflict and related sanctions, we recorded a $117.3 million non-cash asset impairment charge related to Composite Fibers' Dresden facility and an impairment of Composite Fibers' goodwill. Dresden is a single-line facility that produces wallcover base paper, the majority of which is sold into the Russian and Ukrainian markets. As a direct result of the economic impacts from the conflict, and the disruptions in the underlying financial systems and prohibition of the export of sanctioned wallcover base paper to Russia, management expects a significant reduction in wallcover revenues and associated cash flows for the foreseeable future. In addition, the conflict is expected to significantly impact energy prices and also impact other Composite Fibers products that are also subject to export sanctions into Russia. Accordingly, a charge was recorded to reduce the carrying value of the Dresden fixed assets and intangible assets (technological know-how, customer relationships, and an indefinite-lived trade name), along with Composite Fibers’ goodwill to fair value. The following table summarizes the impairment charges recorded in the accompanying condensed consolidated statements of income under the caption “Goodwill and other asset impairment charges:” In thousands Three months ended September 30, Nine months ended September 30, Machinery and equipment $ — $ 27,619 Technological know-how — 18,443 Customer relationships — 11,695 Tradename — 3,530 Goodwill 42,541 98,603 Total $ 42,541 $ 159,890 The fair value of the underlying assets was estimated using discounted cash flow models, independent appraisals and similar methods, all of which are Level 3 fair value classification. As a result of economic sanctions and disruptions to the financial markets, certain Russian and Ukrainian customers are not able to satisfy outstanding accounts receivables. As such, during the first nine months of 2022, we recognized bad debt expense of approximately $2.9 million directly related to Russian and Ukrainian customers. Furthermore, during the first nine months of 2022, we increased inventory reserves by approximately $1.0 million, primarily related to wallcover products.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION On May 5, 2022, upon Board and shareholder approval, the Glatfelter Corporation 2022 Long-Term Incentive Plan became effective and is a successor plan to the P. H. Glatfelter Amended and Restated Long-Term Incentive Plan (collectively, the “LTIP”). The LTIP continues to provide for the issuance of Glatfelter common stock to eligible participants in the form of restricted stock units, restricted stock awards, non-qualified stock options, performance shares, incentive stock options and performance units. Furthermore, the LTIP increases the number shares previously available for issuance by 1,400,000 shares. As of September 30, 2022, there were 2,456,410 shares of common stock available for future issuance under the LTIP. Pursuant to terms of the LTIP, we have issued to eligible participants restricted stock units (“RSUs”), performance share awards (“PSAs”) and stock-only stock appreciation rights. In 2022, we issued awards to employees of RSUs and PSAs under our LTIP. In 2022, 50% of fair value of the awards granted were RSUs, which vest based on the passage of time, generally over a graded three-year period or, in certain instances, the RSUs were cliff vesting after one During the three months ended September 30, 2022, we issued 360,000 PSAs and 240,000 RSUs to our new CEO, Thomas Fahnemann, as part of his on-boarding compensation package. These PSAs have a 3-year service and performance requirement that is based on our stock price achieving certain levels during the performance period. Specifically, if the Company’s closing stock price is $10 or higher for 20 consecutive days during the performance period, 50% of the award is achieved. If the stock price exceeds $18 per share for 20 consecutive days during the performance period 100% of the award is achieved. The RSUs vest over a three-year period with 50% vesting after two years and the remainder vesting after three years. During the three months ended September 30, 2022, in connection with his separation from the Company, certain unvested RSUs and PSAs of the former CEO were forfeited, and as a result, the Company recognized a stock-based compensation benefit of approximately $3.1 million which is included in Selling, general and administrative expense on the accompanying condensed consolidated statements of income. For RSUs, the grant date fair value of the awards, or the closing price per common share on the date of the award, is used to determine the amount of expense to be recognized over the applicable service period. For PSAs, the grant date fair value is estimated using a lattice model. The significant inputs include the stock price, volatility, dividend yield, and risk-free rate of return. Settlement of RSUs and PSAs will be made in shares of our common stock currently held in treasury.

Income Taxes

Income Taxes	Sep. 30, 2022
Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Income taxes are recognized for the amount of taxes payable or refundable for the current year, and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our condensed consolidated financial statements or tax returns. The effects of income taxes are measured based on enacted tax laws and rates. For the nine months ended September 30, 2022, we had a pretax loss from continuing operations of $168.6 million and income tax benefit of $8.6 million. The income tax benefit includes $19.7 million of deferred tax benefit associated with the asset impairment charges and related bad debt and inventory reserves (refer to Note 6). Absent these charges, the Company had a pre-tax loss of $4.7 million and income tax expense of $11.1 million, which was unfavorably impacted by the jurisdictional mix of pretax results among the Company and its subsidiaries, and certain domestic and foreign jurisdiction losses which generated no tax benefit. The effective tax rate for the third quarter of 2022 was negatively impacted by recording a valuation allowance on the net operating losses related to Spunlace operations in Soultz, France. The impact of that valuation allowance was an increase in tax expense of $5.3 million. For the nine months ended September 30, 2022, we recorded an increase in the valuation allowance of $12.0 million for U.S. federal and foreign jurisdictions against our net deferred tax assets. In assessing the need for a valuation allowance, management considers all available positive and negative evidence in its analysis. Based on this analysis, we recorded a valuation allowance for the portion of deferred tax assets where the weight of the evidence indicated it is more likely than not that the deferred assets will not be realized. As of September 30, 2022 and December 31, 2021, we had $56.4 million and $55.7 million, respectively, of gross unrecognized tax benefits. As of September 30, 2022, if such benefits were to be recognized, approximately $52.5 million would be recorded as a component of income tax expense, thereby affecting our effective tax rate. The amount of income taxes we pay is subject to ongoing audits by federal, state and foreign tax authorities, which often result in proposed assessments. Management performs a comprehensive review of its global tax positions on a quarterly basis and accrues amounts for uncertain tax positions. Based on these reviews and the result of discussions and resolutions of matters with tax authorities and the closure of tax years subject to tax audit, reserves are adjusted as necessary. However, future results may include favorable or unfavorable adjustments to our estimated tax liabilities in the period the assessments are determined or resolved or as statutes are closed. Due to potential resolution of federal, state and foreign examinations, and the lapse of various statutes of limitation, it is reasonably possible our gross unrecognized tax benefits may decrease within the next twelve months by a range of zero to $1.9 million. We recognize interest and penalties related to uncertain tax positions as income tax expense. The following table summarizes information included in continuing operations related to interest on uncertain tax positions: Nine months ended September 30, In millions 2022 2021 Interest expense $ 0.5 $ 0.4 September 30, December 31, Accrued interest payable $ 4.4 $ 3.9 Accrued penalties 3.0 3.0

Leases [Abstract]
Leases	LEASES We enter into a variety of arrangements in which we are the lessee for the use of automobiles, forklifts and other production equipment, production facilities, warehouses, office space and land. We determine if an arrangement contains a lease at inception. All our lease arrangements are operating leases and are recorded in the condensed consolidated balance sheet under the caption “Other assets” and the lease obligation is under “Other current liabilities” and “Other long-term liabilities.” We do not have any finance leases. Operating lease right of use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. ROU assets also include any initial direct costs incurred and any lease payments made at or before the lease commencement date, less lease incentives received. We use our incremental borrowing rate based on information available at the commencement date in determining the lease liabilities as our leases generally do not provide an implicit rate. For purposes of recording the lease arrangement, the term of lease may include options to extend or terminate when we are reasonably certain that the option will be exercised. Lease expense is recognized on a straight-line basis over the lease term. The following table sets forth information related to our leases as of the periods indicated.

On May 9, 2022, we entered into an amendment to the Credit Agreement. The amendment: i) increases the permitted maximum ratio of consolidated total net debt to consolidated adjusted EBITDA (“leverage ratio”); ii) increases the maximum interest rate borrowing margin to be applied to the applicable index by 25 basis points; and iii) pledges as collateral substantially all domestic assets to secure obligations owed under the Credit Agreement. As amended, we are obligated to maintain a maximum ratio of consolidated total net debt to consolidated adjusted EBITDA of 6.75 to 1.0 until the quarter ended December 31, 2023, after which the maximum leverage ratio steps down to 4.0 to 1.0. The Credit Agreement also contains covenants requiring a minimum interest coverage ratio and provisions limiting our ability to, among other things, (i) incur debt and guaranty obligations, (ii) incur liens, (iii) make loans, advances, investments and acquisitions, (iv) merge or liquidate, (v) sell or transfer assets, (vi) incur additional indebtedness. As of September 30, 2022, the leverage ratio calculated in accordance with the definition in our Credit Agreement was 5.7x . A breach of these requirements would give rise to certain remedies under the Revolving Credit Agreement, among which are the termination of the agreement and the repayment of the outstanding borrowings plus accrued and unpaid interest under the Credit Agreement. Glatfelter Corporation guarantees all debt obligations of its subsidiaries. All such obligations are recorded in these condensed consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Derivatives and Hedging Activities	FINANCIAL DERIVATIVES AND HEDGING ACTIVITIES As part of our overall risk management practices, we enter into financial derivatives primarily designed to either i) hedge foreign currency risks associated with forecasted transactions (“cash flow hedges”); ii) mitigate the impact that changes in currency exchange rates have on intercompany financing transactions and foreign currency denominated receivables and payables (“foreign currency hedges”); or iii) convert variable-interest-rate debt to fixed rates. Derivatives Designated as Hedging Instruments - Cash Flow Hedges We use currency forward contracts as cash flow hedges to manage our exposure to fluctuations in the currency exchange rates on certain forecasted production costs. Currency forward contracts involve fixing the exchange for delivery of a specified amount of foreign currency on a specified date. As of September 30, 2022, the maturity of currency forward contracts ranged from one month to 18 months. We designate certain currency forward contracts as cash flow hedges of forecasted raw material purchases, certain production costs or capital expenditures with exposure to changes in foreign currency exchange rates. Changes in the fair value of derivatives designated and that qualify as cash flow hedges of foreign exchange risk is deferred as a component of accumulated other comprehensive income in the accompanying condensed consolidated balance sheets. With respect to hedges of forecasted raw material purchases or production costs, the amount deferred is subsequently reclassified into costs of products sold in the period that, inventory produced using the hedged transaction, affects earnings. For hedged capital expenditures, deferred gains or losses are reclassified and included in the historical cost of the capital asset and subsequently affect earnings as depreciation is recognized. We had the following outstanding derivatives that were used to hedge foreign exchange risks associated with forecasted transactions and designated as hedging instruments: In thousands September 30, 2022 December 31, 2021 Derivative Sell/Buy - sell notional Euro / British Pound 22,203 18,823 U.S. Dollar / British Pound 28,754 16,205 U.S. Dollar / Euro 1,911 658 Sell/Buy - buy notional Euro / Philippine Peso 964,410 896,291 British Pound / Philippine Peso 1,301,671 1,121,183 Euro / U.S. Dollar 96,822 108,467 U.S. Dollar / Canadian Dollar 36,649 36,904 On June 15, 2022, we terminated a €180 million notional value floating-to-fixed interest rate swap agreement with certain financial institutions that was entered into in October 2019 and was to mature in December 2022. During the life of the swap, we paid a fixed interest rate of the applicable margin plus 0.0395% on €180 million of the underlying variable rate term loan. We received the greater of 0.00% or EURIBOR. At termination, we recognized a deferred gain of $0.4 million that will be amortized into interest expense through December 2022. Derivatives Designated as Hedging Instruments – Net Investment Hedge The €220 million Term Loan discussed in Note 16 – “ Long-Term Debt” is designated as a net investment hedge of our Euro functional currency foreign subsidiaries. During the first nine months of 2022 and 2021, we recognized a pre-tax gain of $27.5 million and $13.8 million, respectively, on the remeasurement of the term loan from changes in currency exchange rates. Such amounts are recorded as a component of Other Comprehensive Income (Loss). On September 6, 2022, we terminated a $150.0 million cross currency swap agreement with certain financial institutions that was entered into in March 2022 and was to mature in May 2025. Pursuant to the terms of the swap, we agreed to receive 4.750% interest denominated in U.S. dollars and we agreed to pay 3.06% interest denominated in euros. We designated the cross-currency swap as a hedge of our net investment in certain euro functional currency subsidiaries. We collected cash proceeds of approximately $15.2 million upon termination. The gain associated with the swap remains in accumulated other comprehensive loss. Derivatives Not Designated as Hedging Instruments - Foreign Currency Hedges We also entered into forward foreign exchange contracts to mitigate the impact changes in currency exchange rates have on balance sheet monetary assets and liabilities. None of these contracts are designated as hedges for financial accounting purposes and, accordingly, changes in value of the foreign exchange forward contracts and in the offsetting underlying on-balance-sheet transactions are reflected in the accompanying condensed consolidated statements of income under the caption “Other, net.” The following sets forth derivatives used to mitigate the impact changes in currency exchange rates have on balance sheet monetary assets and liabilities: In thousands September 30, 2022 December 31, 2021 Derivative Sell/Buy - sell notional U.S. Dollar / British Pound 29,200 26,600 British Pound / Euro 3,200 3,400 U.S. Dollar / Swiss Franc 430 2,180 British Pound / Swiss Franc 2,420 1,025 Euro / Swiss Franc 7,830 2,750 Euro / U.S. Dollar 7,200 11,000 Sell/Buy - buy notional Euro / U.S. Dollar 6,300 20,900 British Pound / Euro 17,800 5,300 These contracts have maturities of one month from the date originally entered into. Fair Value Measurements The following table summarizes the fair values of derivative instruments for the period indicated and the line items in the accompanying condensed consolidated balance sheets where the instruments are recorded: In thousands September 30, 2022 December 31, 2021 September 30, 2022 December 31, 2021 Balance sheet caption Prepaid Expenses and Other Other Designated as hedging: Forward foreign currency exchange contracts $ 9,573 $ 3,197 $ 4,685 $ 288 Interest rate swap — — — 44 Not designated as hedging: Forward foreign currency exchange contracts $ 1,070 701 $ 1,458 $ 116 The amounts set forth in the table above represent the net asset or liability giving effect to rights of offset with each counterparty. The effect of netting the amounts presented above did not have a material effect on our consolidated financial position. The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The fair values of the foreign exchange forward contracts are considered to be Level 2. Foreign currency forward contracts are valued using foreign currency forward and interest rate curves. The fair value of each contract is determined by comparing the contract rate to the forward rate and discounting to present value. Contracts in a gain position are recorded in the condensed consolidated balance sheets under the caption “Prepaid expenses and other current assets” and the value of contracts in a loss position is recorded under the caption “Other current liabilities.” The following table summarizes the amount of income or (loss) from derivative instruments recognized in our results of operations for the periods indicated and the line items in the accompanying condensed consolidated statements of income where the results are recorded: Three months ended Nine months ended September 30, In thousands 2022 2021 2022 2021 Designated as hedging: Forward foreign currency exchange contracts: Cost of products sold $ (2,275) $ 67 $ (5,044) $ 10 Interest expense (173) 21 (162) 64 Not designated as hedging: Forward foreign currency exchange contracts: Other – net $ 1,253 $ (376) $ 2,982 $ 327 The impact of activity not designated as hedging was substantially all offset by the remeasurement of the underlying on-balance-sheet item. A rollforward of fair value amounts recorded as a component of accumulated other comprehensive income (loss), before taxes, is as follows: In thousands 2022 2021 Balance at January 1, $ 2,889 $ (3,460) Deferred gains on cash flow hedges 9,578 4,920 Reclassified to earnings (5,206) (74) Balance at September 30, $ 7,261 $ 1,386 We expect substantially all of the amounts recorded as a component of accumulated other comprehensive income will be recorded in results of operations within the next 12 to 18 months and the amount ultimately recognized will vary depending on actual market rates. Credit risk related to derivative activity arises in the event the counterparty fails to meet its obligations to us. This exposure is generally limited to the amounts, if any, by which the counterparty’s obligations exceed our obligation to them. Our policy is to enter into contracts only with financial institutions which meet certain minimum credit ratings.

Commitments, Contingencies and Legal Proceedings	COMMITMENTS, CONTINGENCIES AND LEGAL PROCEEDINGS Fox River - Neenah, Wisconsin Background We have previously reported that we face liabilities associated with environmental claims arising out of the presence of polychlorinated biphenyls (“PCBs”) in sediments in the lower Fox River, on which our former Neenah facility was located, and in the Bay of Green Bay, Wisconsin (collectively, the “Site”). Since the early 1990s, the United States, the State of Wisconsin and two Indian tribes (collectively, the “Governments”) have pursued a cleanup of a 39-mile stretch of river from Little Lake Butte des Morts into Green Bay and natural resource damages (“NRDs”). The United States originally notified several entities that they were potentially responsible parties (“PRPs”); however, after giving effect to settlements reached with the Governments, the remaining PRPs exposed to continuing obligations to implement the remainder of the cleanup consist of us, Georgia-Pacific Consumer Products, L.P. (“Georgia-Pacific”) and NCR Corporation. The United States Environmental Protection Agency (“EPA”) has divided the Site into five “operable units”, including the most upstream portion of the Site on which our facility was located (“OU1”) and four downstream reaches of the river and bay (“OU2-5”). Over the past several years, we and certain other PRPs completed all remedial actions pursuant to applicable consent decrees or a Unilateral Administrative Order. In January 2019, we reached an agreement with the United States, the State of Wisconsin, and Georgia-Pacific to resolve all remaining claims among those parties. Under the Glatfelter consent decree, we are primarily responsible for long-term monitoring and maintenance in OU2-OU4a and for reimbursement of government oversight costs paid after October 2018. Finally, we remain responsible for our obligation to continue long-term monitoring and maintenance under our OU1 consent decree. Cost estimates Our remaining obligations under the OU1 consent decree consist of long-term monitoring and maintenance. Furthermore, we are primarily responsible for long-term monitoring and maintenance in OU2-OU4a over a period of at least 30 years. The monitoring activities consist of, among others, testing fish tissue, sampling water quality and sediment, and inspections of the engineered caps. In 2018, we entered into a fixed-price, 30-year agreement with a third party for the performance of all of our monitoring and maintenance obligations in OU1 through OU4a with limited exceptions, such as, for extraordinary amounts of cap maintenance or replacement. Our obligation under this agreement is included in our total reserve for the Site. We are obligated to make the regular payments under that fixed-price contract until the remaining amount due is less than the OU1 escrow account balance. We are permitted to pay for this contract using the remaining balance of the escrow account established by us and WTM I Company (“WTM I”) another PRP, under the OU1 consent decree during any period that the balance in the escrow account exceeds the amount due under our fixed-price contract. As of September 30, 2022, the balance in the escrow is less than amounts due under the fixed-price contract by approximately $1.3 million. Our obligation to pay this difference is secured by a letter of credit . At September 30, 2022, the escrow account balance totaled $8.7 million which is included in the condensed consolidated balance sheet under the caption “Other assets.” Under the consent decree, we are responsible for reimbursement of government oversight costs paid from October 2018 and later over approximately the next 30 years. We anticipate that oversight costs will decline as activities at the site have transitioned from remediation to long-term monitoring and maintenance. Reserves for the Site Our reserve for past and future government oversight costs and long-term monitoring and maintenance totaled $14.8 million at September 30, 2022, of which $2.3 million is recorded in the accompanying September 30, 2022 condensed consolidated balance sheet under the caption “Environmental liabilities” and the remaining $12.5 million is recorded under the caption “Other long-term liabilities.”

There is no comprehensive, authoritative body of guidance for management accounting equivalent to accounting principles generally accepted in the United States of America; therefore, the financial results of individual segments are not necessarily comparable with similar information for any other company. The management accounting process uses assumptions and allocations to measure performance of the segments. Methodologies are refined from time to time as management accounting practices are enhanced and businesses change. The costs incurred by support areas not directly aligned with the segment are allocated primarily based on an estimated utilization of support area services or are included in “Other and Unallocated” in the table set forth above. Management evaluates results of operations of the operating segments before certain corporate level costs and the effects of certain gains or losses not considered to be related to the core business operations.

Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements (“financial statements”) include the accounts of Glatfelter and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. We prepared these financial statements in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial statements. In our opinion, the financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. When preparing these financial statements, we have assumed you have read the audited consolidated financial statements included in our 2021 Annual Report on Form 10-K.
Discontinued Operations	Discontinued Operations The results of operations and cash flows of our former Specialty Papers business have been classified as discontinued operations for all periods presented in the condensed consolidated statements of income.
Accounting Estimates	Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Management believes the estimates and assumptions used in the preparation of these financial statements are reasonable, based upon currently available facts and known circumstances, but recognizes actual results may differ from those estimates and assumptions.
Inventories	Inventories Our inventories are stated at the lower of cost or net realizable value. Raw materials, in-process and finished goods inventories are valued principally using the average-cost method.
