Basis Of Presentation [Abstract]
Basis Of Presentation	In the opinion of management, the accompanying consolidated financial statements of Tredegar Corporation and its subsidiaries (“Tredegar,” “the Company,” “we,” “us” or “our”) contain all adjustments necessary to state fairly, in all material respects, Tredegar’s consolidated financial position as of September 30, 2020, the consolidated results of operations for the three and nine months ended September 30, 2020 and 2019, the consolidated cash flows for the nine months ended September 30, 2020 and 2019, and the consolidated changes in shareholders’ equity for the three and nine months ended September 30, 2020 and 2019, in accordance with U.S. generally accepted accounting principles (“GAAP”). All such adjustments, unless otherwise detailed in the notes to the consolidated interim financial statements, are deemed to be of a normal, recurring nature. The Company operates on a calendar fiscal year except for the Aluminum Extrusions segment, which operates on a 52/53-week fiscal year basis. As such, the fiscal third quarter for 2020 and 2019 for this segment references 13-week periods ended September 27, 2020 and September 29, 2019, respectively. The Company does not believe the impact of reporting the results of this segment as stated above is material to the consolidated financial results. The financial position data as of December 31, 2019 that is included herein was derived from the audited consolidated financial statements provided in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (“2019 Form 10-K”) but does not include all disclosures required by GAAP. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the 2019 Form 10-K. On August 24, 2020, the Company entered into a definitive agreement to sell its Personal Care Films business ("Personal Care business"), which excludes the packaging film lines and related operations located at the Pottsville, Pennsylvania manufacturing site ("Pottsville Packaging"). The Company completed this divestiture at the end of October 2020. All historical results for the Personal Care business have been presented as discontinued operations. The surface protection component of its PE Films segment now includes Pottsville Packaging. The results of operations for the three and nine months ended September 30, 2020, are not necessarily indicative of the results to be expected for the full year. Certain prior year balances have been reclassified to conform with current year presentation. Adoption of ASU 2016-13, Financial Instruments - Credit Losses In the first quarter of 2020, the Company adopted ASU 2016-13 related to the measurement of credit losses on financial instruments. The pronouncement replaces the incurred loss methodology to record credit losses with a methodology that reflects the expected credit losses for financial assets not accounted for at fair value with gains and losses recognized through net income. The adoption of the updated guidance in the first quarter of 2020 resulted in an adjustment of less than $0.2 million and, therefore, did not have a material impact on the Company’s consolidated financial statements. The Company's policy on Accounts and Other Receivables as described in the 2019 Form 10-K was revised to read as follows: Accounts and Other Receivables Accounts receivable are stated at the amount invoiced to customers less allowances for doubtful accounts and sales returns. Accounts receivable are non-interest bearing and arise from the sale of product to customers under typical industry trade terms. Notes receivable are not significant. Past due amounts are determined based on established terms and charged-off when deemed uncollectible. The allowance for doubtful accounts is determined based on an assessment of probable losses taking into account past due amounts, customer credit profile, historical experience and current economic conditions. For receivables that do not have a specific allowance, the loss rate is computed by segment to apply to the remaining receivables balance, using each segment’s historic loss rate. Other receivables include value-added taxes related to certain foreign subsidiaries and other miscellaneous receivables due within one year. For certain customers, the Company has arrangements in place with financial institutions whereby certain customer receivables are sold to the financial institution at a discount and without recourse. Upon sale, the associated receivable is unrecognized and the discount is recognized as a reduction of sales. As of September 30, 2020 and December 31, 2019, accounts receivable and other receivables, net, were $82.1 million and $89.1 million, respectively, made up of the following: September 30, December 31, (In thousands) 2020 2019 Customer receivables $ 82,369 $ 89,747 Other receivables 2,466 2,199 Total accounts and other receivables 84,835 91,946 Less: Allowance for bad debts and sales returns (2,746) (2,829) Total accounts and other receivables, net $ 82,089 $ 89,117 Risk and Uncertainties While it is not possible to estimate the impact that the coronavirus pandemic ("COVID-19") may have on the Company’s business, estimates related to the accounting for impairment of long-lived assets and goodwill, an investment accounted for under the fair value method, pension benefits and income taxes could be materially adversely affected in future periods. Due to the uncertainty with respect to the magnitude of the impact and duration of COVID-19, future developments associated with COVID-19 may adversely affect the Company's financial condition, results of operations and cash flows. The Company continues to monitor the impact of COVID-19 on the business and its effect on the consolidated financial statements.

Impairment Goodwill Impairment

Impairment Goodwill Impairment (Notes)	9 Months Ended
	Sep. 30, 2020
Goodwill Impairment Disclosure [Abstract]
Goodwill Disclosure [Text Block]	The Company assesses its long-lived assets for impairment when events and circumstances indicate that the carrying amount of the assets may not be recoverable. Long-lived assets consist primarily of buildings, machinery and equipment. During the three months ended September 30, 2020, the Company did not identify any indicators of impairment for such assets in light of the economic impacts from COVID-19 or otherwise. The Company annually assesses goodwill for impairment on December 1st of each year or more frequently when events or circumstances indicate that the carrying amount of a reporting unit that includes goodwill exceeds its fair value. The Company evaluated whether triggering events occurred for all reporting units that include goodwill and determined that triggering events did occur during the first three months of 2020 for the Aluminum Extrusions’ reporting units created as a result of acquisitions in 2012 (“AACOA”) and in 2017 (“Futura”). During the first three months of 2020, the Company performed goodwill impairment tests for the AACOA and Futura reporting units using a combination of income and market approaches and determined that the fair value of the Futura reporting unit exceeded its carrying value. As a result, the Company recognized a goodwill impairment charge of $13.7 million ($10.5 million after taxes), which represented the entire amount of goodwill associated with the AACOA reporting unit. The operations of the AACOA reporting unit, which includes the Niles, Michigan and Elkhart, Indiana facilities, was expected to be severely impacted by COVID-19, with over 80% of the aluminum extrusions manufactured at these facilities sold to customers that make consumer durable products, such as recreational boating and power sports vehicles, and to customers serving the building and construction and automotive markets. The Company evaluated whether triggering events occurred during the three months ended September 30, 2020 for all reporting units that include goodwill and determined no events or circumstances existed that indicated the fair value of the reporting units are below their carrying amounts. Recent disruptions to the global economy from COVID-19 make it reasonably possible that future impairment tests for long-lived assets and goodwill may be required during 2020. The Company continues to monitor developments and perform updated analyses as necessary.

The Company completed this divestiture at the end of October 2020. In connection with the execution of the definitive agreement and classification of the Personal Care business as discontinued operations, a non-cash impairment charge of $45.1 million was recognized during the three months ended September 30, 2020. In addition, the Company agreed to provide certain transition services related to finance, human resources and information technology. The Personal Care business was previously reported in the PE Films segment. The following table summarizes the financial results of discontinued operations reflected in the Consolidated Statements of Income for the three and nine months ended September 30, 2020 and 2019: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Revenues and other items: Sales $ 29,509 $ 37,249 $ 98,053 $ 111,920 Other income (expense), net (37) 6,362 (298) 6,332 29,472 43,611 97,755 118,252 Costs and expenses: Cost of goods sold 25,481 31,576 83,408 96,479 Freight 1,436 1,898 4,711 5,455 Selling, general and administrative 6,502 3,977 13,649 12,607 Research and development 3,138 2,933 8,451 8,926 Asset impairments and costs associated with exit and disposal activities, net of adjustments 801 1,366 1,327 2,987 Held for sale impairment loss on divested assets 45,054 — 45,054 — Total 82,412 41,750 156,600 126,454 Income (loss) from discontinued operations before income taxes (52,940) 1,861 (58,845) (8,202) Income tax expense (benefit) (4,703) (220) (5,814) (2,126) Income (loss) from discontinued operations, net of tax $ (48,237) $ 2,081 $ (53,031) $ (6,076) The assets and liabilities of the discontinued operations reflected in the Consolidated Balance Sheets as of September 30, 2020 and December 31, 2019, respectively were as follows: September 30, December 31, 2020 2019 Assets Accounts and other receivables, net $ 15,455 $ 18,441 Income tax recoverable 1,082 1,439 Inventories 15,839 17,175 Prepaid expenses and other 394 363 Total current assets (a) 37,418 Property, plant and equipment, net 57,068 69,334 Right-of-use leased assets 342 728 Deferred income taxes 679 694 Other assets 150 105 Total non-current assets (a) 70,861 Valuation allowance on assets held for sale (45,054) — Total assets of discontinued operations classified as held for sale $ 45,955 $ 108,279 Liabilities Accounts payable $ 13,844 $ 16,361 Accrued expenses 7,058 6,344 Lease liability, short-term 231 575 Income taxes payable 87 — Total current liabilities (a) 23,280 Lease liability, long-term 113 351 Deferred income taxes — — Total non-current liabilities (a) 351 Total liabilities of discontinued operations classified as held for sale (b) $ 21,333 $ 23,631 (a) The assets and liabilities of the disposal group classified as held for sale are classified as current on the September 30, 2020 Consolidated Balance Sheet as it was probable that sale of the Personal Care business would occur and proceeds would be collected within one year of September 30, 2020. (b) Pension and other postretirement benefit liabilities related to the Personal Care business have been retained by the Company. Additional information related to the amounts recognized in the discontinued operations balance sheet as of September 30, 2020 is summarized below: September 30, (In thousands) 2020 Total carrying value of assets of discontinued operations classified as held for sale before valuation allowances $ 91,009 Total liabilities of discontinued operations classified as held for sale (21,333) Carrying value of net assets of discontinued operations classified as held for sale before valuation allowances $ 69,676 Valuation allowance to reflect net assets at fair value less cost to sell (20,509) Estimated fair value less cost to sell of net assets of discontinued operations classified as held for sale $ 49,167 Valuation allowance for other comprehensive loss on foreign currency translation adjustments reflected in shareholder’s equity (“FCTA”) to be released into earnings along with the FCTA upon sale (24,545) Net assets of discontinued operations classified as held for sale reflected in the Company’s consolidated balance sheets $ 24,622 The following table provides significant operating and investing cash flow information for discontinued operations: Nine Months Ended September 30, (In thousands) 2020 2019 Operating activities Depreciation and amortization $ 6,625 $ 6,362 Held for sale impairment loss on divested assets 45,054 — Total 51,679 6,362 Investing activities Capital expenditures $ 2,989 $ 13,921 Assets Held For Sale In July 2019, the Company committed to a plan to close its manufacturing facility in Lake Zurich, Illinois, which historically was reported by the Company within the personal care component of its PE Films segment. In March 2020, this facility was shut down and the production of elastic materials it previously produced was transferred to Terre Haute, Indiana. As of September 30, 2020, the held for sale criteria was met since the Company expects the sale of the facility to be completed within one year. The disposal group carrying value of $4.6 million consists of land, building, and building improvements and is reported in "Prepaid expenses and other" in the Consolidated Balance Sheet. These assets were not included as part of the sale of the Personal Care business.

Earnings Per Share [Abstract]
Earnings Per Share	Basic earnings per share is computed by dividing net income (loss) from continuing and discontinued operations by the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed by dividing net income (loss) from continuing and discontinued operations by the weighted average common and potentially dilutive common equivalent shares outstanding, determined as follows: Three Months Ended Nine Months Ended September 30, September 30, (In thousands) 2020 2019 2020 2019 Weighted average shares outstanding used to compute basic earnings per share 33,439 33,271 33,396 33,222 Incremental dilutive shares attributable to stock options and restricted stock — 14 — 8 Shares used to compute diluted earnings per share 33,439 33,285 33,396 33,230 Incremental shares attributable to stock options and restricted stock are computed under the treasury stock method using the average market price during the related period. The Company had a net loss from continuing operations for the three and nine months ended September 30, 2020, so there is no dilutive impact for such shares. If the Company had reported net income from continuing operations for the three and nine months ended September 30, 2020, average out-of-the-money options to purchase shares that were excluded from the calculation of incremental shares attributable to stock options and restricted stock were 1,509,429 and 1,253,278, respectively.

Investments, Debt and Equity Securities [Abstract]
Investments and Other Noncurrent Assets	In August 2007 and December 2008, the Company made an aggregate investment of $7.5 million in kaleo, Inc. (“kaléo”), a privately held specialty pharmaceutical company dedicated to building innovative solutions for serious and life-threatening medical conditions. Tredegar owns Series A-3 Preferred Stock and Series B Preferred Stock in kaléo that, taken together, represents on a fully-diluted basis an approximate 18% interest in kaléo. Tredegar accounts for its investment in kaléo under the fair value option. At the time of the initial investment, the Company elected the fair value option of accounting since its investment objectives were similar to those of venture capitalists, which typically do not have controlling financial interests. The estimated fair value of the Company’s investment was $34.5 million as of September 30, 2020 and $95.5 million as of December 31, 2019. The Company recognized a decrease in value on its investment in kaléo of $36.2 million ($28.2 million after income taxes) in the third quarter of 2020, and a decline of $61.0 million ($47.7 million after income taxes) since the December 31, 2019 valuation. The decline in estimated fair value during the first nine months of 2020 was primarily due to: (i) lower expectations for 2020 earnings before interest, taxes, depreciation and amortization ("EBITDA") and net cash flow associated with lower market demand for epinephrine delivery devices, resulting from COVID-19-related delays in in-person back-to-school schedules which significantly impacted kaleo’s peak back-to-school season, and social distancing guidelines which disrupted 2020 summer and after-school activities, (ii) pricing pressure, and (iii) a higher private company liquidity discount. kaléo’s stock is not publicly traded. The net appreciation on its investment of $28.5 million ($23.4 million after taxes) in the first nine months of 2019, included a pre-tax cash dividend of $17.6 million paid on April 30, 2019. Future dividends are subject to the discretion of kaléo’s board of directors. Amounts recognized associated with the Company’s investment in kaléo are included in “Other income (expense), net” in the consolidated statements of income and separately stated in the net sales and EBITDA from ongoing operations by segment table in Note 11. The Company estimated the fair value of its investment in kaléo at September 30, 2020 by: (i) computing the weighted average estimated enterprise value (“EV”) utilizing both the discounted cash flow method (the “DCF Method”) and the application of a market multiple to EBITDA (the “EBITDA Multiple Method”), (ii) applying adjustments for any surplus or deficient working capital and estimates of contingent liabilities, (iii) adding cash and cash equivalents, (iv) subtracting interest-bearing debt, (v) subtracting a private company liquidity discount estimated at approximately 20% at September 30, 2020 (versus 10% at December 31, 2019 and 10% at September 30, 2019) of the net result of (i) through (iv), and (vi) applying liquidation preferences and fully diluted ownership percentages to the estimated equity value computed in (i) through (v). The Company’s estimate of kaléo’s EV as of September 30, 2020 was determined by weighting the EBITDA Multiple Method by 20% and the DCF Method by 80% compared to an 80% and 20% weighting of the EBITDA Multiple Method and DCF Method, respectively, used in the Company's estimate of kaléo’s EV as of December 31, 2019. A heavier weighting towards the DCF Method as of September 30, 2020 was used as it reflects the significant decline in kaléo’s EBITDA during the three months ended September 30, 2020 and is based on kaléo's current projections that assume ongoing pricing pressures and additional research and development ("R&D") spending for new products. The DCF Method projections rely on numerous assumptions and Level 3 inputs, including estimating market growth, market share, pricing, net margins (after allowances for temporary discounts, prompt pay discounts, product returns, wholesaler fees, chargebacks, rebates and co-pays), selling expenses, R&D expenses, general and administrative expenses, income taxes on unlevered pretax income, working capital, capital expenditures and the risk-adjusted discount rate. In addition, there are various regulatory and legal enforcement efforts, including an ongoing Department of Justice investigation related to kaléo’s discontinued Evzio business, which could have a material adverse effect on kaléo’s business that require assessment in any valuation method applied. The table below provides a sensitivity analysis of the estimated fair value at September 30, 2020, of the Company’s investment in kaléo for changes in the EBITDA multiple used in applying the EBITDA Multiple Method and the changes in the weighting of the DCF Method.

Derivative Financial Instrument

Summary of Derivative Instruments [Abstract]
Derivative Financial Instruments	Tredegar uses derivative financial instruments for the purpose of hedging margin exposure from fixed-price forward sales contracts in Aluminum Extrusions and exposure from currency volatility that exist as part of ongoing business operations (primarily in Flexible Packaging Films). These derivative financial instruments are designated as and qualify as cash flow hedges and are recognized in the consolidated balance sheet at fair value. The fair value of derivative instruments recorded on the consolidated balance sheets are based upon Level 2 inputs. If individual derivative instruments with the same counterparty can be settled on a net basis, the Company records the corresponding derivative fair values as a net asset or net liability. In the normal course of business, Aluminum Extrusions enters into fixed-price forward sales contracts with certain customers for the future sale of fixed quantities of aluminum extrusions at scheduled intervals. In order to hedge margin exposure created from the fixing of future sales prices relative to volatile raw material (aluminum) costs, Aluminum Extrusions enters into a combination of forward purchase commitments and futures contracts to acquire or hedge aluminum, based on the scheduled purchases for the firm sales commitments. The fixed-price firm sales commitments and related hedging instruments generally have durations of not more than 12 months. The notional amount of aluminum futures contracts that hedged future purchases of aluminum to meet fixed-price forward sales contract obligations was $15.7 million (16.8 million pounds of aluminum) at September 30, 2020 and $20.2 million (19.6 million pounds of aluminum) at December 31, 2019. The table below summarizes the location and gross amounts of aluminum futures contract fair values (Level 2) in the consolidated balance sheets as of September 30, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 (In thousands) Balance Sheet Fair Balance Sheet Fair Derivatives Designated as Hedging Instruments Asset derivatives: Aluminum futures contracts Accrued expenses $ 659 Accrued expenses $ 6 Liability derivatives: Aluminum futures contracts Accrued expenses (783) Accrued expenses (1,259) Net asset (liability) $ (124) $ (1,253) In the event that a counterparty to an aluminum fixed-price forward sales contract chooses not to take delivery of its aluminum extrusions, the customer is contractually obligated to compensate Aluminum Extrusions for any losses on the related aluminum futures and/or forward contracts through the date of cancellation. The table below summarizes the location and gross amounts of foreign currency forward contract fair values (Level 2) in the consolidated balance sheets as of September 30, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 (In thousands) Balance Sheet Fair Balance Sheet Fair Derivatives Designated as Hedging Instruments Asset derivatives: Foreign currency forward contracts Prepaid expenses and other $ — Prepaid expenses and other $ 83 Liability derivatives: Foreign currency forward contracts Accrued expenses (3,000) Accrued expenses (935) Net asset (liability) $ (3,000) $ (852) The Company's earnings are exposed to foreign currency exchange risk primarily through the translation of the financial statements of subsidiaries that have a functional currency other than the U.S. Dollar. The Company estimates that the net mismatch translation exposure for the Flexible Packaging Film's business unit in Brazil (“Terphane Ltda.”) of its sales and raw materials quoted or priced in U.S. Dollars and its variable conversion, fixed conversion and sales, general and administrative costs (before depreciation and amortization) quoted or priced in Brazilian Real is annual net costs of 134 million Brazilian Real ("R$"). Terphane Ltda. has the following outstanding foreign exchange average forward rate contracts to purchase Brazilian Real and sell U.S. Dollars: USD Notional Amount (000s) Average Forward Rate Contracted on USD/BRL R$ Equivalent Amount (000s) Applicable Month Estimated % of Terphane Ltda.

By changing the currency risk associated with these U.S. Dollar sales, the derivatives have the effect of offsetting operating costs quoted or priced in Brazilian Real and decreasing the net exposure to Brazilian Real in the consolidated statements of income. The pre-tax net fair value of the open forward contracts was a negative $2.4 million as of September 30, 2020. These derivative contracts involve elements of market risk that are not reflected on the consolidated balance sheet, including the risk of dealing with counterparties and their ability to meet the terms of the contracts. The counterparties to any forward purchase commitments are major aluminum brokers and suppliers, and the counterparties to any aluminum futures contracts are major financial institutions. Fixed-price forward sales contracts are only made available to the best and most credit-worthy customers. The counterparties to the Company’s foreign currency cash flow hedge contracts are major financial institutions. The pretax effect on net income (loss) and other comprehensive income (loss) of derivative instruments classified as cash flow hedges and described in the previous paragraphs for the three and nine month periods ended September 30, 2020 and 2019 is summarized in the table below: (In thousands) Cash Flow Derivative Hedges Three Months Ended September 30, Aluminum Futures Contracts Foreign Currency Forwards 2020 2019 2020 2020 2019 2019 Amount of pretax gain (loss) recognized in other comprehensive income (loss) $ 1,158 $ (449) $ — $ (655) $ — $ (1,501) Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (effective portion) Cost of Cost of Cost of Selling, general & admin Cost of Selling, general & admin Amount of pretax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income effective portion) $ (575) $ (816) $ 15 $ (1,767) $ 15 $ (101) Nine Months Ended September 30, Aluminum Futures Contracts Foreign Currency Forwards 2020 2019 2020 2020 2019 2019 Amount of pre-tax gain (loss) recognized in other comprehensive income (loss) $ (1,637) $ (1,887) $ — $ (6,015) $ — $ (1,598) Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (effective portion) Cost of Cost of Cost of Selling, general & admin Cost of Selling, general & admin Amount of pre-tax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (effective portion) $ (2,766) $ (2,039) $ 46 $ (4,359) $ 46 $ (661) As of September 30, 2020, the Company expects $0.1 million of unrealized after-tax losses on derivative instruments reported in accumulated other comprehensive income (loss) to be reclassified to earnings within the next 12 months. For the three and nine month periods ended September 30, 2020 and 2019, net gains or losses realized, from previously unrealized net gains or losses on hedges that had been discontinued, were not material.

Retirement Benefits [Abstract]
Pension And Other Post-Retirement Benefits	Tredegar sponsors a noncontributory defined benefit (pension) plan covering certain current and former U.S. employees. The plan for salaried and hourly employees currently in effect is based on a formula using the participant’s years of service and compensation or using the participant’s years of service and a dollar amount. The plan is closed to new participants and pay for active plan participants for benefit calculations was frozen as of December 31, 2007. As of January 31, 2018, the plan no longer accrued benefits associated with crediting employees for service, thereby freezing all future benefits under the plan. The components of net periodic benefit cost for the pension and other postretirement benefit programs reflected in the consolidated statements of income for the three and nine month periods ended September 30, 2020 and 2019, are shown below: Pension Benefits Other Post-Retirement Benefits Three Months Ended September 30, Three Months Ended September 30, (In thousands) 2020 2019 2020 2019 Service cost $ — $ — $ 9 $ 9 Interest cost 2,535 3,067 60 72 Expected return on plan assets (2,804) (3,404) — — Amortization of prior service costs, (gains) losses and net transition asset 3,814 2,729 (47) (58) Net periodic benefit cost $ 3,545 $ 2,392 $ 22 $ 23 Pension Benefits Other Post-Retirement Benefits Nine Months Ended September 30, Nine Months Ended September 30, (In thousands) 2020 2019 2020 2019 Service cost $ — $ — $ 28 $ 25 Interest cost 7,605 9,202 180 218 Expected return on plan assets (8,412) (10,212) — — Amortization of prior service costs, (gains) losses and net transition asset 11,441 8,188 (141) (173) Net periodic benefit cost $ 10,634 $ 7,178 $ 67 $ 70 Pension and other postretirement liabilities were $105.3 million and $108.1 million at September 30, 2020 and December 31, 2019, respectively ($0.7 million included in “Accrued expenses” at September 30, 2020 and December 31, 2019, with the remainder included in “Pension and other postretirement benefit obligations, net” in the consolidated balance sheets). The Company’s total required pension contributions for 2020 are expected to be $12.3 million; however, pursuant to the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"), the Company has elected as of September 30, 2020, to defer payment of $7.9 million of contributions until January 1, 2021. A $1.8 million pension plan contribution was made in January 2020 prior to the enactment of the CARES Act. Tredegar funds its other postretirement benefits on a claims-made basis; for 2020, the Company anticipates the amount will be consistent with amounts paid for the year ended December 31, 2019, or approximately $0.3 million.

Segment Reporting [Abstract]
Segment Reporting	The Company’s business segments are Aluminum Extrusions, PE Films, and Flexible Packaging Films. Information by business segment is reported below. There are no accounting transactions between segments and no allocations to segments. All historical results for the Personal Care business have been presented as discontinued operations. The surface protection component of the PE Films segment now includes Pottsville Packaging. The Company’s reportable segments are based on its method of internal reporting, which is generally segregated by differences in products. Accounting standards for presentation of segments require an approach based on the way the Company organizes the segments for making operating decisions and how the chief operating decision maker (“CODM”) assesses performance. EBITDA from ongoing operations is the key profitability measure used by the CODM (Tredegar’s President and Chief Executive Officer) for purposes of assessing financial performance. The Company uses sales less freight (“net sales”) from continuing operations as its measure of revenues from external customers at the segment level. This measure is separately included in the financial information regularly provided to the CODM. The following table presents net sales and EBITDA from ongoing operations by segment for the three and nine months ended September 30, 2020 and 2019: Three Months Ended September 30, Nine Months Ended September 30, (In thousands) 2020 2019 2020 2019 Net Sales Aluminum Extrusions $ 115,621 $ 129,505 $ 339,566 $ 405,310 PE Films 26,440 34,487 103,444 99,313 Flexible Packaging Films 35,856 34,888 100,534 101,950 Total net sales 177,917 198,880 543,544 606,573 Add back freight 6,453 7,088 19,222 21,438 Sales as shown in the Consolidated Statements of Income $ 184,370 $ 205,968 $ 562,766 $ 628,011 EBITDA from Ongoing Operations Aluminum Extrusions: Ongoing operations: EBITDA $ 16,540 $ 16,464 $ 41,496 $ 51,231 Depreciation & amortization (4,251) (4,317) (12,632) (12,481) EBIT 12,289 12,147 28,864 38,750 Plant shutdowns, asset impairments, restructurings and other (720) (610) (2,637) (667) Goodwill impairment — — (13,696) — Trade name accelerated amortization — (2,510) — (2,510) PE Films: Ongoing operations: EBITDA 6,041 10,257 33,928 30,452 Depreciation & amortization (1,785) (1,458) (4,868) (4,380) EBIT 4,256 8,799 29,060 26,072 Plant shutdowns, asset impairments, restructurings and other (56) (60) (225) (555) Flexible Packaging Films: Ongoing operations: EBITDA 9,546 4,394 22,594 10,477 Depreciation & amortization (443) (394) (1,306) (1,101) EBIT 9,103 4,000 21,288 9,376 Plant shutdowns, asset impairments, restructurings and other (3) — (14) — Total 24,869 21,766 62,640 70,466 Interest income 11 11 43 25 Interest expense 494 859 1,598 3,354 Gain (loss) on investment in kaléo accounted for under fair value method (36,200) 4,300 (61,000) 28,482 Stock option-based compensation costs 518 791 1,786 2,060 Corporate expenses, net 10,586 9,198 29,915 25,538 Income (loss) from continuing operations before income taxes (22,918) 15,229 (31,616) 68,021 Income tax expense (benefit) (5,942) 177 (8,308) 10,550 Income (loss) from continuing operations (16,976) 15,052 (23,308) 57,471 Income (loss) from discontinued operations, net of tax (48,237) 2,081 (53,031) (6,076) Net income (loss) $ (65,213) $ 17,133 $ (76,339) $ 51,395 The following table presents identifiable assets by segment at September 30, 2020 and December 31, 2019: (In thousands) September 30, 2020 December 31, 2019 Aluminum Extrusions $ 238,683 $ 265,027 PE Films 169,195 122,136 Flexible Packaging Films 61,903 74,016 Subtotal 469,781 461,179 General corporate 16,882 111,788 Cash and cash equivalents 35,022 31,422 Assets of discontinued operations 45,955 108,279 Total $ 567,640 $ 712,668 The following tables disaggregate the Company’s revenue by geographic area and product group for the three and nine months ended September 30, 2020 and 2019: Net Sales by Geographic Area (a) Three Months Ended September 30, Nine Months Ended September 30, (In thousands) 2020 2019 2020 2019 United States $ 129,654 $ 145,629 $ 395,207 $ 455,509 Exports from the United States to: Asia 14,255 23,163 59,816 61,037 Latin America 465 880 1,953 1,359 Canada 7,200 2,120 13,359 10,352 Europe 1,468 1,494 4,272 4,227 Operations outside the United States: Brazil 24,875 25,594 68,937 73,864 China — — — 225 Total $ 177,917 $ 198,880 $ 543,544 $ 606,573 (a) Export sales relate primarily to PE Films.

Income Tax Disclosure [Abstract]
Income Taxes	Tredegar recorded a tax benefit of $8.3 million on a pretax loss from continuing operations of $31.6 million in the first nine months of 2020. Therefore, the effective tax rate in the first nine months of 2020 was 26.2%, compared to 15.5% in the first nine months of 2019. The quarterly effective tax rate is an estimate based on a proration of the components of the Company’s estimated annual effective tax rate and discrete items recorded during the first nine months of the year. The significant differences between the U.S. federal statutory rate and the effective income tax rate for the nine months ended September 30, 2020 and 2019 are as follows: (In thousands, except percentages) 2020 2019 Nine Months Ended September 30, Amount % Amount % Income tax (benefit) expense at federal statutory rate $ (6,639) 21.0 % $ 14,284 21.0 % Foreign tax incentives (3,412) 10.8 % (2,416) (3.6) % Changes in estimates related to prior year tax provision (1,001) 3.2 % (36) (0.1) % Research and development tax credit (612) 1.9 % (336) (0.5) % State taxes, net of federal income tax benefit (537) 1.7 % 560 0.8 % Tax contingency accruals and tax settlements (148) 0.5 % (2,527) (3.7) % Valuation allowance due to foreign losses and impairments — — % (2,074) (3.0) % Tax impact of dividend received — — % (1,016) (1.5) % Foreign Derived Intangible Income (FDII) — — % (546) (0.8) % Valuation allowance for capital loss carry-forwards 61 (0.2) % — — % Non-deductible expenses 312 (1.0) % 242 0.4 % Stock-based compensation 240 (0.8) % (132) (0.2) % U.S. Tax on Foreign Branch Income 656 (2.1) % 3,034 4.5 % Foreign rate differences 2,772 (8.8) % 1,513 2.2 % Income tax expense (benefit) at effective income tax rate $ (8,308) 26.2 % $ 10,550 15.5 % Tredegar accrues U.S. federal income taxes on unremitted earnings of foreign subsidiaries where required. However, due to changes in the taxation of dividends under the U.S. Tax Cuts and Jobs Act of 2017, Tredegar will only record U.S. federal income taxes on unremitted earnings of its foreign subsidiaries where Tredegar cannot take steps to eliminate any potential tax on future distributions from its foreign subsidiaries. The Brazilian federal statutory income tax rate is a composite of 34.0% (25.0% of income tax and 9.0% of social contribution on income). Terphane Ltda.’s manufacturing facility in Brazil is the beneficiary of certain income tax incentives that allow for a reduction in the statutory Brazilian federal income tax rate to 15.25% levied on the operating profit on certain of its products. The incentives have been granted for a 13-year period, from the commencement date of January 1, 2015. The benefit from the tax incentives was $3.4 million and $2.4 million in the first nine months of 2020 and 2019, respectively. Tredegar and its subsidiaries file income tax returns in the U.S., various states, and jurisdictions outside the U.S. With exceptions for some U.S. states and non-U.S. jurisdictions, Tredegar and its subsidiaries are no longer subject to U.S. federal, state or non-U.S. income tax examinations by tax authorities for years before 2016. During the nine months ended September 30, 2020, new legislation was enacted and new IRS guidance was issued to provide relief to businesses in response to COVID-19. We have evaluated the tax provisions included in legislation such as the CARES Act, as well as recent IRS guidance and we do not expect it to have a significant impact on our financial position, results of operations or cash flows.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	Tredegar uses derivative financial instruments for the purpose of hedging margin exposure from fixed-price forward sales contracts in Aluminum Extrusions and exposure from currency volatility that exist as part of ongoing business operations (primarily in Flexible Packaging Films). These derivative financial instruments are designated as and qualify as cash flow hedges and are recognized in the consolidated balance sheet at fair value. The fair value of derivative instruments recorded on the consolidated balance sheets are based upon Level 2 inputs. If individual derivative instruments with the same counterparty can be settled on a net basis, the Company records the corresponding derivative fair values as a net asset or net liability. In the normal course of business, Aluminum Extrusions enters into fixed-price forward sales contracts with certain customers for the future sale of fixed quantities of aluminum extrusions at scheduled intervals. In order to hedge margin exposure created from the fixing of future sales prices relative to volatile raw material (aluminum) costs, Aluminum Extrusions enters into a combination of forward purchase commitments and futures contracts to acquire or hedge aluminum, based on the scheduled purchases for the firm sales commitments. The fixed-price firm sales commitments and related hedging instruments generally have durations of not more than 12 months. The notional amount of aluminum futures contracts that hedged future purchases of aluminum to meet fixed-price forward sales contract obligations was $15.7 million (16.8 million pounds of aluminum) at September 30, 2020 and $20.2 million (19.6 million pounds of aluminum) at December 31, 2019. The table below summarizes the location and gross amounts of aluminum futures contract fair values (Level 2) in the consolidated balance sheets as of September 30, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 (In thousands) Balance Sheet Fair Balance Sheet Fair Derivatives Designated as Hedging Instruments Asset derivatives: Aluminum futures contracts Accrued expenses $ 659 Accrued expenses $ 6 Liability derivatives: Aluminum futures contracts Accrued expenses (783) Accrued expenses (1,259) Net asset (liability) $ (124) $ (1,253) In the event that a counterparty to an aluminum fixed-price forward sales contract chooses not to take delivery of its aluminum extrusions, the customer is contractually obligated to compensate Aluminum Extrusions for any losses on the related aluminum futures and/or forward contracts through the date of cancellation.

The Company estimates that the net mismatch translation exposure for the Flexible Packaging Film's business unit in Brazil (“Terphane Ltda.”) of its sales and raw materials quoted or priced in U.S. Dollars and its variable conversion, fixed conversion and sales, general and administrative costs (before depreciation and amortization) quoted or priced in Brazilian Real is annual net costs of 134 million Brazilian Real ("R$").

By changing the currency risk associated with these U.S. Dollar sales, the derivatives have the effect of offsetting operating costs quoted or priced in Brazilian Real and decreasing the net exposure to Brazilian Real in the consolidated statements of income. The pre-tax net fair value of the open forward contracts was a negative $2.4 million as of September 30, 2020. These derivative contracts involve elements of market risk that are not reflected on the consolidated balance sheet, including the risk of dealing with counterparties and their ability to meet the terms of the contracts. The counterparties to any forward purchase commitments are major aluminum brokers and suppliers, and the counterparties to any aluminum futures contracts are major financial institutions. Fixed-price forward sales contracts are only made available to the best and most credit-worthy customers. The counterparties to the Company’s foreign currency cash flow hedge contracts are major financial institutions. The pretax effect on net income (loss) and other comprehensive income (loss) of derivative instruments classified as cash flow hedges and described in the previous paragraphs for the three and nine month periods ended September 30, 2020 and 2019 is summarized in the table below: (In thousands) Cash Flow Derivative Hedges Three Months Ended September 30, Aluminum Futures Contracts Foreign Currency Forwards 2020 2019 2020 2020 2019 2019 Amount of pretax gain (loss) recognized in other comprehensive income (loss) $ 1,158 $ (449) $ — $ (655) $ — $ (1,501) Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (effective portion) Cost of Cost of Cost of Selling, general & admin Cost of Selling, general & admin Amount of pretax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income effective portion) $ (575) $ (816) $ 15 $ (1,767) $ 15 $ (101) Nine Months Ended September 30, Aluminum Futures Contracts Foreign Currency Forwards 2020 2019 2020 2020 2019 2019 Amount of pre-tax gain (loss) recognized in other comprehensive income (loss) $ (1,637) $ (1,887) $ — $ (6,015) $ — $ (1,598) Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (effective portion) Cost of Cost of Cost of Selling, general & admin Cost of Selling, general & admin Amount of pre-tax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (effective portion) $ (2,766) $ (2,039) $ 46 $ (4,359) $ 46 $ (661) As of September 30, 2020, the Company expects $0.1 million of unrealized after-tax losses on derivative instruments reported in accumulated other comprehensive income (loss) to be reclassified to earnings within the next 12 months.
