Organization, Consolidation and Presentation of Financial Statements [Abstract]
General Information	GENERAL INFORMATION Nature of Business and Basis of Presentation Graphic Packaging Holding Company (“GPHC” and, together with its subsidiaries, the “Company”) is committed to providing consumer packaging that makes a world of difference. The Company is a leading provider of paper-based packaging solutions for a wide variety of products to food, beverage, foodservice and other consumer products companies. The Company operates on a global basis, is one of the largest producers of folding cartons in the United States ("U.S.") and holds leading market positions in coated unbleached kraft paperboard ("CUK"), coated-recycled paperboard ("CRB") and solid bleached sulfate paperboard ("SBS"). On January 1, 2018, GPHC, a Delaware corporation, International Paper Company, a New York corporation (“IP”), Graphic Packaging International Partners, LLC, a Delaware limited liability company formerly known as Gazelle Newco LLC and a wholly owned subsidiary of the Company (“GPIP”), and Graphic Packaging International, LLC, a Delaware limited liability company formerly known as Graphic Packaging International, Inc. and a subsidiary of GPIP (“GPIL”), completed a series of transactions pursuant to an agreement dated October 23, 2017, among the foregoing parties (the “Transaction Agreement”). Pursuant to the Transaction Agreement (i) a wholly owned subsidiary of the Company transferred its ownership interest in GPIL to GPIP; (ii) IP transferred its North America Consumer Packaging (“NACP”) business to GPIP, which was then subsequently transferred to GPIL; (iii) GPIP issued membership interests to IP, and IP was admitted as a member of GPIP; and (iv) GPIL assumed certain indebtedness of IP (the "NACP Combination"). GPI Holding III, LLC, an indirect wholly-owned subsidiary of the Company (“GPI Holding”), is the managing member of GPIP. At closing of the NACP Combination, GPIP issued 309,715,624 common units or 79.5% of the membership interests in GPIP to GPI Holding and 79,911,591 common units or 20.5% of the membership interests in GPIP to IP. Subject to certain restrictions, the common units held by IP are exchangeable into shares of common stock of GPHC or cash. The following diagram illustrates the organization of the Company immediately subsequent to the transactions described above (not including subsidiaries of GPIL): The Company’s customers include many of the world’s most widely recognized companies and brands with prominent market positions in beverage, food, foodservice, and other consumer products. The Company strives to provide its customers with packaging solutions designed to deliver marketing and performance benefits at a competitive cost by capitalizing on its low-cost paperboard mills and converting facilities, its proprietary carton and packaging designs, and its commitment to quality and service. GPHC, GPI Holding I, Inc., GPI Holding II, Inc. and GPI Holding III, LLC conduct no significant business operations and have no independent assets or operations other than intercompany transactions and their direct and indirect ownership of 79.5% of GPIP's membership interests, except for deferred tax assets held by GPHC. The Company’s Condensed Consolidated Financial Statements include all subsidiaries in which the Company has the ability to exercise direct or indirect control over operating and financial policies. Intercompany transactions and balances are eliminated in consolidation. In the Company’s opinion, the accompanying Condensed Consolidated Financial Statements contain all normal recurring adjustments necessary to present fairly the financial position, results of operations and cash flows for the interim periods. The Company’s year end Condensed Consolidated Balance Sheet data was derived from audited financial statements. The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with instructions to Form 10-Q and Rule 10-01 of Regulation S-X and do not include all the information required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for complete financial statements. Therefore, these Condensed Consolidated Financial Statements should be read in conjunction with GPHC’s Form 10-K for the year ended December 31, 2017 . In addition, the preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates and changes in these estimates are recorded when known. For a summary of the Company’s significant accounting policies, please refer to GPHC’s Form 10-K for the year ended December 31, 2017 . Revenue Recognition The Company has two primary activities from which it generates revenue from contracts with customers, and revenue is disaggregated primarily by geography and type of activity as further explained in " Note 10-Segments. " All reportable segments and the Australia and Pacific Rim operating segments recognize revenue under the same method, allocate transaction price using similar methods, and have similar economic factors impacting the uncertainty of revenue and related cash flows. Revenue is recognized on the Company's annual and multi-year supply contracts when the Company satisfies the performance obligation by transferring control over the product or service to a customer, which is generally based on shipping terms and passage of title under the point-in-time method of recognition. For the three months ended September 30, 2018 and 2017, the Company recognized $1,525.7 million and $1,132.0 million , respectively, of revenue from contracts with customers. For the nine months ended September 30, 2018 and 2017 , the Company recognized $4,502.7 million and $3,277.8 million , respectively, of revenue from contracts with customers. The transaction price allocated to each performance obligation consists of the stand alone selling price, estimates of rebates and other sales or contract renewal incentives, and cash discounts and sales returns ("Variable Consideration"). Estimates are made for Variable Consideration based on contract terms and historical experience of actual results and are applied to the performance obligations as they are settled. Purchases by the Company’s principal customers are manufactured and shipped with minimal lead time, therefore performance obligations are generally settled shortly after manufacturing and shipment. The Company's contract assets consist primarily of contract renewal incentive payments to customers which are amortized over the period in which performance obligations related to the contract renewal are satisfied. As of September 30, 2018 and December 31, 2017 contract assets were $21.7 million and $11.7 million , respectively. The Company's contract liabilities consist principally of rebates, and as of September 30, 2018 and December 31, 2017 were $47.7 million and $28.6 million , respectively. The Company did not have a material amount relating to backlog orders at September 30, 2018 or December 31, 2017 . Accounts Receivable and Allowances The Company has entered into agreements to sell, on a revolving basis, certain trade accounts receivable to third party financial institutions. Transfers under these agreements meet the requirements to be accounted for as sales in accordance with the Transfers and Servicing topic of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification (the "Codification"). The loss on sale is not material and is included in Other Expense, Net on the Condensed Consolidated Statement of Operations. The following table summarizes the activity under these programs as of September 30, 2018 and 2017 , respectively: Nine Months Ended September 30, In millions 2018 2017 Receivables Sold and Derecognized $ 2,507.2 $ 1,027.9 Proceeds Collected on Behalf of Financial Institutions 2,449.8 962.9 Net Proceeds (Paid to) Received From Financial Institutions (121.7 ) 65.0 Deferred Purchase Price (a) 282.3 26.3 (a) Included in Receivables, Net and represents receivables from the financial institution which have purchasing and servicing of receivable agreements, which is a Level 3 fair value measure. The Company has also entered into various factoring and supply chain financing arrangements, which also qualify for sale accounting in accordance with the Transfers and Servicing topic of the FASB Codification. For the nine months ended September 30, 2018 and 2017 , the Company sold receivables of approximately $86 million and $43 million , respectively, related to these factoring arrangements. Receivables sold under all programs subject to continuing involvement, which consist principally of collection services, at September 30, 2018 and December 31, 2017 , were approximately $641 million and $583 million , respectively. Capital Allocation Plan During the first nine months of 2018, the Company's board of directors declared three regular quarterly dividends of $0.075 per share of common stock to shareholders of record as follows: Date Declared Record Date Payment Date February 22, 2018 March 15, 2018 April 5, 2018 May 23, 2018 June 15, 2018 July 5, 2018 July 26, 2018 September 15, 2018 October 5, 2018 On January 10, 2017, the Company's board of directors authorized an additional share repurchase program to allow the Company to purchase up to $ 250 million of the Company's issued and outstanding shares of common stock through open market purchases, privately negotiated transactions and Rule 10b5-1 plans (the "2017 share repurchase program"). The original $250 million share repurchase program was authorized on February 4, 2015 (the "2015 share repurchase program"). During the first nine months of 2018 , the Company did no t repurchase any shares of its common stock. The Company repurchased approximately 4.5 million shares at an average price of $13.08 during the nine months ended September 30, 2017 , including approximately 1.4 million shares repurchased under the 2015 share repurchase program thereby completing that program. As of September 30, 2018 , the Company has approximately $210 million available for additional repurchases under the 2017 share repurchase program. Business Combinations, Gain on Sale of Assets and Shutdown and Other Special Charges, Net The following table summarizes the transactions recorded in Business Combinations, (Gain) on Sale of Assets and Shutdown and Other Special Charges, Net in the Condensed Consolidated Statements of Operations: Three Months Ended Nine Months Ended September 30, September 30, In millions 2018 2017 2018 2017 Charges Associated with Business Combinations $ 8.3 $ 2.3 $ 41.9 $ 10.0 Shutdown and Other Special Charges 1.4 1.3 4.2 8.3 Gain on Sale of Assets (37.1 ) — (38.6 ) — Total $ (27.4 ) $ 3.6 $ 7.5 $ 18.3 2018 On September 30, 2018, the Company acquired substantially all the assets of the foodservice business of Letica Corporation, a subsidiary of RPC Group PLC ("Letica Foodservice"), a producer of paperboard-based cold and hot cups and cartons. The acquisition includes two facilities located in Clarksville, Tennessee and Pittston, Pennsylvania. Letica Foodservice is included in the Americas Paperboard Packaging reportable segment. On August 31, 2018, the Company sold its previously closed coated recycled paperboard mill site in Santa Clara, California, resulting in a gain on sale of assets of $37.1 million . On June 12, 2018, the Company acquired substantially all the assets of PFP, LLC and its related entity, PFP Dallas Converting, LLC (collectively, "PFP"), a converter focused on the production of paperboard based air filter frames. The acquisition includes two facilities located in Lebanon, Tennessee and Lancaster, Texas. PFP is included in the Americas Paperboard Packaging reportable segment. On January 1, 2018, the Company completed the NACP Combination. The NACP business produces SBS paperboard and paper-based foodservice products. The NACP business includes two SBS mills located in Augusta, Georgia and Texarkana, Texas (included in Paperboard Mills reportable segment), three converting facilities in the U.S. (included in Americas Paperboard Packaging reportable segment) and one in the United Kingdom ("U.K.") (included in the Europe Paperboard Packaging reportable segment). 2017 On December 1, 2017, the Company acquired the assets of Seydaco Packaging Corp. and its affiliates National Carton and Coating Co., and Groupe Ecco Boites Pliantes Ltée (collectively, "Seydaco"), a folding carton producer focused on the foodservice, food, personal care, and household goods markets. The acquisition includes three folding carton facilities located in Mississauga, Ontario, St.-Hyacinthe, Québec, and Xenia, Ohio. On December 1, 2017, the Company closed its coated recycled paperboard mill in Santa Clara, California. This decision was made as a result of a thorough assessment of the facility's manufacturing capabilities and associated costs in the context of the Company's overall mill operating capabilities and cost structure. The financial impact is reflected in Shutdown and Other Special Charges in the table above. On October 4, 2017, the Company acquired Norgraft Packaging, S.A., ("Norgraft"), a leading folding carton producer in Spain focused on the food and household goods markets. The acquisition includes two folding carton facilities located in Miliaño and Requejada, Spain.

The acquisition includes two folding carton facilities located in New Albany, Indiana, focused on the production of paperboard based air filter frames and folding cartons. The Seydaco, Norgraft, and Carton Craft transactions are referred to collectively as the "2017 Acquisitions." Seydaco and Carton Craft are included in the Americas Paperboard Packaging Segment. Norgraft is included in the Europe Paperboard Packaging Segment. Charges associated with the NACP Combination, the PFP and Letica Foodservice acquisitions, and 2017 Acquisitions are reflected in Charges Associated with Business Combinations in the above table. For more information regarding the above acquisitions see " Note 3 - Business Combinations ." Adoption of New Accounting Standards Effective January 1, 2018, the Company adopted Accounting Standards Update ("ASU") No. 2017-09, Compensation - Stock Compensation (Topic 718); Scope of Modification Accounting. The amendments in this ASU provide guidance that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. If the value, vesting conditions or classification of the award changes, modification accounting will apply. The adoption of this standard did not have a material impact on the Company’s financial position, results of operations and cash flows. Effective January 1, 2018, the Company adopted ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715); Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The amendments in this ASU require the service cost component of net periodic benefit cost be reported in the same income statement line or lines as other compensation costs for employees. The other components of net periodic benefit cost are required to be reported separately from service costs and outside a subtotal of income from operations. Only the service cost component is eligible for capitalization. The adoption of this ASU was applied retrospectively for the reclassification of net periodic benefit expense, excluding service costs, in the Condensed Consolidated Statement of Operations. The adoption of this ASU did not have a material impact on the Company’s financial position, results of operations and cash flows. Effective January 1, 2018, the Company adopted ASU No. 2017-01, Business Combinations (Topic 805); Clarifying the Definition of a Business . The amendments in this ASU provide guidance in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. This ASU was adopted prospectively and did not have a material impact on the Company’s financial position, results of operations and cash flows. Effective January 1, 2018, the Company adopted ASU No. 2016-15, Statement of Cash Flows (Topic 230); Classification of Certain Cash Receipts and Cash Payments . The amendments in this ASU provide guidance on how certain cash receipts and payments should be presented in the statement of cash flows and was applied retrospectively. This ASU requires the Company to classify consideration received for beneficial interest obtained for selling trade receivables as investing instead of operating activities. The retrospective impact on the Company's consolidated statement of cash flows for the nine months ended September 30, 2017 was a $424.8 million decrease to cash provided by operating activities and a corresponding increase to cash provided by investing activities. Effective January 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), using the modified retrospective approach. Adoption of ASU No. 2014-09 requires that an entity recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company considered whether the adoption may require acceleration of revenue for products produced by the Company without an alternative use and when the Company would have a legally enforceable right of payment. The Company has determined that it does not have an enforceable right of payment for products produced but not yet shipped and recognizes all revenue under the point in time method. The adoption of ASU No. 2014-09 did not have a material impact on the Company's financial position, results of operations and cash flows. Accounting Standards Not Yet Adopted In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815); Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU better align the risk management activities and financial reporting for these hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company does not expect the adoption of this standard to have a material impact on the Company’s financial position, results of operations and cash flows. In January 2017, the FASB issued ASU No. 2017-04 Intangibles - Goodwill and Other (Topic 350); Simplifying the Test for Goodwill Impairment which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 of the goodwill impairment model. Step 2 measures a goodwill impairment loss by comparing the implied value of a reporting unit’s goodwill with the carrying amount of that goodwill. An entity would recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized is limited to the amount of goodwill allocated to that reporting unit. The guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for any impairment tests performed after January 1, 2017. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The amendments in this ASU require an entity to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures about leasing arrangements. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The updated guidance allows a modified retrospective adoption, which the Company plans to adopt. The Company has formed an implementation team including representatives from finance, information technology and supply chain to assist in the implementation of this standard. A software solution has been determined, and is being populated as the Company is gathering information on all of its leases. The adoption of this standard is expected to have a material impact on the Company’s financial position, but currently is not expected to have a material impact on the results of operations and cash flows.

Business Combinations [Abstract]
Business Combinations	BUSINESS COMBINATIONS On January 1, 2018, the Company completed the NACP Combination. The NACP business produces SBS paperboard and paper-based foodservice products. The NACP business includes two SBS mills located in Augusta, Georgia and Texarkana, Texas, three converting facilities in the U.S. and one in the U.K. Total consideration for the NACP Combination, including debt assumed of $660 million , was $1.9 billion . Management believes that the purchase price attributable to goodwill represents the benefits expected as the acquisition was made to continue to expand the Company's product offering, integrate paperboard from the Company's mills and to further optimize the Company's supply chain footprint. In conjunction with the NACP Combination, the Company executed a Tax Receivable Agreement ("TRA") with IP. Pursuant to elections under Section 754 of the Internal Revenue Code, the Company expects to obtain an increase with respect to the tax basis in the assets of GPIP and certain of its subsidiaries when IP exchanges or redeems any of its membership interests. The Company generally expects to treat redemptions or exchanges of membership interests by IP as direct purchases of membership interests for U.S. federal income tax purposes. Increases in tax basis may reduce the amounts that we would otherwise pay in the future to various tax authorities. The TRA provides for the payment by the Company to IP of 50% of the amount of any tax benefits projected to be realized by the Company upon IP's exchange of the partnership units into GPHC common stock. On September 30, 2018, the Company completed the Letica Foodservice acquisition. The acquisition includes two facilities in Clarksville, Tennessee and Pittston, Pennsylvania, focused on the production of paperboard-based cold and hot cups and cartons. The Company paid approximately $95 million using existing cash and borrowings under its revolving credit facility. On June 12, 2018, the Company completed the PFP acquisition. The Company paid approximately $34 million using existing cash and borrowings under its revolving credit facility. The acquisition includes two manufacturing facilities in Lebanon, Tennessee and Lancaster, Texas, focused on the production of paperboard-based air filter frames. The Company expects that goodwill related to the NACP Combination will no t be deductible for tax purposes. The Company expects that goodwill related to the Letica Foodservice and the PFP acquisitions will be deductible for tax purposes. The acquisition accounting for the NACP Combination and the Letica Foodservice and PFP acquisitions are preliminary based on the estimated fair values as of the combination date and are subject to adjustments in subsequent periods once the third party valuations are finalized.

These letters of credit are primarily used as security against its self-insurance obligations and workers’ compensation obligations. These letters of credit expire at various dates through 2019 unless extended. In connection with the consummation of the NACP Combination, GPIL entered into a Third Amended and Restated Credit Agreement dated January 1, 2018 (the “Amended and Restated Credit Agreement”). The Amended and Restated Credit Agreement effected an “amend and extend” transaction with respect to the Company’s existing senior credit facility by which, among other things: (i) the maturity date thereof was extended to January 1, 2023, (ii) the U.S. dollar commitment portion increased by $75 million , (iii) the applicable margin interest rate pricing grid levels were changed from those set forth in the prior credit facility, (iv) certain negative covenants contained in the prior credit facility were relaxed, and (v) certain amendments were effected so as to accommodate the transactions with IP. In addition to the Amended and Restated Credit Agreement, on January 1, 2018 the Company assumed the term loan indebtedness previously incurred by IP (the “Term Loan Credit Agreement”) in an aggregate amount of $660 million , repayable pursuant to the same amortization schedule (expressed as a percentage of the principal amount thereof) as the Term Loan A under the Amended and Restated Credit Agreement and has the same maturity date of January 1, 2023. The applicable margin interest rate pricing grid, covenants and other terms are substantially equivalent to those contained in the Amended and Restated Credit Agreement. The Term Loan Credit Agreement is secured by a lien and security interest in substantially all of the assets of GPIL on a pari passu basis with the liens and security interests securing the Amended and Restated Credit Agreement pursuant to the terms of a customary intercreditor agreement among the parties. The Amended and Restated Credit Agreement and Term Loan Credit Agreement are collectively referred to as the "Credit Agreement." The Credit Agreement is guaranteed by GPIP and certain domestic subsidiaries, and the 4.75% Senior Notes due 2021, 4.875% Senior Notes due 2022 and 4.125% Senior Notes due 2024 are guaranteed by GPHC.

The Credit Agreement and the indentures governing the 4.75% Senior Notes due 2021, 4.875% Senior Notes due 2022 and 4.125% Senior Notes due 2024 (the “Indentures”) limit the Company's ability to incur additional indebtedness. Additional covenants contained in the Credit Agreement and the Indentures may, among other things, restrict the ability of the Company to dispose of assets, incur guarantee obligations, prepay other indebtedness, repurchase stock, pay dividends and make other restricted payments, create liens, make equity or debt investments, make acquisitions, modify terms of the Indenture, engage in mergers or consolidations, change the business conducted by the Company and its subsidiaries, and engage in certain transactions with affiliates. Such restrictions could limit the Company’s ability to respond to changing market conditions, fund its capital spending program, provide for unexpected capital investments or take advantage of business opportunities. As of September 30, 2018 , the Company was in compliance with the covenants in the Credit Agreement and the Indentures.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments and Fair Value Measurement	FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENT The Company enters into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments under the Derivatives and Hedging topic of the FASB Codification and those not designated as hedging instruments under this guidance. The Company uses interest rate swaps, natural gas swap contracts, and forward exchange contracts. These derivative instruments are designated as cash flow hedges and, to the extent they are effective in offsetting the variability of the hedged cash flows, changes in the derivatives’ fair value are not included in current earnings but are included in Accumulated Other Comprehensive Loss. These changes in fair value will subsequently be reclassified to earnings, contemporaneously with and offsetting changes in the related hedged exposure. For more information regarding the Company’s financial instruments and fair value measurement, see “ Note 9 — Financial Instruments, Derivatives and Hedging Activities ” and “ Note 10 — Fair Value Measurement ” of the Notes to Consolidated Financial Statements of the Company’s 2017 Form 10-K. Interest Rate Risk The Company uses interest rate swaps to manage interest rate risks on future interest payments caused by interest rate changes on its variable rate term loan facility. Changes in fair value will subsequently be reclassified into earnings as a component of Interest Expense, Net as interest is incurred on amounts outstanding under the term loan facility. The following table summarizes the Company's current interest rate swap positions for each period presented as of September 30, 2018 : Start End (In Millions) Weighted Average Interest Rate 12/01/2017 10/01/2018 $250.0 1.16% 04/03/2018 01/01/2019 $150.0 2.03% 04/03/2018 01/01/2020 $150.0 2.25% 04/03/2018 10/01/2020 $150.0 2.36% 12/03/2018 01/01/2022 $120.0 2.92% 12/03/2018 01/04/2022 $80.0 2.79% Ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. During the first nine months of 2018 and 2017 , there were no amounts of ineffectiveness related to changes in the fair value of interest rate swap agreements. Additionally, there were no amounts excluded from the measure of effectiveness. Commodity Risk To manage risks associated with future variability in cash flows and price risk attributable to purchases of natural gas, the Company enters into natural gas swap contracts to hedge prices for a designated percentage of its expected natural gas usage. Such contracts are designated as cash flow hedges. The contracts are carried at fair value with changes in fair value recognized in Accumulated Other Comprehensive Loss, the resulting gain or loss reclassified into Cost of Sales concurrently with the recognition of the commodity consumed, and the ineffective portion of the swap contracts’ change in fair value recognized immediately in earnings. The Company has hedged approximately 40% and 20% of its expected natural gas usage for the remainder of 2018 and the first quarter of 2019, respectively. During the first nine months of 2018 and 2017 , there were minimal amounts of ineffectiveness related to changes in the fair value of natural gas swap contracts. Additionally, there were no amounts excluded from the measure of effectiveness. Foreign Currency Risk The Company enters into forward exchange contracts to manage risks associated with foreign currency transactions and future variability of cash flows arising from those transactions that may be adversely affected by changes in exchange rates. The contracts are carried at fair value with changes in fair value recognized in Accumulated Other Comprehensive Loss and gains/losses related to these contracts are recognized in Other Expense, Net or Net Sales , when appropriate. At September 30, 2018 , multiple forward exchange contracts existed that expire on various dates through the remainder of 2018 . Those purchased forward exchange contracts outstanding at September 30, 2018 and December 31, 2017 , when aggregated and measured in U.S. dollars at contractual rates at September 30, 2018 and December 31, 2017 , had notional amounts totaling $14.1 million and $66.1 million , respectively. No amounts were reclassified to earnings during the first nine months of 2018 or during 2017 in connection with forecasted transactions that were considered probable of not occurring and there was no amount of ineffectiveness related to changes in the fair value of foreign currency forward contracts. Additionally, there were no amounts excluded from the measure of effectiveness. Derivatives not Designated as Hedges The Company enters into forward exchange contracts to effectively hedge substantially all of its accounts receivables resulting from sales transactions and intercompany loans denominated in foreign currencies in order to manage risks associated with variability in cash flows that may be adversely affected by changes in exchange rates. At September 30, 2018 and December 31, 2017 , multiple foreign currency forward exchange contracts existed, with maturities ranging up to eighteen months. Those foreign currency exchange contracts outstanding at September 30, 2018 and December 31, 2017 , when aggregated and measured in U.S. dollars at exchange rates at September 30, 2018 and December 31, 2017 , had net notional amounts totaling $99.1 million and $90.1 million , respectively. Unrealized gains and losses resulting from these contracts are recognized in Other Expense, Net and approximately offset corresponding recognized but unrealized gains and losses on the remeasurement of these accounts receivable. Fair Value of Financial Instruments The Company’s derivative instruments are carried at fair value. The Company has determined that the inputs to the valuation of these derivative instruments are Level 2 in the fair value hierarchy. Level 2 inputs are defined as quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. The Company uses valuation techniques based on discounted cash flow analyses, which reflect the terms of the derivatives and use observable market-based inputs, including forward rates, and uses market price quotations obtained from independent derivatives brokers, corroborated with information obtained from independent pricing service providers. As of September 30, 2018 , the Company had a gross derivative asset of $4.9 million and a gross derivative liability of $1.7 million , related to interest rate, foreign currency and commodity contracts. As of September 30, 2018 , there has not been any significant impact to the fair value of the Company’s derivative liabilities due to its own credit risk. Similarly, there has not been any significant adverse impact to the Company’s derivative assets based on evaluation of the Company’s counterparties’ credit risks. The fair values of the Company’s other financial assets and liabilities at September 30, 2018 and December 31, 2017 approximately equal the carrying values reported on the Condensed Consolidated Balance Sheets except for Long-Term Debt. The fair value of the Company’s Long-Term Debt (excluding capital leases and deferred financing fees) was $2,896.1 million and $2,299.1 million as compared to the carrying amounts of $2,902.4 million and $2,247.9 million as of September 30, 2018 and December 31, 2017 , respectively. The fair value of the Company’s Total Debt, including the Senior Notes, are based on quoted market prices (Level 2 inputs). Level 2 valuation techniques for Long-Term Debt are based on quotations obtained from independent pricing service providers. The following is a rollforward of pre-tax Accumulated Other Comprehensive (Loss) Income pertaining to derivative instruments: In millions Balance at December 31, 2017 $ (0.3 ) Reclassification to Earnings (0.1 ) Current Period Change in Fair Value 3.9 Balance at September 30, 2018 $ 3.5 At September 30, 2018 , the Company expects to reclassify approximately $2.7 million of gains in the next twelve months from Accumulated Other Comprehensive Loss to earnings, contemporaneously with and offsetting changes in the related hedged exposure. The actual amount that will be reclassified to future earnings may vary from this amount as a result of changes in market conditions.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Substantially all of the Company’s operations are held through its majority investment in GPIP, a subsidiary that is classified as a partnership for U.S. income tax purposes and is generally not subject to domestic income tax expense. As a result, the consolidated financial statements exclude the domestic tax effect of the earnings attributable to the minority partner’s interest in GPIP. During the nine months ended September 30, 2018 , the Company recognized Income Tax Expense of $41.4 million on Income before Income Taxes and Equity Income of Unconsolidated Entity of $271.1 million . The effective tax rate for the nine months ended September 30, 2018 is lower than the statutory rate primarily due to the tax effect of income attributable to noncontrolling interests as well as the mix and levels of earnings between foreign and domestic tax jurisdictions. In addition, during the nine months ended September 30, 2018 , the Company recorded discrete benefits of approximately $4 million , $11 million and $2 million associated with the indirect impacts of the NACP Combination, an adjustment to the estimated tax effects of the Tax Cuts and Jobs Act (“the Act”) and the release of a valuation allowance against the net deferred tax assets of the Company’s wholly-owned subsidiary in France, respectively. As disclosed in the Company’s financial statements in “ Note 8 - Income Taxes ” of the Notes to the Consolidated Financial Statements of the Company’s 2017 Annual Report on Form 10-K, the Company recorded provisional amounts in its 2017 financial statements to reflect the federal, state and foreign impacts of The Tax Cuts and Jobs Act (“The Act”) as well as to the balance of the Company’s deferred tax assets and liabilities. These amounts remain provisional and subject to the Securities and Exchange Commission's Staff Accountant Bulletin 118 as of September 30, 2018 . The Company recorded an additional tax benefit of approximately $11 million during the nine months ended September 30, 2018 related to the one-time transition tax on earnings of certain foreign subsidiaries. The estimate still remains provisional as the Company is still analyzing certain provisions of The Act and guidance issued by Treasury and the Internal Revenue Service associated with the one-time transition tax. The Company will file its 2017 U.S. federal income tax return reflecting the one-time transition tax during the fourth quarter of 2018. No other changes to the provisional amounts recorded in the 2017 financial statements were made during the nine months ended September 30, 2018 . During the three months ended September 30, 2018, the Company assessed the need to maintain a valuation allowance on the net deferred tax assets of one of its foreign subsidiaries in France and, based on new evidence, has determined that it is more likely than not that the net deferred tax assets will be realized through the generation of future taxable income. Appropriate consideration was given to all available evidence, both positive and negative, in assessing the need for a valuation allowance. The Company concluded that the net deferred tax assets would be realized in future years and recorded a discrete benefit during the three months ended September 30, 2018 of approximately $2 million . During the nine months ended September 30, 2017 , the Company recognized Income Tax Expense of $67.1 million on Income before Income Taxes and Equity Income of Unconsolidated Entity of $192.1 million . The effective tax rate for the nine months ended September 30, 2017 was lower than the statutory rate due to the mix and levels of earnings between foreign and domestic tax jurisdictions. In addition, the Company recorded a discrete benefit of approximately $3 million during the nine months ended September 30, 2017, of which approximately $2 million related to the excess benefit associated with share based payments to employees that vested during the period in accordance with the guidance in ASU No. 2016-09, Compensation-Stock Compensation (Topic 718) , which requires entities to recognize all income tax effects of excess tax benefits and tax deficiencies in the income statement during the period in which the awards vest or are settled. In addition, approximately $1 million was recorded as a result of statutory rate changes, income tax credits and other discrete items. As of December 31, 2017 , the Company had approximately $327 million of Net Operating Losses (“NOLs”) for U.S. federal income tax purposes which may be used to offset future taxable income. Based on these NOLs and other tax benefits, the Company does not expect to be a meaningful U.S. federal cash taxpayer until 2021.

Commitments and Contingencies Disclosure [Abstract]
Environmental and Legal Matters	ENVIRONMENTAL AND LEGAL MATTERS Environmental Matters The Company is subject to a broad range of foreign, federal, state and local environmental, health and safety laws and regulations, including those governing discharges to air, soil and water, the management, treatment and disposal of hazardous substances, solid waste and hazardous wastes, the investigation and remediation of contamination resulting from historical site operations and releases of hazardous substances, and the health and safety of employees. Compliance initiatives could result in significant costs, which could negatively impact the Company’s consolidated financial position, results of operations or cash flows. Any failure to comply with environmental or health and safety laws and regulations or any permits and authorizations required thereunder could subject the Company to fines, corrective action or other sanctions. Some of the Company’s current and former facilities are the subject of environmental investigations and remediations resulting from historic operations and the release of hazardous substances or other constituents. Some current and former facilities have a history of industrial usage for which investigation and remediation obligations may be imposed in the future or for which indemnification claims may be asserted against the Company. Also, closures or sales of facilities may necessitate investigation and may result in remediation activities at those facilities. The Company has established reserves for those facilities or issues where a liability is probable and the costs are reasonably estimable. The Company believes that the amounts accrued for its loss contingencies, and the reasonably possible loss beyond the amounts accrued, are not material to the Company’s consolidated financial position, results of operations or cash flows. The Company cannot estimate with certainty other future compliance, investigation or remediation costs. Some costs relating to historic usage that the Company considers to be reasonably possible of resulting in liability are not quantifiable at this time. The Company will continue to monitor environmental issues at each of its facilities, as well as regulatory developments, and will revise its accruals, estimates and disclosures relating to past, present and future operations, as additional information is obtained. Legal Matters The Company is a party to a number of lawsuits arising in the ordinary conduct of its business. Although the timing and outcome of these lawsuits cannot be predicted with certainty, the Company does not believe that disposition of these lawsuits will have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

Segment Information	SEGMENT INFORMATION The Company reports its results in three reportable segments as follows: Paperboard Mills includes the eight North American paperboard mills which produce primarily CUK, CRB, and SBS, which is consumed internally to produce paperboard packaging for the Americas and Europe Paperboard Packaging segments. The remaining paperboard is sold externally to a wide variety of paperboard packaging converters and brokers. The Paperboard Mills segment Net Sales represent the sale of paperboard only to external customers. The effect of intercompany transfers to the paperboard packaging segments has been eliminated from the Paperboard Mills segment to reflect the economics of the integration of these segments. Americas Paperboard Packaging includes paperboard packaging folding cartons and cups, lids and food containers sold primarily to consumer packaged goods and foodservice companies serving the food, beverage, and consumer product markets in the Americas. Europe Paperboard Packaging includes paperboard packaging folding cartons and cups, lids and food containers sold primarily to consumer packaged goods companies serving the food, beverage and consumer product markets in Europe. The Company allocates certain mill and corporate costs to the reportable segments to appropriately represent the economics of these segments.

General Information (Policies)

General Information (Policies)	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Consolidation	The Company’s Condensed Consolidated Financial Statements include all subsidiaries in which the Company has the ability to exercise direct or indirect control over operating and financial policies. Intercompany transactions and balances are eliminated in consolidation.
Basis of Accounting	In the Company’s opinion, the accompanying Condensed Consolidated Financial Statements contain all normal recurring adjustments necessary to present fairly the financial position, results of operations and cash flows for the interim periods. The Company’s year end Condensed Consolidated Balance Sheet data was derived from audited financial statements. The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with instructions to Form 10-Q and Rule 10-01 of Regulation S-X and do not include all the information required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for complete financial statements. Therefore, these Condensed Consolidated Financial Statements should be read in conjunction with GPHC’s Form 10-K for the year ended December 31, 2017 .
Use of Estimates	In addition, the preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates and changes in these estimates are recorded when known.
Revenue Recognition	The Company has two primary activities from which it generates revenue from contracts with customers, and revenue is disaggregated primarily by geography and type of activity as further explained in " Note 10-Segments. " All reportable segments and the Australia and Pacific Rim operating segments recognize revenue under the same method, allocate transaction price using similar methods, and have similar economic factors impacting the uncertainty of revenue and related cash flows. Revenue is recognized on the Company's annual and multi-year supply contracts when the Company satisfies the performance obligation by transferring control over the product or service to a customer, which is generally based on shipping terms and passage of title under the point-in-time method of recognition. For the three months ended September 30, 2018 and 2017, the Company recognized $1,525.7 million and $1,132.0 million , respectively, of revenue from contracts with customers. For the nine months ended September 30, 2018 and 2017 , the Company recognized $4,502.7 million and $3,277.8 million , respectively, of revenue from contracts with customers. The transaction price allocated to each performance obligation consists of the stand alone selling price, estimates of rebates and other sales or contract renewal incentives, and cash discounts and sales returns ("Variable Consideration"). Estimates are made for Variable Consideration based on contract terms and historical experience of actual results and are applied to the performance obligations as they are settled. Purchases by the Company’s principal customers are manufactured and shipped with minimal lead time, therefore performance obligations are generally settled shortly after manufacturing and shipment. The Company's contract assets consist primarily of contract renewal incentive payments to customers which are amortized over the period in which performance obligations related to the contract renewal are satisfied.
Accounting Standards Adopted and Not Yet Adopted	Adoption of New Accounting Standards Effective January 1, 2018, the Company adopted Accounting Standards Update ("ASU") No. 2017-09, Compensation - Stock Compensation (Topic 718); Scope of Modification Accounting. The amendments in this ASU provide guidance that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. If the value, vesting conditions or classification of the award changes, modification accounting will apply. The adoption of this standard did not have a material impact on the Company’s financial position, results of operations and cash flows. Effective January 1, 2018, the Company adopted ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715); Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The amendments in this ASU require the service cost component of net periodic benefit cost be reported in the same income statement line or lines as other compensation costs for employees. The other components of net periodic benefit cost are required to be reported separately from service costs and outside a subtotal of income from operations. Only the service cost component is eligible for capitalization. The adoption of this ASU was applied retrospectively for the reclassification of net periodic benefit expense, excluding service costs, in the Condensed Consolidated Statement of Operations. The adoption of this ASU did not have a material impact on the Company’s financial position, results of operations and cash flows. Effective January 1, 2018, the Company adopted ASU No. 2017-01, Business Combinations (Topic 805); Clarifying the Definition of a Business . The amendments in this ASU provide guidance in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. This ASU was adopted prospectively and did not have a material impact on the Company’s financial position, results of operations and cash flows. Effective January 1, 2018, the Company adopted ASU No. 2016-15, Statement of Cash Flows (Topic 230); Classification of Certain Cash Receipts and Cash Payments . The amendments in this ASU provide guidance on how certain cash receipts and payments should be presented in the statement of cash flows and was applied retrospectively. This ASU requires the Company to classify consideration received for beneficial interest obtained for selling trade receivables as investing instead of operating activities. The retrospective impact on the Company's consolidated statement of cash flows for the nine months ended September 30, 2017 was a $424.8 million decrease to cash provided by operating activities and a corresponding increase to cash provided by investing activities. Effective January 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), using the modified retrospective approach. Adoption of ASU No. 2014-09 requires that an entity recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company considered whether the adoption may require acceleration of revenue for products produced by the Company without an alternative use and when the Company would have a legally enforceable right of payment. The Company has determined that it does not have an enforceable right of payment for products produced but not yet shipped and recognizes all revenue under the point in time method. The adoption of ASU No. 2014-09 did not have a material impact on the Company's financial position, results of operations and cash flows. Accounting Standards Not Yet Adopted In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815); Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU better align the risk management activities and financial reporting for these hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company does not expect the adoption of this standard to have a material impact on the Company’s financial position, results of operations and cash flows. In January 2017, the FASB issued ASU No. 2017-04 Intangibles - Goodwill and Other (Topic 350); Simplifying the Test for Goodwill Impairment which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 of the goodwill impairment model. Step 2 measures a goodwill impairment loss by comparing the implied value of a reporting unit’s goodwill with the carrying amount of that goodwill. An entity would recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized is limited to the amount of goodwill allocated to that reporting unit. The guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for any impairment tests performed after January 1, 2017. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The amendments in this ASU require an entity to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures about leasing arrangements. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The updated guidance allows a modified retrospective adoption, which the Company plans to adopt. The Company has formed an implementation team including representatives from finance, information technology and supply chain to assist in the implementation of this standard. A software solution has been determined, and is being populated as the Company is gathering information on all of its leases.
