Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Interim Presentation	Basis of Interim Presentation In the opinion of the management of Sonoco Products Company (the “Company” or “Sonoco”), the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of only normal recurring adjustments, unless otherwise stated) necessary to state fairly the consolidated financial position, results of operations and cash flows for the interim periods reported herein. Operating results for the three months ended March 31, 2019, are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018.With respect to the unaudited condensed consolidated financial information of the Company for the three-month periods ended March 31, 2019 and April 1, 2018 included in this Form 10-Q, PricewaterhouseCoopers LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report dated May 1, 2019 appearing herein, states that they did not audit and they do not express an opinion on that unaudited financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their report on the unaudited financial information because that report is not a “report” or a “part” of a registration statement prepared or certified by PricewaterhouseCoopers LLP within the meaning of Sections 7 and 11 of the Act.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In December 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-16 “Derivatives and Hedging: Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes,” which allows the use of the SOFR and OIS rate as benchmark rates after the Federal Reserve started publishing such daily rate on April 3, 2018. The Company adopted the standard effective January 1, 2019 using the prospective basis. The adoption did not have a material effect on the consolidated financial statements. In January 2016, the FASB issued ASU 2016-02, "Leases" (“ASU 2016-02”) requiring lessees to recognize on the balance sheet a right-of-use asset and lease liability for all long-term leases and requiring disclosure of key information about leasing arrangements in order to increase transparency and comparability among organizations. The accounting for lessors does not fundamentally change except for changes to conform and align guidance to the lessee guidance and the revenue recognition standard adopted in 2018. The Company established a cross-functional team to implement certain software solutions as part of its newly integrated enterprise-wide lease management system. The implementation plan included developing business processes, accounting systems, and internal controls to ensure the Company's compliance with reporting and disclosure requirements of the new standard. The Company elected the package of practical expedients permitted under the transition guidance within the new standard upon adoption and has made an accounting policy election to keep leases with a term of 12 months or less off of the balance sheet in accordance with ASU 2016-02’s short-term lease exemption provision. The Company is also electing the hindsight practical expedient to determine the reasonably certain lease term for existing leases and has elected to combine lease and non-lease components as a single lease component for all classes of assets. The Company adopted ASU 2016-02 as of January 1, 2019, using a modified retrospective transition method and elected to apply the optional transition approach prescribed by ASU 2018-11 which allows entities to initially apply the new leases standard at the adoption date, without adjusting comparative periods. The adoption of the ASU 2016-02 resulted in the Company recording a right of use asset impact of $336,083 and a lease liability impact of $344,362 to its consolidated balance sheet, partially offset by a cumulative effect adjustment to retained earnings of $6,771 and a $1,508 reduction to deferred tax liabilities. During the three-month period ended March 31, 2019, there have been no other newly issued nor newly applicable accounting pronouncements that have had, or are expected to have, a material impact on the Company’s financial statements. Further, at March 31, 2019, there were no other pronouncements pending adoption that are expected to have a material impact on the Company’s consolidated financial statements.

Acquisitions

Business Combinations [Abstract]
Acquisitions	Acquisitions The Company completed the acquisition of the remaining 70 percent interest in Conitex Sonoco (BVI), Ltd. ("Conitex Sonoco") from Texpack Investments, Inc. ("Texpack") on October 1, 2018. Concurrent with this acquisition, the Company also acquired a rigid paper facility in Spain ("Compositub") from Texpack Group Holdings B.V. Final consideration for both acquisitions was subject to a post-closing adjustment for the change in working capital to the date of closing. These adjustments were settled in February 2019 for additional cash payments to the sellers totaling $455. On April 12, 2018, the Company completed the acquisition of Highland Packaging Solutions ("Highland"). Highland manufactures thermoformed plastic packaging for fresh produce and dairy products from a single production facility in Plant City, Florida. The acquisition of Highland included a contingent purchase liability of $7,500 payable in two installments and based upon a sales metric which the Company expects to meet. The first installment of $5,000 is expected to be paid by the end of the second quarter of 2019 and the second installment of $2,500 is to be paid two years after the closing date. The liability for these two payments has been recognized in full on the Company's Condensed Consolidated Balance Sheets at March 31, 2019 and December 31,2018, with the first installment included in "Accrued expenses and other" and the second in "Other Liabilities." During the three months ended March 31, 2019, the Company continued to finalize its valuations of the assets acquired and liabilities assumed in acquisitions completed in the previous year based on new information obtained about facts and circumstances that existed as of their respective acquisition dates. As a result, the following measurement period adjustments were made to the previously disclosed provisional fair values: Conitex Sonoco Compositub Highland Trade accounts receivable $ (77) $ 203 $ — Inventories — 50 — Property, plant and equipment (199) (1,026) 1,895 Goodwill 1,971 (566) (1,895) Other intangible assets 300 1,888 — Accrued expenses and other (1,782) (138) — Other net tangible assets /(liabilities) (129) (40) — Net assets $ 84 $ 371 $ — Management is continuing to finalize its valuations of certain assets and liabilities associated with its 2018 acquisitions, including, but not limited to: inventory; property, plant and equipment; other intangible assets; and trade accounts receivable, and expects to complete its valuations within one year of the respective dates of acquisition. The Company has accounted for its acquisitions as business combinations under the acquisition method of accounting, in accordance with the business combinations subtopic of the Accounting Standards Codification and has included their results of operations in the Company's Condensed Consolidated Statements of Income from their respective dates of acquisition.

Equity [Abstract]
Shareholders' Equity	Shareholders' Equity Earnings per Share The following table sets forth the computation of basic and diluted earnings per share: Three Months Ended March 31, 2019 April 1, 2018 Numerator: Net income attributable to Sonoco $ 73,663 $ 74,055 Denominator: Weighted average common shares outstanding: Basic 100,640 100,396 Dilutive effect of stock-based compensation 432 500 Diluted 101,072 100,896 Net income attributable to Sonoco per common share: Basic $ 0.73 $ 0.74 Diluted $ 0.73 $ 0.73 Cash dividends $ 0.41 $ 0.39 Potentially dilutive securities are calculated in accordance with the treasury stock method, which assumes the proceeds from the exercise of all dilutive stock appreciation rights (SARs) are used to repurchase the Company’s common stock. Certain SARs are not dilutive because either the exercise price is greater than the average market price of the stock during the reporting period or assumed repurchases from proceeds from the exercise of the SARs were antidilutive. These SARs may become dilutive in the future if the market price of the Company's common stock appreciates. The average numbers of SARs that were not dilutive and, therefore, not included in the computation of diluted earnings per share during the three month periods ended March 31, 2019 and April 1, 2018 were as follows: Three Months Ended March 31, 2019 April 1, 2018 Anti-dilutive stock appreciation rights 305 738 No adjustments were made to net income attributable to Sonoco in the computations of earnings per share. Stock Repurchases On February 10, 2016, the Company’s Board of Directors authorized the repurchase of up to 5,000 shares of the Company's common stock. A total of 2,030 were purchased in 2016. No shares were repurchased under this authorization during 2017, 2018, or during the three months ended March 31, 2019. Accordingly, a total of 2,970 shares remain available for repurchase at March 31, 2019. The Company frequently repurchases shares of its common stock to satisfy employee tax withholding obligations in association with certain share-based compensation awards. These repurchases, which are not part of a publicly announced plan or program, totaled 133 shares in the three months ended March 31, 2019 at a cost of $7,395, and 78 shares in the three months ended April 1, 2018 at a cost of $4,088. Dividend Declarations On February 13, 2019, the Board of Directors declared a regular quarterly dividend of $0.41 per share. This dividend was paid on March 8, 2019 to all shareholders of record as of February 27, 2019. On April 17, 2019, the Board of Directors declared a regular quar terly dividend of $0.43 per share. This dividend is payable on June 10, 2019 to all shareholders of record as of May 10, 2019.

Restructuring and Related Activities [Abstract]
Restructuring and Asset Impairment	Restructuring and Asset Impairment The Company has engaged in a number of restructuring actions over the past several years. Actions initiated in 2019 and 2018 are reported as “2019 Actions” and “2018 Actions,” respectively. Actions initiated prior to 2018, all of which were substantially complete at March 31, 2019, are reported as “2017 and Earlier Actions.” Following are the total restructuring and asset impairment charges, net of adjustments, recognized by the Company during the periods presented: Three Months Ended March 31, 2019 April 1, 2018 Restructuring/Asset impairment: 2019 Actions $ 6,389 $ — 2018 Actions 4,046 2,207 2017 and Earlier Actions 237 856 Restructuring/Asset impairment charges 10,672 3,063 Income tax benefit (2,638) (685) Less: Costs attributable to noncontrolling interests, net of tax (69) (5) Restructuring/asset impairment charges attributable to Sonoco, net of tax $ 7,965 $ 2,373 Pre-tax restructuring and asset impairment charges are included in “Restructuring/Asset impairment charges” in the Condensed Consolidated Statements of Income. When recognizable in accordance with GAAP, the Company expects to recognize future additional charges totaling approximately $5,100 in connection with previously announced restructuring actions. The Company believes that the majority of these charges will be incurred and paid by the end of 2019. The Company continually evaluates its cost structure, including its manufacturing capacity, and additional restructuring actions are likely to be undertaken. 2019 Actions During 2019, the Company announced the elimination of a forming film production line at a flexible packaging facility in the United States, and initiated the closure of a composite can and injection molding facility in Germany (both part of the Consumer Packaging segment).

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill A summary of the changes in goodwill by segment for the three months ended March 31, 2019 is as follows: Consumer Display Paper and Protective Total Goodwill at December 31, 2018 $ 617,332 $ 203,414 $ 256,947 $ 231,474 $ 1,309,167 Foreign currency translation (690) — (929) 108 (1,511) Other (2,461) — 1,971 — (490) Goodwill at March 31, 2019 $ 614,181 $ 203,414 $ 257,989 $ 231,582 $ 1,307,166 Measurement period adjustments made in the first three months of 2019 to finalize the fair values of the assets acquired and the liabilities assumed in the 2018 acquisitions of Compositub, Highland, and Conitex Sonoco resulted in increases/(decreases) in goodwill of $(566), $(1,895) and $1,971, respectively. These adjustments are reflected above in "Other." See Note 3 for additional information. The Company assesses goodwill for impairment annually and from time to time when warranted by the facts and circumstances surrounding individual reporting units or the Company as a whole. The Company completed its most recent annual goodwill impairment testing during the third quarter of 2018. As part of this testing, the Company analyzed certain qualitative and quantitative factors in determining goodwill impairment. The Company's assessments reflected a number of significant management assumptions and estimates including discount rates, and the Company's forecast of sales volumes and prices, new business, profit margins, income taxes, capital expenditures and changes in working capital requirements. Changes in these assumptions could materially impact the Company's conclusions. Based on its assessments, the Company concluded that there was no impairment of goodwill for any of its reporting units. Although no reporting units failed the assessments noted above, in management’s opinion, the goodwill of the Display and Packaging reporting unit is at risk of impairment in the near term if operating performance does not continue to improve in line with management's expectations, or if there is a negative change in the long-term outlook for the business or in other factors such as the discount rate. Total goodwill associated with this reporting unit was $203,414 at March 31, 2019. In addition, a large portion of projected sales in the Display and Packaging reporting unit is concentrated in several major customers, the loss of any of which could impact the Company's conclusion regarding the likelihood of goodwill impairment for the unit. During the time subsequent to the annual evaluation, and at March 31, 2019, the Company considered whether any events and/or changes in circumstances had resulted in the likelihood that the goodwill of any of its reporting units may have been impaired. It is management's opinion that no such events have occurred. Other Intangible Assets A summary of other intangible assets as of March 31, 2019 and December 31, 2018 is as follows: March 31, December 31, Other Intangible Assets, gross: Patents $ 22,496 $ 22,509 Customer lists 548,443 548,038 Trade names 31,010 31,174 Proprietary technology 28,333 28,748 Land use rights 286 282 Other 2,124 2,093 Other Intangible Assets, gross $ 632,692 $ 632,844 Accumulated Amortization: Patents (10,021) (9,539) Customer lists (256,696) (246,946) Trade names (7,773) (7,413) Proprietary technology (15,818) (15,400) Land use rights (49) (48) Other (1,491) (1,461) Total Accumulated Amortization $ (291,848) $ (280,807) Other Intangible Assets, net $ 340,844 $ 352,037 Measurement period adjustments made in the first three months of 2019 to finalize the fair values of the assets acquired and the liabilities assumed in the 2018 acquisitions of Compositub and Conitex Sonoco resulted in increases in other intangible assets, primarily customer lists, of $1,888 and $300, respectively. Other intangible assets are amortized on a straight-line basis over their respective useful lives, which generally range from three Aggregate amortization expense was $12,792 and $10,202 for the three months ended March 31, 2019 and April 1, 2018, respectively. Amortization expense on other intangible assets is expected to total approximately $50,000 in 2019, $47,600 in 2020, $45,600 in 2021, $43,200 in 2022 and $38,400 in 2023.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments and Derivatives	Financial Instruments and Derivatives The following table sets forth the carrying amounts and fair values of the Company’s significant financial instruments for which the carrying amount differs from the fair value. March 31, 2019 December 31, 2018 Carrying Fair Carrying Fair Long-term debt, net of current portion $ 1,189,415 $ 1,273,699 $ 1,189,717 $ 1,270,521 The carrying value of cash and cash equivalents, short-term debt and long-term variable-rate debt approximates fair value. The fair value of long-term debt is determined based on recent trade information in the financial markets of the Company’s public debt or is determined by discounting future cash flows using interest rates available to the Company for issues with similar terms and maturities. It is considered a Level 2 fair value measurement. Cash Flow Hedges At March 31, 2019 and December 31, 2018, the Company had derivative financial instruments outstanding to hedge anticipated transactions and certain asset and liability related cash flows. These contracts, which have maturities ranging to December 2020, qualify as cash flow hedges under U.S. GAAP. For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings and is presented in the same income statement line item as the earnings effect of the hedged item. Commodity Cash Flow Hedges The Company has entered into certain derivative contracts to manage the cost of anticipated purchases of natural gas and aluminum. At March 31, 2019, natural gas swaps covering approximately 6.0 million MMBTUs were outstanding. These contracts represent approximately 74% and 42% of anticipated U.S. and Canadian usage for the remainder of 2019 and 2020, respectively. Additionally, the Company had swap contracts covering 3,062 metric tons of aluminum, representing approximately 51% of anticipated usage for the remainder of 2019. The fair values of the Company’s commodity cash flow hedges netted to a loss position of $(914) and $(1,571) at March 31, 2019 and December 31, 2018 respectively. The amount of the loss included in Accumulated Other Comprehensive Loss at March 31, 2019, that is expected to be reclassified to the income statement during the next twelve months is $(918). Foreign Currency Cash Flow Hedges The Company has entered into forward contracts to hedge certain anticipated foreign currency denominated sales, purchases, and capital spending forecast to occur in 2019. The net positions of these contracts at March 31, 2019 were as follows (in thousands): Currency Action Quantity Colombian peso purchase 12,928,059 Mexican peso purchase 341,547 Polish zloty purchase 50,222 Canadian dollar purchase 46,690 Czech koruna purchase 34,652 Turkish lira purchase 4,917 British pound purchase 1,133 Swedish krona sell (2,180) Euro sell (13,542) Russian ruble sell (83,981) The fair value of foreign currency cash flow hedges related to forecasted sales and purchases netted to a gain position of $155 at March 31, 2019 and a loss position of $(1,624) at December 31, 2018. Gains of $155 are expected to be reclassified from accumulated other comprehensive income to the income statement during the next twelve months. I n addition, the Company has entered into forward contracts to hedge certain foreign currency cash flow transactions related to construction in progress. As of March 31, 2019 and at December 31, 2018, the net position of these contracts were $(57) and $(88), respectively. During the three months ended March 31, 2019, losses from these hedges totaling $(45) were reclassified from accumulated other comprehensive income and included in the carrying value of the related fixed assets acquired. Losses of $(57) are expected to be reclassified from accumulated other comprehensive income and included in the carrying value of the related fixed assets acquired during the next twelve months. Other Derivatives The Company routinely enters into forward contracts or swaps to economically hedge the currency exposure of intercompany debt and existing foreign currency denominated receivables and payables. The Company does not apply hedge accounting treatment under ASC 815 for these instruments. As such, changes in fair value are recorded directly to income and expense in the periods that they occur. The net positions of these contracts at March 31, 2019, were as follows (in thousands): Currency Action Quantity Colombian peso purchase 9,199,944 Mexican peso purchase 420,776 Canadian dollar purchase 21,475 South African rand sell (8,261) The fair value of the Company’s other derivatives was a loss position of $(164) and a gain position of $166 at March 31, 2019 and December 31, 2018, respectively. The following table sets forth the location and fair values of the Company’s derivative instruments at March 31, 2019 and December 31, 2018: Description Balance Sheet Location March 31, 2019 December 31, 2018 Derivatives designated as hedging instruments: Commodity Contracts Prepaid expenses $ 144 $ 282 Commodity Contracts Other assets $ 95 $ — Commodity Contracts Accrued expenses and other $ (1,153) $ (1,843) Commodity Contracts Other liabilities $ — $ (10) Foreign Exchange Contracts Prepaid expenses $ 1,119 $ 770 Foreign Exchange Contracts Accrued expenses and other $ (1,021) $ (2,482) Derivatives not designated as hedging instruments: Foreign Exchange Contracts Prepaid expenses $ — $ 727 Foreign Exchange Contracts Accrued expenses and other $ (164) $ (561) While certain of the Company’s derivative contract arrangements with its counterparties provide for the ability to settle contracts on a net basis, the Company reports its derivative positions on a gross basis.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or liability. A three-tier fair value hierarchy is used to prioritize the inputs in measuring fair value as follows: Level 1 – Observable inputs such as quoted market prices in active markets; Level 2 – Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3 – Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions. The following table sets forth information regarding the Company’s financial assets and financial liabilities, excluding retirement and postretirement plan assets, measured at fair value on a recurring basis: Description March 31, 2019 Assets measured Level 1 Level 2 Level 3 Hedge derivatives, net: Commodity contracts $ (914) $ — $ — $ (914) $ — Foreign exchange contracts $ 155 $ — $ — $ 155 $ — Non-hedge derivatives, net: Foreign exchange contracts $ (164) $ — $ — $ (164) $ — Deferred compensation plan assets $ 286 $ — $ 286 $ — $ — Description December 31, 2018 Assets measured Level 1 Level 2 Level 3 Hedge derivatives, net: Commodity contracts $ (1,571) $ — $ — $ (1,571) $ — Foreign exchange contracts $ (1,712) $ — $ — $ (1,712) $ — Non-hedge derivatives, net: Foreign exchange contracts $ 166 $ — $ — $ 166 $ — Deferred compensation plan assets $ 260 $ — $ 260 $ — $ — As discussed in Note 8, the Company uses derivatives to mitigate the effect of raw material and energy cost fluctuations, foreign currency fluctuations and, from time to time, interest rate movements. Fair value measurements for the Company’s derivatives are classified under Level 2 because such measurements are estimated based on observable inputs such as interest rates, yield curves, spot and future commodity prices and spot and future exchange rates. Certain deferred compensation plan liabilities are funded by assets invested in various exchange traded mutual funds. These assets are measured using quoted prices in accessible active markets for identical assets. The Company does not currently have any non-financial assets or liabilities that are recognized or disclosed at fair value on a recurring basis. None of the Company’s financial assets or liabilities are measured at fair value using significant unobservable inputs. There were no transfers in or out of Level 1 or Level 2 fair value measurements during the three-month periods ended March 31, 2019.

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans Retirement Plans and Retiree Health and Life Insurance Plans The Company provides non-contributory defined benefit pension plans to certain of its employees in the United States and certain of its employees in Mexico and Belgium. The Company also sponsors contributory defined benefit pension plans covering the majority of its employees in the United Kingdom, Canada, and the Netherlands. In addition, the Company provides postretirement healthcare and life insurance benefits to a limited number of its retirees and their dependents in the United States and Canada, based on certain age and/or service eligibility requirements. The Company froze participation in its U.S. qualified defined benefit pension plan for newly hired salaried and non-union hourly employees effective December 31, 2003. To replace this benefit, the Company provides non-union U.S. employees hired on or after January 1, 2004, with an annual contribution, called the Sonoco Retirement Contribution (SRC), to their participant accounts in the Sonoco Retirement and Savings Plan. The SRC is equal to 4% of the participant's eligible pay plus 4% of eligible pay in excess of the social security wage base. Also eligible for the SRC are former participants of the U.S. qualified defined benefit pension plan who elected to transfer out of that plan under a one-time option effective January 1, 2010. On February 4, 2009, the U.S. qualified defined benefit pension plan was amended to freeze plan benefits for all active, non-union participants effective December 31, 2018. Remaining active participants in the U.S. qualified plan became eligible for SRC contributions effective January 1, 2019. The components of net periodic benefit cost include the following: Three Months Ended March 31, 2019 April 1, 2018 Retirement Plans Service cost $ 941 $ 4,672 Interest cost 14,943 13,978 Expected return on plan assets (19,097) (23,209) Amortization of prior service cost 214 249 Amortization of net actuarial loss 9,034 9,420 Effect of settlement loss 1,322 — Net periodic benefit cost $ 7,357 $ 5,110 Retiree Health and Life Insurance Plans Service cost $ 74 $ 79 Interest cost 118 111 Expected return on plan assets (177) (472) Amortization of prior service credit (123) (126) Amortization of net actuarial gain (193) (242) Net periodic benefit income $ (301) $ (650) The Company made aggregate contributions of $2,780 and $4,573 to its defined benefit retirement and retiree health and life insurance plans during the three months ended March 31, 2019 and April 1, 2018, respectively. Although no contributions are required to be made to the Company's U.S. qualified pension plans in 2019, the Company is considering various options for de-risking these plans which could include additional, voluntary contributions in 2019 and reallocation of the assets held by the plans to a more conservative mix of fixed income and equity securities. Excluding the potential voluntary contributions, the Company expects to make additional aggregate contributions of approximately $13,500 to its defined benefit retirement and retiree health and life insurance plans over the remainder of 2019. The Company recognized settlement charges totaling $1,322 during the three months ended March 31, 2019 resulting from payments made to certain participants of the Company's Canadian pension plan who elected the lump sum option of distribution upon retirement. There were no settlement losses during the same period of the prior year. Sonoco Retirement Contribution (SRC)

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate for the three-month periods ending March 31, 2019 and April 1, 2018 was 23.7% and 24.1%, respectively. The rate for the three-month period ending March 31, 2019 varied from the U.S. statutory rate due primarily to the unfavorable effect of certain international operations that were subject to tax rates generally higher than the U.S. tax rate, as well as the effect of state income taxes. The rate for the three-month period ending April 1, 2018 varied from the U.S. statutory rate due primarily to the effect of the Global Intangible Low Taxed Income (GILTI) tax as well as the effect of state income taxes. The Company and/or its subsidiaries file federal, state and local income tax returns in the United States and various foreign jurisdictions. The Company is currently under audit for the 2012 and 2013 tax years and has entered the appeals process with the Internal Revenue Service. Other than the aforementioned audit, with few exceptions, the Company is no longer subject to income tax examinations by tax authorities for years prior to 2015. The Company’s reserve for uncertain tax benefits has increased by approximately $100 since December 31, 2018, due primarily to an increase in reserves related to existing uncertain tax positions. The Company believes that it is reasonably possible that the amount reserved for unrecognized tax benefits at March 31, 2019 will decrease by approximately $2,500 over the next twelve months. This change includes the anticipated increase in reserves related to existing positions offset by settlements of issues currently under examination and the release of existing reserves due to the expiration of the statute of limitations. Although the Company’s estimate for the potential outcome for any uncertain tax issue is highly judgmental, management believes that any reasonably foreseeable outcomes related to these matters have been adequately provided for. However, future results may include favorable or unfavorable adjustments to estimated tax liabilities in the period the assessments are made or resolved or when statutes of limitation on potential assessments expire. Additionally, the jurisdictions in which earnings or deductions are realized may differ from current estimates. As a result, the Company’s effective tax rate may fluctuate significantly on a quarterly basis. The Company has operations and pays taxes in many countries outside of the U.S. and taxes on those earnings are subject to varying rates. The Company is not dependent upon the favorable benefit of any one jurisdiction to an extent that the loss of such benefit would have a material effect on the Company’s overall effective tax rate. As previously disclosed, the Company received a draft Notice of Proposed Adjustment (“NOPA”) from the Internal Revenue Service (IRS) in February 2017 proposing an adjustment to income for the 2013 tax year based on the IRS's recharacterization of a distribution of an intercompany note made in 2012, and the subsequent repayment of the note over the course of 2013, as if it were a cash distribution made in 2013. In March 2017, the Company received a draft NOPA proposing penalties of $18,000 associated with the IRS’s recharacterization, as well as an Information Document Request (“IDR”) requesting the Company’s analysis of why such penalties should not apply. The Company responded to this IDR in April 2017. On October 5, 2017, the Company received two revised draft NOPAs proposing the same adjustments and penalties as in the prior NOPAs. On November 14, 2017, the Company received two final NOPAs proposing the same

Leases [Abstract]
Leases	Leases The Company routinely enters into leasing arrangements for real estate (including manufacturing facilities, office space, warehouses, and packaging centers), transportation equipment (automobiles, forklifts, and trailers), and office equipment (copiers and postage machines). The assessment of the certainty associated with the exercise of various lease renewal, termination, and purchase options included in the Company's lease contracts is at the Company's sole discretion. Most real estate leases, in particular, include one or more options to renew, with renewal terms that can extend the lease term from one As the implicit rate in the Company's leases is not readily determinable, the Company calculates its right of use lease liabilities using discount rates based upon the Company’s incremental secured borrowing rate, which contemplates and reflects a particular geographical region’s interest rate for the leases active within that region of the Company’s global operations. The Company further utilizes a portfolio approach by assigning a “short” rate to contracts with lease terms of 10 years or less and a “long” rate for contracts greater than 10 years. See Note 2 for further information regarding the Company's adoption of ASU 2016-02, "Leases." The following table sets forth the balance sheet location and values of the Company’s lease assets and lease liabilities at March 31, 2019: Classification Balance Sheet Location March 31, 2019 Lease Assets Operating lease assets Right of Use Asset - Operating Leases $ 308,166 Finance lease assets Other Assets 22,122 Total lease assets 330,288 Lease Liabilities Current operating lease liabilities Accrued expenses and other 54,979 Current finance lease liabilities Notes payable and current portion of debt 9,684 Total current lease liabilities 64,663 Noncurrent operating lease liabilities Noncurrent Operating Lease Liabilities 262,663 Noncurrent finance lease liabilities Long-term Debt, Net of Current Portion 11,472 Total noncurrent lease liabilities 274,135 Total lease liabilities $ 338,798 As of March 31, 2019, the Company has entered into additional leases that have not yet commenced. The associated contracts include payments over the respective lease terms totaling $1,789, which are not reflected in the Company's liabilities recorded as of March 31, 2019. These leases will commence during fiscal year 2019 with lease terms ranging from 3 years to 6.4 years. Certain of the Company’s leases include variable costs. Variable costs include lease payments that were volume or usage-driven in accordance with the use of the underlying asset, and also non-lease components that were incurred based upon actual terms rather than contractually fixed amounts. In addition, variable costs are incurred for lease payments that are indexed to a change in rate or index. Because the right of use asset recorded on the balance sheet was determined based upon factors considered at the commencement date, subsequent changes in the rate or index that were not contemplated in the right of use asset balances recorded on the balance sheet result in variable expenses being incurred when paid during the lease term.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company has rebate agreements with certain customers. These rebates are recorded as reductions of sales and are accrued using sales data and rebate percentages specific to each customer agreement. Accrued customer rebates are included in "Accrued expenses and other" in the Company's Condensed Consolidated Balance Sheets. Payment terms under the Company's arrangements are short term in nature, generally no longer than 120 days. The Company does provide prompt payment discounts to certain customers if invoices are paid within a predetermined period. Prompt payment discounts are treated as a reduction of revenue and are determinable within a short period of the sale. The following table sets forth information about receivables, contract assets and liabilities from contracts with customers. The balances of the contract assets and liabilities are located in "Other receivables" and "Accrued expenses and other" on the Condensed Consolidated Balance Sheets. March 31, 2019 December 31, 2018 Contract Assets $ 51,332 $ 48,786 Contract Liabilities $ (14,757) $ (18,533) Significant changes in the contract assets and liabilities balances during the period were as follows: March 31, 2019 December 31, 2018 Contract Contract Contract Contract Beginning Balance $ 48,786 $ (18,533) $ 45,877 $ (17,736) Revenue deferred or rebates accrued — (6,928) — (19,730) Recognized as revenue 2,098 1,652 Rebates paid to customers — 8,606 — 17,281 Increases due to rights to consideration for customer specific goods produced, but not billed during the period 51,332 — 48,786 — Transferred to receivables from contract assets recognized at the beginning of the period (48,786) — (45,877) — Increase as a result of cumulative catch-up arising from changes in the estimate of completion, excluding amounts transferred to receivables during the period — — — — Impairment of contract asset — — — — Ending Balance $ 51,332 $ (14,757) $ 48,786 $ (18,533) Contract assets and liabilities are generally short in duration given the nature of products produced by the Company. Contract assets represents goods produced without alternative use for which the Company is entitled to payment with margin prior to shipment. Upon shipment, the Company is entitled to bill the customer, and therefore amounts included in contract assets will be reduced with the recording of an account receivable as they represent an unconditional right to payment. Contract liabilities represent revenue deferred due to pricing mechanisms utilized by the Company in certain multi-year arrangements, volume rebates, and receipts of advanced payments. For multi-year arrangements with pricing mechanisms, the Company will generally defer revenue during the initial term of the arrangement, and will release the deferral over the back half of the contract term. The Company's reportable segments are aligned by product nature as disclosed in Note 14. The following tables set forth information about revenue disaggregated by primary geographic regions, and timing of revenue recognition for the three-month periods ended March 31, 2019 and April 1, 2018.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Pursuant to U.S. GAAP, accruals for estimated losses are recorded at the time information becomes available indicating that losses are probable and that the amounts are reasonably estimable. As is the case with other companies in similar industries, the Company faces exposure from actual or potential claims and legal proceedings from a variety of sources. Some of these exposures, as discussed below, have the potential to be material. Environmental Matters The Company is subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which it operates. Spartanburg In connection with its acquisition of Tegrant in November 2011, the Company identified potential environmental contamination at a site in Spartanburg, South Carolina. The total remediation cost of the Spartanburg site was estimated to be $17,400 at the time of acquisition and an accrual in this amount was recorded on Tegrant’s opening balance sheet. Since the acquisition, the Company has spent a total of $1,480 on remediation of the Spartanburg site. During previous years, the Company has increased its reserves for this site by a total of $17 in order to reflect its best estimate of what it is likely to pay in order to complete the remediation. At March 31, 2019 and December 31, 2018, the Company's accrual for environmental contingencies related to the Spartanburg site totaled $15,937 and $15,964, respectively. The Company cannot currently estimate its potential liability, damages or range of potential loss, if any, beyond the amounts accrued with respect to this exposure. However, the Company does not believe that the resolution of this matter has a reasonable possibility of having a material adverse effect on the Company's financial statements. Other environmental matters The Company has been named as a potentially responsible party at several other environmentally contaminated sites. All of the sites are also the responsibility of other parties. The potential remediation liabilities are shared with such other parties, and, in most cases, the Company’s share, if any, cannot be reasonably estimated at the current time. However, the Company does not believe that the resolution of these matters has a reasonable possibility of having a material adverse effect on the Company's financial statements. At March 31, 2019 and December 31, 2018, the Company's accrual for these other sites totaled $4,059 and $4,136, respectively. Summary As of March 31, 2019 and December 31, 2018, the Company (and its subsidiaries) had accrued $19,996 and $20,100, respectively, related to environmental contingencies. These accruals are included in “Accrued expenses and other” on the Company’s Condensed Consolidated Balance Sheets. Other Legal Matters In addition to those matters described above, the Company is subject to other various legal proceedings, claims, and litigation arising in the ordinary course of business. While the outcome of these matters could differ from management’s expectations, the Company does not believe the resolution of these matters has a reasonable possibility of having a material adverse effect on the Company’s financial statements.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	In December 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-16 “Derivatives and Hedging: Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes,” which allows the use of the SOFR and OIS rate as benchmark rates after the Federal Reserve started publishing such daily rate on April 3, 2018. The Company adopted the standard effective January 1, 2019 using the prospective basis. The adoption did not have a material effect on the consolidated financial statements. In January 2016, the FASB issued ASU 2016-02, "Leases" (“ASU 2016-02”) requiring lessees to recognize on the balance sheet a right-of-use asset and lease liability for all long-term leases and requiring disclosure of key information about leasing arrangements in order to increase transparency and comparability among organizations. The accounting for lessors does not fundamentally change except for changes to conform and align guidance to the lessee guidance and the revenue recognition standard adopted in 2018. The Company established a cross-functional team to implement certain software solutions as part of its newly integrated enterprise-wide lease management system. The implementation plan included developing business processes, accounting systems, and internal controls to ensure the Company's compliance with reporting and disclosure requirements of the new standard. The Company elected the package of practical expedients permitted under the transition guidance within the new standard upon adoption and has made an accounting policy election to keep leases with a term of 12 months or less off of the balance sheet in accordance with ASU 2016-02’s short-term lease exemption provision. The Company is also electing the hindsight practical expedient to determine the reasonably certain lease term for existing leases and has elected to combine lease and non-lease components as a single lease component for all classes of assets. The Company adopted ASU 2016-02 as of January 1, 2019, using a modified retrospective transition method and elected to apply the optional transition approach prescribed by ASU 2018-11 which allows entities to initially apply the new leases standard at the adoption date, without adjusting comparative periods. The adoption of the ASU 2016-02 resulted in the Company recording a right of use asset impact of $336,083 and a lease liability impact of $344,362 to its consolidated balance sheet, partially offset by a cumulative effect adjustment to retained earnings of $6,771 and a $1,508 reduction to deferred tax liabilities. During the three-month period ended March 31, 2019, there have been no other newly issued nor newly applicable accounting pronouncements that have had, or are expected to have, a material impact on the Company’s financial statements. Further, at March 31, 2019, there were no other pronouncements pending adoption that are expected to have a material impact on the Company’s consolidated financial statements.
Fair Value Measurements	Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or liability. A three-tier fair value hierarchy is used to prioritize the inputs in measuring fair value as follows: Level 1 – Observable inputs such as quoted market prices in active markets; Level 2 – Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3 – Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.
Commitments and Contingencies	Pursuant to U.S. GAAP, accruals for estimated losses are recorded at the time information becomes available indicating that losses are probable and that the amounts are reasonably estimable. As is the case with other companies in similar industries, the Company faces exposure from actual or potential claims and legal proceedings from a variety of sources.
