Text Block [Abstract]
Basis of Presentation	Basis of presentation The Consolidated Financial Statements include the accounts of Sonoco Products Company and its majority-owned subsidiaries (the “Company” or “Sonoco”) after elimination of intercompany accounts and transactions. Investments in affiliated companies in which the Company shares control over the financial and operating decisions, but in which the Company is not the primary beneficiary, are accounted for by the equity method of accounting. Income applicable to these equity investments is reflected in “Equity in earnings of affiliates, net of tax” in the Consolidated Statements of Income.
Estimates and Assumptions	Estimates and assumptions The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Revenue Recognition	Revenue recognition The Company records revenue when title and risk of ownership pass to the customer, and when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the sales price to the customer is fixed or determinable and when collectibility is reasonably assured. Certain judgments, such as provisions for estimates of sales returns and allowances, are required in the application of the Company’s revenue policy and, therefore, are included in the results of operations in its Consolidated Financial Statements. Shipping and handling expenses are included in “Cost of sales,” and freight charged to customers is included in “Net sales” in the Company’s Consolidated Statements of Income. 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 Consolidated Balance Sheets.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts receivable and allowance for doubtful accounts The Company’s trade accounts receivable are non-interest bearing and are recorded at the invoiced amounts. The allowance for doubtful accounts represents the Company’s best estimate of the amount of probable credit losses in existing accounts receivable. Provisions are made to the allowance for doubtful accounts at such time that collection of all or part of a trade account receivable is in question. The allowance for doubtful accounts is monitored on a regular basis and adjustments are made as needed to ensure that the account properly reflects the Company’s best estimate of uncollectible trade accounts receivable. Account balances are charged off against the allowance for doubtful accounts when the Company determines that the receivable will not be recovered.
Research and Development	Research and development Research and development costs are charged to expense as incurred and include salaries and other directly related expenses.
Restructuring and Asset Impairment	Restructuring and asset impairment Costs associated with exit or disposal activities are recognized when the liability is incurred. If assets become impaired as a result of a restructuring action, the assets are written down to fair value, less estimated costs to sell, if applicable. A number of significant estimates and assumptions are involved in the determination of fair value. The Company considers historical experience and all available information at the time the estimates are made; however, the amounts that are ultimately realized upon the sale of divested assets may differ from the estimated fair values reflected in the Company’s Consolidated Financial Statements.
Cash and Cash Equivalents	Cash and cash equivalents Cash equivalents are composed of highly liquid investments with an original maturity to the Company of three months or less when purchased. Cash equivalents are recorded at cost, which approximates market.
Inventories	Inventories Inventories are stated at the lower of cost or market. The last-in, first-out (LIFO) method is used for the valuation of certain of the Company’s domestic inventories, primarily metal, internally manufactured paper and paper purchased from third parties. The LIFO method of accounting was used to determine the carrying costs of approximately 19% and 16% of total inventories at December 31, 2015 and 2014, respectively. The remaining inventories are determined on the first-in, first-out (FIFO) method. If the FIFO method of accounting had been used for all inventories, total inventory would have been higher by $18,894 and $17,908 at December 31, 2015 and 2014, respectively.
Property, Plant and Equipment	Property, plant and equipment Plant assets represent the original cost of land, buildings and equipment, less depreciation, computed under the straight-line method over the estimated useful lives of the assets, and are reviewed for impairment whenever events indicate the carrying value may not be recoverable. Equipment lives generally range from 3 to 11 years, and buildings from 15 to 40 years. Timber resources are stated at cost. Depletion is charged to operations based on the estimated number of units of timber cut during the year.
Goodwill and Other Intangible Assets	Goodwill and other intangible assets The Company assesses its 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. In performing the impairment test, the Company uses either a qualitative evaluation or a quantitative test. The qualitative evaluation considers factors such as the macroeconomic environment, Company stock price and market capitalization movement, business strategy changes, and significant customer wins and losses. The quantitative test considers factors such as the amount by which estimated fair value exceeds current carrying value, current year operating performance as compared to prior projections, and implied fair values from comparable trading and transaction multiples. Calculated reporting unit estimated fair values reflect a number of significant management assumptions and estimates including the Company's forecast of sales volumes and prices, profit margins, income taxes, capital expenditures and changes in working capital requirements. Changes in these assumptions and/or discount rates could materially impact the estimated fair values. When the Company estimates the fair value of a reporting unit, it does so using a discounted cash flow model based on projections of future years' operating results and associated cash flows, together with comparable trading and transaction multiples. The Company's projections incorporate management's best estimates of the expected future results, which include expectations related to new business, and, where applicable, improved operating margins. Management's projections related to revenue growth and/or margin improvements arise from a combination of factors, including expectations for volume growth with existing customers, product expansion, improved price/cost, productivity gains, fixed cost leverage, improvement in general economic conditions, increased operational capacity, and customer retention. Projected future cash flows are then discounted to present value using a discount rate management believes is commensurate with the risks inherent in the cash flows. If the fair value of a reporting unit exceeds the carrying value of the reporting unit’s assets, including goodwill, there is no impairment. If not, and the carrying value of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment charge is recognized for the excess. Goodwill is not amortized. Intangible assets are amortized, usually on a straight-line basis, over their respective useful lives, which generally range from 3 to 40 years. The Company evaluates its intangible assets for impairment whenever indicators of impairment exist. The Company has no intangibles with indefinite lives.
Income Taxes	Income taxes The Company provides for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting requirements and tax laws. Assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.
Derivatives	Derivatives The Company uses derivatives to mitigate the effect of fluctuations in some of its raw material and energy costs, foreign currencies, and, from time to time, interest rates. The Company purchases commodities such as recovered paper, metal, resins and energy generally at market or at fixed prices that are established with the vendor as part of the purchase process for quantities expected to be consumed in the ordinary course of business. The Company may enter into commodity futures or swaps to manage the effect of price fluctuations. The Company may use foreign currency forward contracts and other risk management instruments to manage exposure to changes in foreign currency cash flows and the translation of monetary assets and liabilities on the Company’s consolidated financial statements. The Company is exposed to interest-rate fluctuations as a result of using debt as a source of financing for its operations. The Company may from time to time use traditional, unleveraged interest rate swaps to adjust its mix of fixed and variable rate debt to manage its exposure to interest rate movements. The Company records its derivatives as assets or liabilities on the balance sheet at fair value using published market prices or estimated values based on current price and/or rate quotes and discounted estimated cash flows. Changes in the fair value of derivatives are recognized either in net income or in other comprehensive income, depending on the designated purpose of the derivative. Amounts in accumulated other comprehensive income are reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings. It is the Company’s policy not to speculate in derivative instruments.
Reportable Segments	Reportable segments The Company identifies its reportable segments by evaluating the level of detail reviewed by the chief operating decision maker, gross profit margins, nature of products sold, nature of the production processes, type and class of customer, methods used to distribute products, and nature of the regulatory environment. Of these factors, the Company believes that the most significant are the nature of the products and the type of customers served.
Contingencies	Contingencies Pursuant to U.S. GAAP for accounting for contingencies, accruals for estimated losses are recorded at the time information becomes available indicating that losses are probable and that the amounts are reasonably estimable. Amounts so accrued are not discounted.
