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.
