Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Our Condensed Consolidated Financial Statements include all of the accounts of the Company and our subsidiaries. We have eliminated all significant intercompany transactions and balances in consolidation. In management’s opinion, all adjustments, consisting only of normal recurring accruals, necessary for a fair statement of our Condensed Consolidated Balance Sheet as of June 30, 2021 and our Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2021 and 2020 have been made. The results set forth in our Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2021 and in our Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year. The Condensed Consolidated Balance Sheet as of December 31, 2020 was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. Some prior period amounts, including the geographic regions described below, have been reclassified to conform to the current year presentation. These reclassifications, individually and in the aggregate, did not have a material impact on our condensed consolidated financial condition, results of operations or cash flows. All amounts are in millions, except per share amounts, and approximate due to rounding. All amounts are presented in U.S. dollar, unless otherwise specified. Our Condensed Consolidated Financial Statements were prepared in accordance with the interim reporting requirements of the SEC. As permitted under those rules, annual footnotes or other financial information that are normally required by U.S. GAAP have been condensed or omitted. The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in our Condensed Consolidated Financial Statements and accompanying notes. Actual results could differ from these estimates. We are responsible for the unaudited Condensed Consolidated Financial Statements and notes included in this report. As these are condensed financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (“2020 Form 10-K”) and with the information contained in our other publicly-available filings with the SEC. When we cross reference to a “Note,” we are referring to our “Notes to Condensed Consolidated Financial Statements,” unless the context indicates otherwise. There were no significant changes to our significant accounting policies disclosed in “Note 2 – Summary of Significant Accounting Policies and Recently Issued Accounting Standards” of our Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the SEC on February 25, 2021. As of January 1, 2021, we consolidated the reporting of the North America and South America geographic regions, which are now collectively presented as Americas within Note 3, “Revenue Recognition, Contracts with Customers” and Note 5, “Segments.” No changes were made to EMEA or APAC. This change has no impact on our prior period consolidated results and is only the aggregation of the previously bifurcated continents. Where applicable, prior periods have been retrospectively adjusted to reflect the new geographic regions.
Recently Adopted and Issued Accounting Standards	Recently Adopted Accounting Standards In January 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”). ASU 2021-01 provides temporary optional expedients and exceptions to certain guidance in U.S. GAAP to ease the financial reporting burdens related to the expected market transition from London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). The guidance is effective upon issuance, on January 7, 2021, and can be applied through December 31, 2022. This update did not have a material impact on the Company's Condensed Consolidated Financial Statements. In January 2020, the FASB issued ASU 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323) and Derivatives and Hedging (Topic 815) - Clarifying the Interactions Between Topic 321, Topic 323, and Topic 815 (“ASU 2020-01”). ASU 2020-01 makes improvements related to accounting for certain equity securities when the equity method of accounting is applied or discontinued and provides scope considerations related to forward contracts and purchased options on certain securities. The Company adopted ASU 2020-01 on January 1, 2021. The adoption did not have a material impact on the Company's Condensed Consolidated Financial Statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 eliminates certain exceptions to the guidance in Topic 740 related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes, enacted change in tax laws or rates and clarifies the accounting transactions that result in a step-up in the tax basis of goodwill. The Company adopted ASU 2019-12 on January 1, 2021. The adoption did not have a material impact on the Company's Condensed Consolidated Financial Statements.
Revenue Recognition, Contracts with Customers	Description of Revenue Generating Activities We employ sales, marketing and customer service personnel throughout the world who sell and market our systems, products and services to and/or through a large number of distributors, fabricators, converters, eCommerce and mail order fulfillment firms, and contract packaging firms as well as directly to end-users such as food processors, food service businesses, supermarket retailers, pharmaceutical companies, healthcare facilities, medical device manufacturers, and other manufacturers. As discussed in Note 5, “Segments,” our reporting segments are Food and Protective. Our Food applications are largely sold directly to end customers, while our Protective products are sold through business supply distributors and directly to the end customer. Food: Food solutions are sold to perishable food processors in fresh red meat, smoked and processed meats, poultry, seafood, plant-based and dairy (solid and liquids) markets worldwide. Food offers integrated packaging materials and automated equipment solutions to increase food safety, extend shelf life, automate processes and optimize total cost. Its materials, automated equipment and service enables customers to reduce costs and enhance their brands in the marketplace. Food solutions are utilized by food service businesses (such as restaurants and entertainment venues) (“food service”) and food retailers (such as grocery stores and supermarkets) (“food retail”), among others. Solutions serving the food service market include products such as barrier bags and pouches, and are primarily marketed under the CRYOVAC® trademark and other highly recognized trade names including CRYOVAC® brand Barrier Bags, CRYOVAC® brand Form-Fill-Seal Films, and CRYOVAC® brand Auto Pouch System. Solutions serving the food retail market include products such as barrier bags, film, and trays, and are primarily marketed under the CRYOVAC® trademark and other highly recognized trade names including CRYOVAC® brand Grip & TearTM, CRYOVAC® brand Darfresh®, OptiDure™, Simple Steps®, and CRYOVAC® brand Barrier Bags. Protective: Protective packaging solutions are utilized across many global markets to protect goods during transit and are especially valuable to eCommerce, consumer goods, pharmaceutical and medical devices and industrial manufacturing. Protective solutions are designed to increase our customers' packaging velocity, minimize packaging waste, reduce labor dependencies and address dimensional weight challenges. Protective solutions are sold through a strategic network of distributors as well as directly to our customers, including, but not limited to, fabricators, original equipment manufacturers, contract manufacturers, logistics partners and eCommerce/fulfillment operations. Protective solutions are marketed under SEALED AIR® brand, BUBBLE WRAP® brand, AUTOBAG® brand and other highly recognized trade names and product families including BUBBLE WRAP® brand inflatable packaging, SEALED AIR® brand performance shrink films, AUTOBAG® brand bagging systems, Instapak® polyurethane foam packaging solutions and Korrvu® suspension and retention packaging. In addition, we provide temperature assurance packaging solutions under the KevothermalTM and TempGuardTM brands. Revenue Recognition Revenue from contracts with customers is recognized upon transfer of control to the customer. Revenue for materials and equipment sales is recognized based on shipping terms, which is the point in time the customer obtains control of the promised goods. Maintenance revenue is recognized straight-line on the basis that the level of effort is consistent over the term of the contract. The transaction price is allocated to each standalone performance obligation in the contract based on observable selling prices or one of the following three methods: an adjusted market assessment approach, expected cost plus a margin approach, or residual approach. We include in the transaction price some or all of an amount of variable consideration estimated to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Charges for rebates and other allowances are recognized as a deduction from revenue on an accrual basis in the period in which the associated revenue is recorded. Revenue recognized for the three and six months ended June 30, 2021 from performance obligations satisfied in previous reporting periods was $1.0 million and $0.8 million, respectively, and $1.2 million and $2.2 million for the three and six months ended June 30, 2020, respectively. The Company does not adjust consideration in contracts with customers for the effects of a significant financing component if the Company expects that the period between transfer of a good or service and payment for that good or service will be one year or less. This is expected to be the case for the majority of the Company's contracts. Lease components within contracts with customers are recognized in accordance with ASC 842.

Revenue Recognition, Contracts with Customers

Description of Revenue Generating Activities

We employ sales, marketing and customer service personnel throughout the world who sell and market our systems, products and services to and/or through a large number of distributors, fabricators, converters, eCommerce and mail order fulfillment firms, and contract packaging firms as well as directly to end-users such as food processors, food service businesses, supermarket retailers, pharmaceutical companies, healthcare facilities, medical device manufacturers, and other manufacturers.

As discussed in Note 5, “Segments,” our reporting segments are Food and Protective. Our Food applications are largely sold directly to end customers, while our Protective products are sold through business supply distributors and directly to the end customer.

Food:

Food solutions are sold to perishable food processors in fresh red meat, smoked and processed meats, poultry, seafood, plant-based and dairy (solid and liquids) markets worldwide. Food offers integrated packaging materials and automated equipment solutions to increase food safety, extend shelf life, automate processes and optimize total cost. Its materials, automated equipment and service enables customers to reduce costs and enhance their brands in the marketplace.

Food solutions are utilized by food service businesses (such as restaurants and entertainment venues) (“food service”) and food retailers (such as grocery stores and supermarkets) (“food retail”), among others. Solutions serving the food service market include products such as barrier bags and pouches, and are primarily marketed under the CRYOVAC® trademark and other highly recognized trade names including CRYOVAC® brand Barrier Bags, CRYOVAC® brand Form-Fill-Seal Films, and CRYOVAC® brand Auto Pouch System.

Protective:

Protective packaging solutions are utilized across many global markets to protect goods during transit and are especially valuable to eCommerce, consumer goods, pharmaceutical and medical devices and industrial manufacturing. Protective solutions are designed to increase our customers' packaging velocity, minimize packaging waste, reduce labor dependencies and address dimensional weight challenges.

Protective solutions are sold through a strategic network of distributors as well as directly to our customers, including, but not limited to, fabricators, original equipment manufacturers, contract manufacturers, logistics partners and eCommerce/fulfillment operations.

Revenue Recognition

Revenue from contracts with customers is recognized upon transfer of control to the customer. Revenue for materials and equipment sales is recognized based on shipping terms, which is the point in time the customer obtains control of the promised goods. Maintenance revenue is recognized straight-line on the basis that the level of effort is consistent over the term of the contract.

The transaction price is allocated to each standalone performance obligation in the contract based on observable selling prices or one of the following three methods: an adjusted market assessment approach, expected cost plus a margin approach, or residual approach. We include in the transaction price some or all of an amount of variable consideration estimated to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

Charges for rebates and other allowances are recognized as a deduction from revenue on an accrual basis in the period in which the associated revenue is recorded. Revenue recognized for the three and six months ended June 30, 2021 from performance obligations satisfied in previous reporting periods was $1.0 million and $0.8 million, respectively, and $1.2 million and $2.2 million for the three and six months ended June 30, 2020, respectively.

The Company does not adjust consideration in contracts with customers for the effects of a significant financing component if the Company expects that the period between transfer of a good or service and payment for that good or service will be one year or less. This is expected to be the case for the majority of the Company's contracts.

Lease components within contracts with customers are recognized in accordance with ASC 842.
