Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesSilgan and its subsidiaries file U.S. Federal income tax returns, as well as income tax returns in various states and foreign jurisdictions. We expect the Internal Revenue Service, or IRS, will complete its review of the 2024 tax year with no change to our filed federal income tax return. We have been accepted into the Compliance Assurance Process program for the 2025 and 2026 tax years which provides for the review by the IRS of tax matters relating to our tax return prior to filing.
