CLOSURE EDGE PROTECTION VIA POLYMER COATED METAL

摘要

Metal closure components and methods for making the same are provided. The closures may be formed from a metal sheet (156) having a pre-formed polymer film (158) adhered on at least one face. A circular blank may be cut from the sheet, such that the blank may have a circular "raw" cut edge (160) unprotected by the polymer film. The metal blank may then be formed such that the cut edged may be embedded (172) into the film.
