PURPOSE:To make film adaptable for food packing material, whether it is the boilable type requiring boil sterilization or other type not requiring the same. CONSTITUTION:The co-extrusion molded composite film for deep drawing packing comprises an outer polybutylene terephthalate resin layer, an inner sealable resin layer, an intermediate barrier resin layer constituted of a saponified layer consisting of polyamide resin or copolymer of polyamide resin and ethylene vinyl acetate and two polyolefin adhesive resin layers, each interposed between the intermediate layer and each of the outer layer and the inner layer. This film is excellent in label adhesion, gloss and pinhole resistance, etc., and is suitably useable for packing various kinds of food. |
