PROBLEM TO BE SOLVED: To provide a co-extruded composite film for deep draw molding which can be suitably used for packaging a food which is boiled and sterilized or without requiring for a boiling sterilization. SOLUTION: The co-extruded composite film for the deep draw molding comprises an outermost layer made of a polybutylene terephthalate resin layer, an innermost layer made of a sealable resin layer, an intermediate layer made of a barrier resin layer made of a saponified ethylene vinyl acetate copolymer layer, and polyolefin adhesive resin layers arranged between the outermost layer and the intermediate layer and between the innermost layer and the intermediate layer. The composite film has excellent label adhesive properties, gloss and pinhole resistance and can be used suitably for packaging various type foods. COPYRIGHT: (C)2003,JPO
