CO-EXTRUSION COMPOSITE FILM FOR DEEP DRAW PACKAGING AND DEEP DRAW PACKAGE

摘要

PROBLEM TO BE SOLVED: To provide a co-extrusion composite film for deep draw packaging suitable for packaging block ham or the like having large inner volume and reducing the curl of a flange (seal part) even if a package is boiled especially in secondary sterilization or the like, and a deep draw package. SOLUTION: The co-extrusion composite film for deep draw packaging has successively laminated layered constitution of 610 nylon/adhesive resin/polyamide resin/gas barrier resin/adhesive resin/sealable resin or 610 nylon/adhesive resin/ gas barrier resin/polyamide resin/adhesive resin/sealable resin.
