Abstract

PURPOSE: To provide the title film having a good interlayer adhesion and heat resistance by biaxially stretching after gluing ethylene.vinyl acetate copolymer saponified substance layer on a monoaxially oriented film base using specific copolymer as adhesives.
CONSTITUTION: On the polypropylene film base layer oriented monoaxially lengthwise the unsaturated carboxylic acid modified propylene copolymer adhesive layer 3 having a lower melting point than the baes layer will be laminated 0W20mm wide inside of the base end and after thereon laminating the ethylene.vinyl acetate copolymer saponification layer 2 10W40mm wide inside of the adhesive layer end, both ends of solely the base layer will be held between tenter graspers 4a, 4b will be horizontally stretched in order to provide the purposed biaxially oriented film.
USE: Packing materials
