LAMINATE AND MANUFACTURE OF BAG USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a laminate of a heat seal layer with barrier films having pattern layers on which the adhesion of foreign matters is not generated at least on the heat seal layer in the manufacturing process of the laminate for packaging. SOLUTION: Reinforcing layers 5 with at least barrier layers 4 are laminated to form a laminate 10 with reinforcing layers 5 of softening temperature higher than that of a cylindrical film T of heat seal properties. The barrier layer 4 is constituted of one kind or two kinds or more of aluminum foils, a polyvinylidene chloride coated film, a vapor-deposited film, and a polyvinyl alcohol or ethylene and vinyl acetate copolymer saponified material film.
