POUCH IMPROVED IN IMPACT RESISTANCE AND SEALING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pouch prevented from the cutting of a film generated at the boundary of the sealed part on the inner side of the pouch and the film by a drop impact, and a sealing method. SOLUTION: In the pouch formed by heat-sealing a plastic film having a heat-sealable plastic layer arranged on at least the inner surface side thereof and improved in impact resistance, the peel strength of the part on the inner side of the pouch of the heat sealed part is made less than that of the part on the outer side of the pouch.
