EASILY OPENABLE PACKAGING BAG

摘要

PROBLEM TO BE SOLVED: To provide an easily openable packaging bag in which the bag is opened by releasing an end edge stuck part from a release starting part and a laminated body of either one of the surface and the back surface constituting the packaging bag is torn along cutting lines to form an opening with an arbitrary size in the up and down direction of the packaging bag. SOLUTION: The easily openable packaging bag has a constitution wherein the bag consists of a laminated body provided with a base material layer and a heat bonding resin layer and is a pillow-type bag formed by a hand-clasping- type heat bonding part and an end edge heat bonding part, which is at least releasable, and the release starting part is formed along the outer end of at least one end edge heat bonding part. Two cutting lines are formed at a definite interval over the whole length in the parallel direction to the hand-clasping-type heat bonding part on either one of the surface or the back surface laminated bodies constituting the packaging bag corresponding to the release starting part, and notches are formed on the end edges of the cutting lines at the release starting parts.
