Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a packaging bag (1) with at least two chambers (3) for storing objects to be packaged, wherein: the stacking of the chambers (3) for storing objects to be packaged on each other is easy; there is no danger of bag rupture from the chambers (3) for storing the objects to be packaged or a partition seal (2) for partitioning the chambers (3) for storing the objects to be packaged; and the packaging bag (1) can be torn open easily without soiling hands or fingers. The present application is for a packaging bag (1) obtained by overlaying a laminate film having at least a base film layer and a sealant layer on itself so that said sealant layers face each other and fusion-bonding the peripheral edges to each other. The packaging bag (1) has at least two chambers (3) for storing objects to be packaged, the chambers being demarcated by a partition seal (2). In the center of the width direction of the partition seal (2), the partition seal has an easily bending section (4) that extends continuously or discontinuously in the longitudinal direction and is more flexible than the partition seal (2).
