Document Type and Number:
WIPO Patent Application WO/2018/230565
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a packaging bag provided with a weakening line that can be appropriately utilized. This packaging bag is rectangular in shape and has an accommodating part formed by superposing films and sealing at least three end edges. A weakening line along which the strength of the films is reduced is formed on the accommodating part so as to be set apart from seal parts in plan view. The packaging bag further comprises a notch formed on at least one end edge from among three end edges, the notch serving as a mechanism for breaking the film when the accommodating part is opened. The weakening line is formed, in a direction orthogonal to the end edge in which the notch is formed, along a straight line extending from the notch to the end edge opposing the end edge in which the notch is formed.
