Title: MULTILAYER BAG
Abstract:
[Problem] To provide a multilayer bag that can be easily disposed of without separating a torn piece, resulting from tearing, from the multilayer bag body. [Solution] A multilayer bag is formed of a multilayer film including an outer film and an inner film. A back seal section at which ends of the multilayer film are laid on each other and are welded together over a predetermined width is formed. Furthermore, lateral seal sections at which edges and the vicinity thereof on the sides perpendicular to the back seal section are welded over a predetermined width are formed, thereby forming a multilayer bag that is filled with contents and sealed. A tearing-start part that allows the bag to be opened in the direction substantially parallel to the lateral seal sections is provided near the back seal section. Furthermore, a tearing-stop part is provided near an end of the multilayer bag, at a position corresponding to the position where the tearing-start part is formed.
