ABSTRACT:
A pouch adapted to accommodate medicine or the like comprising first and second compound films forming front and back surfaces of a pouch. Each of these compound films is composed of a resin film having a predetermined tear strength and a resin film having a good heat adhesive property and the first mentioned resin film is provided with a linear slit on one side thereof having un-cut portions. These compound films are overlapped with each other with the resin films having the heat adhesive property being disposed inside so as to oppose each other and with the slits formed to the resin films of the compound films forming the front and back surfaces of the pouch being coincident with each other in positions. The compound films are then heat fused. When a pouch is formed by these compound films, the pouch has an orientation capable of being torn in a direction corresponding to an extending direction of said slit. The orientation of the pouch along which the pouch is liable to be torn is made in consideration of the orientations of the resin films forming the compound films.
