Claims

[Claims for Utility Model Registration] (1) An easy-to-open soft resin that is sealed with a vertical heat-seal back pasted between the upper and lower horizontal heat-seals, and has a cut on the side edge for opening. In the bag-making structure, the original film as the material is oriented, and the backing is heat-sealing the multilayer film to the side edge of the bag body through welding holes in at least one pair of opposing film layers. An easy-to-open soft resin bag structure characterized by being stacked and integrated. (2) The easy-to-open soft resin bag structure according to claim 1, wherein the horizontal heat seal is formed in a plurality of strips. (3) The easy-open soft resin bag structure according to claim 1, wherein the cut is formed in the horizontal seal portion. (4) The easy-open soft resin bag structure according to claim 1, wherein the cut is formed outside the horizontal seal portion. (5) The easy-to-open soft resin bag structure according to claim 1, wherein the spine is formed on the folded portion. (6) The easy-to-open soft resin bag structure according to claim 5, wherein the folded portion is formed in multiple layers.
