A pillow type bag, wherein a peeling start portion is formed along an outer edge of at least one edge thermal bonding portion, and a back surface on which a gastric thermal bonding portion that forms a packaging bag is formed corresponding to the peeling starting portion. Two cut lines are formed on the side laminated body or the front side laminated body at regular intervals over the entire length of the bag in the direction parallel to the joint-sealed heat-bonded portion, and a cut is formed at the edge of the cut line at the peeling start portion. With this structure, the laminate is torn in the longitudinal direction along the two cut lines from the two cuts formed in the laminate while peeling the edge heat-bonded portion from the peeling start portion. As a result, the width sandwiched between the two scoring lines allows for vertical movement. It is possible to form the openings of the length of the can and the contents removed from the opening.
Also, by tearing over the entire length in the vertical direction,
The laminate sandwiched between the two score lines can be completely cut off to form a large vertical opening in the center of the packaging bag, so the packaging bag with the opening can be placed on a table or the like. The contents can be easily dispensed and taken out from this opening when placed.

図ることが可能となる。As a method of forming the score line, when the score line is formed in the intermediate layer of the laminate, a pattern is printed on the film to be the base layer, and the film to be the printed base layer and the intermediate layer are formed. When laminating films by dry lamination or extrusion lamination, the flow of the intermediate layer film by using a cutting blade or the like at a predetermined position corresponding to the pattern printed on the base layer film of the intermediate layer film. It is performed by a method of providing a linear cut line continuous in the direction. When forming a score line on the outer surface of the base material layer at a depth within the range of the thickness of the base material layer, a diamond needle or the like for forming the score line from the reference surface after the laminate is prepared. Using a score line forming tool whose tip protrudes by a predetermined dimension, the outer surface of the base layer at a predetermined position corresponding to the pattern printed on the base layer is brought into contact with the outer surface of the base layer under a constant load and laminated. By running the body, it is possible to form linear cut lines that are continuous in the flow direction of the film serving as the base material layer. Therefore, the process of forming the score lines in the laminate can be simplified, and the cost of the easy-open packaging bag can be reduced.

容物を小出し取り出しするのが容易となる。EFFECT OF THE INVENTION A pillow type bag comprising a laminated body having a base material layer and a heat-adhesive resin layer, and formed by a palm-shaped heat-bonded portion and an edge heat-bonded portion, and at least the edge heat-bonded portion is removable. And a peeling start portion is formed along the outer edge of at least one of the edge heat-bonding portions, and a back side laminate having a gas-sealing heat-bonding portion that forms a packaging bag corresponding to the peeling start portion, or Two cut lines are formed on the surface side laminated body at regular intervals over the entire length of the bag in a direction parallel to the joint thermal bonding portion, and a cut is formed at the edge of the cut line at the peeling start portion. By doing so, the edge heat-bonded portion is peeled from the peeling start portion, and the laminated body is vertically cut along the two cut lines from the two cuts formed in the laminated body to an arbitrary length. It is possible to form an opening of any size by tearing. In addition, by tearing the entire length of the bag in the vertical direction, the laminated body in the area surrounded by the two score lines and the edge heat-bonded portion is cut off to form a vertical opening in the central portion of the packaging bag. Therefore, it is easy to take out and take out the contents from the opening with the packaging bag having the opening placed on the table or the like.

を図ることが可能となる。In the above-mentioned easy-open packaging bag, the cut line is formed on the base material layer of the laminate at a depth within the range of the thickness of the base material layer, or the laminate has an intermediate layer. With the configuration in which the cut line is formed so as to penetrate the intermediate layer, the laminate can be easily torn along the cut line, and the gas barrier property of the laminate constituting the packaging bag can be reduced. Absent. Further, since it is not necessary to use a laminate having a structure including a uniaxially stretched film, and the process of forming the score line can be simplified, the cost of the easy-open packaging bag can be reduced.
