<p><P>PROBLEM TO BE SOLVED: To provide a packaging bag with reclosing performance in which an opening can be formed by opening by hands after contents are filled and sealed, the contents as needed can be taken out from the opening, and then the opening can be simply resealed. <P>SOLUTION: The packaging bag has fringe heat-adhesion portions which are formed so that surfaces of heat-adherent resin layers of a laminated body 10 in which base materials 11 and the heat-adherent resin layers are laminated via hot melt adhesive layers face each other and fringes thereof are heat-adhered. A half-cut 4 of an open shape is formed from the base materials 11 sides, and an inner half-cut 5 of an open shape which is smaller than the half-cut 4 is provided along the half-cut 4 from the heat-adherent resin layers sides. Outer fringes of the fringe heat-adhesion portions and positions on which the half-cut 4 and the half-cut 5 are provided are in an unformed portion in which the hot melt adhesive layers are removed. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
