<p>PROBLEM TO BE SOLVED: To provide an easily unsealable packaging bag sealed at the peripheral edges in which linearity and ease in cutting are improved and the bag can be reliably cut off when the bag is cut and torn from a notch of the side edge thereof to unseal it. SOLUTION: In the easily unsealable packaging bag, sealant film surfaces of two composite films are joined together and sealed on the peripheries thereof to form edge sealed parts 12, 14, 16, and the lower part of the upper edge sealed part 16 is cut to unseal the bag. An upper and lower half-cut grooves 15a, 15b, which are to be cut and torn, are provided on the surface of the bag, and a notch 18 is formed at an end of the sealed part 12 between the grooves 15a, 15b and one or a plurality of half-cut grooves 17 protrude from the forward end 18a of the notch 18 slightly inwardly of a side edge seal part 12.</p> |
