Abstract:

A synthetic resin bag body with easy open function that facilitates peel from its opening portion side, preventing peel from the interior of the bag body. The synthetic resin bag body is one comprising two trunk part films (1a,1b) disposed on the front and back sides, wherein two easy peel tapes (4a,4b) composed of easy peel layers and a thermal adhesion layer wherein the easy peel layers opposite to each other are weakly bonded together (6) are strongly bonded together (5a,5b) across the lateral whole width of the inside of the individual trunk part films (1a,1b) at opening portion (2) of the bag body while creating C1-C2 long-and-short bonding width difference in the direction of width of the easy peel tapes (4a,4b) perpendicular to the direction of bag lateral width in the thermal adhesion layer. Accordingly, there can be attained facilitation of peel from the side of opening portion (2) of the bag body and prevention of peel from the interior of the bag body.
