Packaging bag obtained by using the same and a gas barrier composite film

摘要

PROBLEM TO BE SOLVED: To provide a gas barrier composite film adapted to a packaging bag having high gas barrier properties itself, enabling the utilization of ink designed from widely ranging materials by preventing the transfer of eluates from the solvent or pigment remaining in a printing layer into the bag using a gas barrier layer and capable of providing a package excellent in aesthetic properties and food sanitation properties.;SOLUTION: The gas barrier composite film is constituted by laminating the gas barrier layer and a sealant layer on the printing surface of a film, to which printing is applied, in this order. The gas barrier layer contains at least one gas barrier resin selected from the group consisting of a polyvinyl alcohol polymer and an ethylene/vinyl alcohol copolymer, and an inorganic lamellar compound in a mass ratio of 30/70-95/5.;COPYRIGHT: (C)2005,JPO&NCIPI
