LAMINATED FILM FOR PACKAGING, AND PACKAGING BAG

摘要

PROBLEM TO BE SOLVED: To provide a laminated film for packaging which can be cut laterally from any spots without being subjected to a process for giving the film cutting properties and has gas barrier properties while retaining a double-film structure consisting of a base material film and a sealant film, and to provide a packaging bag using the laminated film. SOLUTION: The laminated film for packaging is formed by laminating the base material film at least having cutting properties sidewise and a heat-weldable film at least having cutting properties sidewise. The packaging bag is made by heat welding the above laminated film for packaging. The gas barrier properties can be given to the base material film by depositing an aluminum or a metal oxide on the base material film. COPYRIGHT: (C)2006,JPO&NCIPI
