BREAD PACKAGING COEXTRUSION MULTILAYERED FILM, BREAD PACKAGING LAMINATED FILM AND BREAD PACKAGING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a bread packaging coextrusion multilayered film having oxygen gas barrier properties suitable for the medium period preservation of bread and easy to manufacture, a bread packaging laminated film and a bread packaging method using the bread packaging laminated film.;SOLUTION: The bread packaging coextrusion multilayered film is constituted by laminating a propylene polymer-containing resin layer (A), adhesive resin layers (X1) and (X2), a gas barrier resin layer (B) with a thickness of 1-8 m containing a polyamide resin and a polypropylene copolymer-containing resin layer (C) in the order of (A)/(X1)/(B)/(X2)/(C). The bread packaging laminated film is constituted by laminating a base material on the resin layer (A) of the multilayered film. In the bread packaging method, a bag formed by heat-sealing those films is filled with bread, a carbon dioxide gas and/or a nitrogen gas before heat-sealed to be hermetically closed.;COPYRIGHT: (C)2006,JPO&NCIPI
