PLASTIC BOTTLE FOR BEER COMPATIBLE WITH ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide a beer bottle of extremely high oxygen barrier properties and carbon dioxide gas barrier properties for trapping oxygen passed through a resin layer by providing a structural material resin layer or a gas barrier resin layer on both surface layers and also providing an oxygen trapping resin layer using a PET bottle recycle flakes generally as a low-molecular material PET on an intermediate layer. SOLUTION: A multilayer plastic bottle having the 0.05-4 liter content and the 0.1-2 mm total thickness of a bottle body section and containing a beverage PET bottle recycle material as an intermediate layer is constituted of two or more kinds of resins composed of a barrier resin or a structural material resin as a surface material and formed of three or more layers, and when a beer is filled, sealed and stored in atmosphere at 4-25 deg.C for 180 days, the infiltration amount of oxygen into the bottle is 1 ppm or less to the beer weight.
