Abstract
PURPOSE: To obtain multi-ply laminates having high gas barrier properties and improved processing characteristics, by laminating A) a resin layer containing a specific functional oligomer on B) a plasticizer-containing vinylidene chloride resin layer with C) a thin adhesive layer placed between A) and B).
CONSTITUTION: A) A layer of a carrier resin, e.g., vinyl chloride resin, etc, impregnated or blended with 5W70 wt.% of a functional oligomer having a number average molecular weight of 800W10,000 and/or fats and oils is laminated on at least one side of B) a vinylidene chloride resin layer containing 3W10 wt.% of a low molecular weight plasticizer having a number average molecular weight not more than 500 with C) a thin adhesive layer with a thickness of 0.1W5μ put between A and B. The low molecular weight plasticizer in the vinylidene chloride resin is transferred to the carrier resin layer to give the desired three- or more ply laminate. A polyester having a number average molecular weight of 1,000W8,000, obtained from a 6W10C aliphatic alkyl dicarboxylic acid and a 2W6C polyhydric alcohol may be cited as the above-mentioned oligomer or the fats and oils.
USE: Packaging materials for dried and retort foods, etc.
