Title:
MULTILAYERED PRODUCT
Document Type and Number:
Japanese Patent JP3260530
Kind Code:
B2
Abstract:
PURPOSE: To prevent the generation of a pinhole and to keep sufficient airtightness by forming the barrier plastic layer in a multilayered structure in the closest vicinity to a fiber base packaging material layer.
CONSTITUTION: In a multilayered product, especially, a multilayered product for producing container, a layer 1 molded from a fiber base packaging material is provided on one surface of an airtight multilayered plastic coating 3. The airtight multilayered plastic coating 3 is molded from a barrier plastic layer 4a of 1-4 g/m2 produced from a 32% ethylene/vinyl alcohol copolymer material, a binder layer 5 of 1-4 g/m2 produced from acid modified low density polyethylene and a surface layer 6 comprising a heat-sealable polyolefin material, for example, linear low density polyethylene having thickness sufficient for liquidtight heat-sealing all of which are superposed one upon another. The barrier plastic layer 4a in this multilayered structure is arranged in closest vicinity to the fiber base packaging material layer 1.
