Title:
MULTILAYERED STRUCTURE, LAMINATE AND METHODS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2011/125739
Kind Code:
A1
Abstract:
Provided are: a multilayered structure which has very good gas barrier properties, excellent flex resistance, excellent pinhole resistance, high stretchability, excellent heat moldability and excellent interlayer adhesiveness and also has such good durability as to sustain the characteristics such as good gas barrier properties even in the case of being used in a deformed state (e.g., bended or stretched); a laminate using the multilayered structure; and a method for producing the multilayered structure and a method for producing the laminate. The aforesaid multilayered structure comprises four or more adjacently layered resin layers, the layers being formed of a resin composition containing an ethylene-vinyl alcohol copolymer. It is preferred that the average single layer thickness of the resin layers is 0.01 to 10 µm inclusive. It is preferred that the average thickness of the multilayered structure is 0.1 to 1,000 µm inclusive. It is preferred that the ethylene-vinyl alcohol copolymer has an ethylene unit content of 3 to 70 mol% inclusive and a degree of saponification of 80 mol% or greater.
