Title:
MULTILAYER STRUCTURE FOR PACKAGING
Document Type and Number:
WIPO Patent Application WO2004101273
Kind Code:
A9
Abstract:
A multilayer structure which comprises at least an inner layer, an outer layer, and an interlayer. Important features thereof reside in that the interlayer has a sea-island structure which comprises a resin (A) constituting the sea part and a functional resin (B) constituting the island part and which gives an interlayer section in which the area of the sea part accounts for 80% or smaller, and that the inner and outer layers comprise a resin having adhesion to the resin (A). Thus, adhesion between the layers can be improved without disposing a special adhesive layer between the interlayer, which has functions such as gas-barrier properties, and each of the inner and outer layers. In addition, transparency also can be improved.
