Title:
MULTILAYER STRUCTURE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2011/068105
Kind Code:
A1
Abstract:
The disclosed multilayer structure provided with at least eight resin layers is characterized by: having, as resin layers, A layers comprising a resin composition containing a gas-barrier resin, and B layers comprising a resin composition containing a thermoplastic resin; containing a metal salt within at least one of the resin compositions of the adjacent A layers and B layers; the quantity of contained metal salt being at least 1 ppm and no more than 10,000 ppm in terms of the metallic element; and the interlayer adhesive force between the A layers and the B layers being at least 450 g/15 mm. It is preferable that the A layers and B layers are layered in alternation. Furthermore, it is preferable for the average thickness of one layer of the A layers and/or the B layers to be at least 0.01 μm and no more than 10 μm.
