摘要

"The structure of multiple layers for the packaging, container and methods for manufacturing a structure of multiple layers and a container molded by blow extrusion".The invention relates to a structure of multiple layers (10; 20; 30; 40) for packaging having a stiffness of at least 100 Mn.Comprising at least an intermediate layer of a polymer foam (11; 21; 31; 41) and on each side of said expanded polymer, a gas barrier layer (12,13: 22,23; 34,35; 42.43), and a method for the manufacture of that structure of multiple layers. The invention also relates to packaging containers (80; 90) made of the structure of multiple layers.Especially it relates to containers molded by extrusion / blow (90), and a method for the production of such containers molded by extrusion / blow.
