MULTILAYER STRUCTURE FOR PACKAGING AND PACKAGING CONTAINERS MANUFACTURED THEREFROM, AS WELL AS METHOD FOR MANUFACTURING OF THE MULTILAYER STRUCTURE

摘要

The invention relates to a multilayer structure (10; 20; 30; 40) for packaging having a rigidity of at least 100 mN, at least comprising an intermediate layer of an expanded polymer (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 manufacturing of said multilayer structure. The invention also relates to packaging containers (80; 90) manufactured from the multilayer structure. In particular it relates to extrusion/blow moulded containers (90), and a method for producing such extrusion/blow moulded containers.
