Abstract:
A multi-layered pressure packaging comprises a first container including a lockable neck portion followed by a body part and a bottom part, obtained from a non-foamed thermoplastic material by stretch blow molding, and a first layer at least enclosing the body part and/or bottom part of the first container. The first layer comprises foamed material, and the foamed material layer is foamed in place with an outer enclosure applied over and around the first container defining a free space in between, and foamable material introduced and foamed between the first container and the outer enclosure in the free space, obtaining the foamed material layer. A second layer is applied on the outer surface of the foamed layer for keeping the foamed layer and the first container together. Methods are provided for manufacturing a multi-layered pressure packaging according to an embodiment.
