Patent
CA 2717757
The invention relates to a hollow plastic body comprising a material composite consisting of a stamp-formed panel or sheet-like first layer (10) of a first thermoplastic synthetic material, an optionally stamp-formed panel or sheet-like second layer (20) of a second synthetic material, and an open-cell or mixed-cell foam layer (30) of a third synthetic material disposed between the first and the second layer (10, 20). In this case, the foam layer (30) is compressed at least in some sections in accordance with the stamped form of the first layer (10) and/or the second layer (20). In a preferred embodiment, the foam layer (30) is in mechanical contact with the first or/and second layer (10, 20) substantially only in the compressed sections (70). Furthermore, the invention relates to an advantageous manufacturing method for hollow plastic bodies.
