A hollow plastic body comprises a material composite consisting of a stamp-formed panel or sheet-like first layer of a first thermoplastic synthetic material, an optionally stamp-formed panel or sheet-like second layer of a second synthetic material, and an open-cell or mixed-cell foam layer of a third synthetic material disposed between the first and the second layer. The foam layer may be compressed at least in some sections in accordance with the stamped form of the first layer and/or the second layer. The foam layer may be in mechanical contact with the first or/and second layer substantially only in the compressed sections. Advantageous manufacturing methods for hollow plastic bodies are further disclosed.
