摘要： A multi-layer polymer film comprising at least one middle layer A, the polymeric constituents of which are soluble in aqueous solution, and in each case at least one substantially water-impermeable covering layer B, C arranged above and below the at least one middle layer A, wherein the layers A, B and C independently of each other in each case comprise at least one thermoplastic polymer and at least one of the covering layers B and C comprises at least one polyhydroxyalkanoate is presented and described. Processes for the production of the multi-layer polymer film according to the invention and its use for the production of molded parts, films or bags are furthermore presented and described.

摘要： The invention relates to a polymer compound which, based on the total weight of the polymer compound, comprises at least the following components: (a) 5 to 50 wgt.-% destructed starch and/or starch derivative, (b) 20 to 70 wgt.-% aliphatic-aromatic copolymer, (c) 10 to 50 wgt.-% polyhydroxyalkanoate and (d) 3 to 25 wgt.-% polyactic acid. Such polymer compounds are characterized by a high ratio of bio-based carbon and exhibit no significant embrittlement or worsening of the mechanical properties profile, despite the presence of increased volumes of polyhydroxyalkanoate, even after storage. The invention further relates to production methods for the polymer compound according to the invention, and use thereof in the production of films, molded parts or fibers.
