STARCH CONTAINING MIXTURES OF POLYMERS ESPECIALLY FOR MANUFACTURING FILMS AND FILM-LIKE MATERIALS AND METHOD FOR PRODUCING SAID STARCH CONTAINING MIXTURES OF POLYMERS

摘要

The material, which is usable for the production of biodegradable articles in film, sheet or fiber form, can be produced by extrusion from a molten mass including a synthetic thermoplastic polymer and a destructured starch to which a boron containing compound, such as boric acid, metaboric acid, borax and derivatives thereof has been added. Articles made of this material have improved transparency, Young's modulus and tear strength.
