STAERKELSEBASERAD POLYMERBLANDNING SPECIELLT FOER FRAMSTAELLNING AV FILM OCH DYLIKT SAMT FOERFARANDE FOER DESS FRAMSTAELLNING.

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.
