Bioabbaubare thermoplastisch verformbare Materialien für Lebensmittelverpackungen

摘要

According to the invention the materials consist of blends of starch esters and aliphatic straight-chained or branched polycarbonates in a ratio of 5:95 to 95:5. Instead of usual softeners for starch esters so-called secondary softeners, which act at the same time as compatibility mediators, are used. The manufactured blends are distinguished by good migration values.
