摘要： Packaging film with a coefficient of static friction >5 comprising:

(i) a biodegradable polyester with a melt strength of 0.7-4 g and comprising units of at least one dicarboxylic acid and at least one diol, and
(ii) an anti-fogging agent selected from the esters of a polyfunctional alcohol, provided that the ester is not a stearate.

摘要： Multilayer biodegradable film particularly suitable for use in the manufacture of packaging, comprising at least one layer (A) comprising at least one aliphatic-aromatic biodegradable polyester blended with an aliphatic polyester having at least 70% in moles of succinic acid, and at least one layer (B) comprising a polymer composition comprising an aliphatic-aromatic polymer. The film has high mechanical properties, in particular a high elastic modulus, and appreciable optical transparency properties.

摘要： Biodegradable polymer composition for the production of molded items comprising:



i. 5-70% by weight of a polyester comprising units derived from an aromatic dicarboxylic acid, succinic acid and a C5-C24 saturated dicarboxylic acid; and units derived from a saturated aliphatic diol and an unsaturated aliphatic diol;
ii 0-40% by weight of a polyester comprising units derived from succinic acid and units derived from a saturated aliphatic diol and an unsaturated aliphatic diol;
iii. 23-43% by weight of a polyhydroxyalkanoate;
iv. 10-20% by weight of a filler;
v. 0-0.5% by weight of a cross-linking agent and/or chain extender.
