Composición termoconformable esencialmente de base biológica y recipientes conformados a partir de la misma

摘要

An essentially biobased and optionally biodegradable, thermoformable composition containing a) as thermoformable resin at least one poly-L-lactide with less than 1 mol % of D-lactoyl units (PLLA) or at least one poly-L-lactide with 1-5 mol % of D-lactoyl units (PLA) and b) a nucleating combination of α) 1 to 10% Wt. of at least one poly-D-lactide with less than 1 mol % of L-lactoyl-units (PDLA) or of 0.5 to 5% Wt. of PLLA/PDLA or PLA/PDLA stereocomplex crystallites, &bgr;) 0.1 to 25% Wt. of an inorganic nucleating agent, and γ) 0.1 to 30% Wt. of at least an inorganic filler with lamellar structure, and thermoformed, essentially biobased and optionally biodegradable containers formed of the inventive compositions.
