FIELD: chemistry.
SUBSTANCE: invention relates to article containing single-layer or multilayer thermoplastic material, wherein the article is an optionally thermoformed sheet of plastic or comprises a thermoformed part which contains (i) from 88.00 to 99.85 % by weight of polylactic acid; (ii) from 0.15 to 1.00 % by weight of epoxidised vegetable oil; (iii) from 0 to 30.00 % by weight of additional additives selected from a group consisting of impact viscosity modifiers, plasticisers, cross-linkers, foaming agents, fillers, dyes, stabilizers, lubricants and mixtures thereof, wherein weight percentages are calculated relative to the total weight of the single-layer or multilayer thermoplastic material and, in total, they are 100 %.
EFFECT: presence of epoxidised vegetable oil in thermoplastic article in specified amount provides good breaking ability, good impact viscosity and transparency.
