Patent ID: 7927532

Claim:
A biodegradable polymer composition for the preparation of items that may be in contact with food material, comprising as starting materials: an organic peroxide in an amount more than 0 and up to 5% by weight, wherein said organic peroxide is selected from the group consisting of diacetyl peroxide, cumyl-hydro-peroxide, dibenzoyl peroxide, dialkyl peroxide, 2,5-methyl-2,5-di(terbutylperoxy)-hexane and mixtures thereof; between 40 and 97% by weight of poly(lactic acid) polymer; between 0.5 and 35% by weight of a co-polyester polymer with adipic acid; and nanoparticles in an amount more than 0 and up to 6% by weight and having an average particle size ranging between about 20 and about 500 nanometers, the nanoparticles having a degree of purity of at least 99.9% and being selected from the group consisting of silica and magnesium silicate, each on the basis of the total weight of the biodegradable polymer composition.
