Thermoplastic collagen compositions comprising polyesters

Abstract

Blend compositions including: i) collagen, ii) water, iii) particularly a plasticizer, and iv) a polyester having a melting point equal to or lower than 120° C. The weight ratio of the collagen and the polyester in the blend composition is from 2:1 to 1:20. The blend composition provides a sheet having a water solubility equal to or lower than 40% w/w; and a homogeneous film when submitted to a blown film extrusion. The blend composition and corresponding films can be used to make solid articles, particularly those for use in the food industry, in the pet food sector, in the agricultural sector, or in the pharmaceutical sector.
