Abstract

Homogeneous mixtures are described and can be processed to give shaped biodegradable and physiologically nonhazardous articles, such as packagings for food or drink or pharmaceutical products, sausage casings and the like. The mixtures comprise dialdehyde starch with a degree of oxidation of greater than 30%, starch which does not exhibit any iodine-starch reaction, and/or modified starch, water and other plasticizers, and also, if desired, other biopolymers and additives.
