Abstract

The invention relates to a process for producing a shaped body made of biodegradable material in which a bakeable mass is produced by mixing from 7.8 to 8.5% by weight of cellulosic fibers, from 16.1 to 17.6% by weight of native starch, from 5.4 to 6.0% by weight of pregelatinized starch and from 68.0 to 70.6% by weight of water, in each case based on the bakeable mass, and the bakeable mass is then baked to form a shaped body. The invention also relates to shaped bodies obtainable by this process and to their use as packaging material.
