Abstract

The invention relates to a process for the production of shaped bodies, in particular packaging shaped bodies, from biologically decomposable material using a viscous mass containing biologically decomposable fiber material, water and starch, which is baked with the formation of a composite of fiber material and starch in a baking mould, and a shaped body produced according to this process. The use of native and pre-gelatinated or modified starch in connection with a fiber material feed stock from fibers or fiber bundles of differing lengths is especially advantageous.
