Biodegradable packaging material and process for producing the same

摘要

The material is based on polysaccharides and is characterised in that it is formed using a basic composition which is treated, preferably with pressure and/or temperature, for shaping and has a water content not exceeding 30 % by mass, in particular not exceeding 15 % by mass, or is adjusted thereto, and whose matrix is formed using the total digested composition which has a puree-like consistency ("puree") and is obtained by the chemical-thermal and/or enzymatic-thermal, and optionally mechanical, digestion treatment, known per se, of at least one vegetable waste product and/or byproduct with a content of - in each case based on or indicated as dry matter - at least 25 % by mass, preferably at least 50 % by mass, of cell wall polysaccharides, in particular cellulose(s), hemicellulose(s), lignin(s), pentosan(s) and pectin(s), and a process for the production thereof.
