A biodegradable film, 1 - Pilot plant investigation for production of the biodegradable film

A starch-based low density polyethylene (LDPE) biodegradable film was devel oped by a cost effective commercialized technology. In this process starch was blended with LDPE using a suitable proprietary coupling system. LDPE, s tarch and the coupling system were intimately compounded and extruded as st rands, which were subsequently processed by a film blowing extruder to make a biodegradable film. The quality of that firm was satisfactory in terms o f appearance, mechanical strength and biodegradability.
