A method of manufacturing biodegradable packaging material and apparatus therefor

摘要

An apparatus and a method for making a biodegradable material are disclosed. The apparatus comprises an extruder for forming a foamed starch rod and a heated die for modifying the rod. The rod is fed through the heated die by feeding rollers. A bonding agent application station is located downstream of the heated die and upstream of a packing unit. The method comprises forming a foamed starch rod by extrusion and passing the rod through a heated die. The rods may be formed into sheets or blocks by cutting, the application of bonding agent and adhering the cut rods together.
