PLA's extrusion process is not easy

PLA's extrusion process is not easy, is only suitable in some advanced PET extrusion molding machine for processing, and the thickness of the extruded sheet only in the range of 0.2-1.0mm. Ethyl lactate moisture content and are particularly sensitive to the processing temperature, extrusion processing, generally requires its moisture content is less than 50PPM, this equipment drying system and temperature control system also proposed new requirements. Processing, if no suitable crystallization apparatus, magnessium lactate of scrap is also a major problem, which is on the market a large number of scrap in circulation causes PLA.
