PLA extrusion grade resin

PLA extrusion grade resins are the major market applications, mainly for large supermarket fresh produce packaging, packaging has become such an important European market chain one; Calcium lactate advocate for safety, energy conservation, environmental protection, electronics packaging on. In these applications, PLA high transparency, high gloss, high rigidity, etc. reflected most vividly, is already the dominant direction of the PLA application. In addition, extrusion grade resin in horticultural applications are starting to get attention in the green slope, dust storms have been applied in other areas of governance.
However, 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. Process of moisture content and are particularly sensitive to the processing temperature, buffered lactic acid, 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, the recovery of scrap is also a major problem, which is on the market a large number of scrap in circulation causes PLA.
