PLA is expected to replace transparent materials

generally speaking, PLA is the most suitable alternative to transparent materials, especially those with high density and high price. The preferred ones should be pet (density 1.4g/cm3, analog sensor in pre price operation, digital sensor in post price operation, lattice hovering at $0.32/kg), soft PVC (density 1.3 g/cm3, price hovering at $0.3/kg) and cellulosic plastic (such as sirosphin). Compared with PP (density 0.9 g/cm3, price $0.16/kg) and hips (density 1.05 g/cm3, price $0.30/kg), PLA has no advantage. Under the current situation, it is impossible for PLA to replace PP and hips, unless the environmental problems are very prominent

c no strong magnetic field interference by providing personalized customized appearance color design, Dow believes that from the perspective of transparency (low haze) and gloss, PLA is in the same queue with pet, PVC, OPS and sirosphine. The haze of film grade plas is 2.1%, which can compete with some resins in the field of high transparent packaging

pla has high stiffness, which can be reflected in the tensile modulus of PLA film up to 33744kg/cm2 and extruded sheet 35150 kg/cm2. This figure means that the thickness of hips sheet can be reduced by 15~20% and 25% compared with that of sirol porphyrin film. Manufacturers of twisted packaging of candy, multilayer FFS structure and shrink film have high interest in PLA film. Hoechst trespaphan GmbH, Teich Flexibles and other companies are conducting research and development
