Biaxially stretched film is by far the most successful PLA film after biaxially stretched and heat set temperature resistant Sodium lactate can be increased to 90 ℃, just to make this defect is not high temperature of PLA. Through the two-way stretch orientation and the adjustment setting process can also control BOPLA membrane sealing temperature at 70 ~ 160 ℃. This advantage is not available in ordinary BOPET. In addition, BOPLA film transmittance of 94%, low haze, surface gloss is also very good, such membranes can be used for flower packaging,lactic acid powder, transparent window film, candy wrappers and so on.
PLA nonwoven fabric has been used is the spunbond nonwovens, plastic limit because of China's implementation of the non-woven shopping bags used for the production of the more popular. The blown film, lamination these two areas are some of the features because of defects PLA itself, applications still further exploration, some successful application cases is to use the modified PLA.
