Polylactic acid film has good air permeability

 Polylactic acid (PLA) film has good air permeability, oxygen permeability, and two-carbon dioxide permeability resistance, it also has a characteristic odor isolation. Viruses and fungi easily attached to the surface of biodegradable plastic, so it is safe and hygienic concerns, however,Ethyl lactate acid is the only excellent antibacterial and antifungal properties of biodegradable plastics.
When incineration. polylactic acid (PLA), the heat of combustion of the burning of the same paper, incineration buffered lactic acid plastic (such as polyethylene) in half, and incineration of the polylactic acid will not release nitrides, sulfides and other toxic gases. The body also contains lactic acid monomer present in the form, which means that products of this decomposition have security.
