5. Polylactic acid (PLA)
has similar basic physical properties to Petrochemical synthetic plastics, that is, it can be widely used to manufacture products for various applications. Polylactic acid also has good gloss and transparency, which is equivalent to the film made of polystyrene, which can not be provided by other biodegradable products.
6. Polylactic acid (PLA)
has the best tensile strength and ductility. PLA can also be produced by various common processing methods, such as melting extrusion molding, injection molding, film blowing molding, foaming molding and vacuum molding. It has similar forming conditions with widely used polymers. In addition, it also has the same printing properties as traditional films. In this way, polylactic acid can be made into a variety of application products according to the needs of different industries.
7. Polylactic acid (PLA)
film has good air permeability, oxygen permeability and carbon dioxide permeability. It also has the characteristics of isolating odor. Viruses and molds are easy to adhere to the surface of biodegradable plastics, so there are doubts about safety and hygiene. However, polylactic acid is the only biodegradable plastics with excellent antibacterial and mildew resistance.
8. When polylactic acid (PLA)
is incinerated, its combustion calorific value is the same as that of incinerated paper, which is half of that of incinerated traditional plastics (such as polyethylene), and the incinerated polylactic acid will never release toxic gases such as nitrides and sulfides. The human body also contains lactic acid in monomer form, which indicates the safety of this decomposition product.
