1. Polylactic acid (PLA) is a new type of biodegradable material made from starch raw materials proposed by renewable plant resources such as corn. The starch raw material is saccharified to obtain glucose, and then fermented by glucose and certain strains to produce high-purity lactic acid, and then synthesize polylactic acid with a certain molecular weight by chemical synthesis. It has good biodegradability and can be completely degraded by microorganisms in nature after use, eventually producing carbon dioxide and water without polluting the environment, which is very beneficial to protecting the environment and is recognized as an environmentally friendly material.
Ordinary plastics are still treated by incineration and cremation, causing a large amount of greenhouse gases to be discharged into the air, while polylactic acid plastics are buried in the soil for degradation, and the carbon dioxide produced directly enters the soil organic matter or is absorbed by plants, and will not be discharged into the air. Does not cause greenhouse effect.
2. Good mechanical and physical properties. Polylactic acid is suitable for various processing methods such as blow molding and thermoplastic, and is easy to process and widely used. It can be used to process various plastic products from industry to civilian use, packaged food, fast food lunch boxes, non-woven fabrics, industrial and civilian fabrics. Then it can be processed into agricultural fabrics, health care fabrics, rags, hygiene products, outdoor anti-ultraviolet fabrics, tent fabrics, floor mats, etc. The market prospect is very promising.
3. Good compatibility and degradability. Polylactic acid is also widely used in the medical field, such as the production of disposable infusion sets, surgical sutures, etc., and low-molecular polylactic acid as drug sustained-release packaging agents.
4. In addition to the basic characteristics of biodegradable plastics, polylactic acid (PLA) also has its own unique characteristics. Traditional biodegradable plastics are not as strong, transparent and resistant to climate change as ordinary plastics.
5. The basic physical properties of polylactic acid (PLA) and petrochemical synthetic plastics are similar, that is to say, it can be widely used to manufacture various application products. Polylactic acid also has good gloss and transparency, comparable to films made of polystyrene, which other biodegradable products cannot provide.
6. Polylactic acid (PLA) has the best tensile strength and elongation. PLA can also be produced by various common processing methods, such as: melt extrusion molding, injection molding, blown film molding, foam molding and vacuum molding, It has similar forming conditions to widely used polymers, and it also has the same printing properties as conventional films. In this way, polylactic acid can be made into various application products according to the needs of different industries.
7. Polylactic acid (PLA) film has good air permeability, oxygen permeability and carbon dioxide permeability, and it also has the characteristic of isolating odor. Viruses and molds are easy to attach to the surface of biodegradable plastics, so there are doubts about safety and hygiene. However, polylactic acid is the only biodegradable plastic with excellent antibacterial and anti-mildew properties.
8. When incinerating polylactic acid (PLA), its combustion calorific value is the same as that of incinerating paper, which is half of that of incinerating traditional plastics (such as polyethylene), and incinerating PLA will never release toxic gases such as nitrogen and sulfide . The human body also contains lactic acid in monomeric form, which indicates the safety of this decomposing product.
