Polylactic acid (PLA) is a new type of polyester material produced by using organic acid lactic acid as raw material. It has advantages over existing plastic polyethylene, polypropylene, polystyrene and other materials. It is defined by industry as the most promising future in the new century. The new packaging materials(PLA Non Woven Fabric Wholesale), which are environmentally-friendly packaging materials, will be expected to replace polyethylene, polypropylene, polystyrene and other materials for plastic products in the future.

Polylactic acid performance

Polylactic acid has good biodegradability. After use, it can be completely degraded by microorganisms in nature. Various products made from it can be completely degraded by burying it in the soil for 6 to 12 months. The waste after use is buried in the soil or water, and can be formed into carbonic acid gas and water under the decomposition of microorganisms. In the sunlight, they will form the starting starch by photosynthesis. In this way, through a cycle process, the initial raw material starch of polylactic acid can be recovered, and the content of carbon dioxide in the air is reduced by photosynthesis.

Polylactic acid has good mechanical properties and physical properties. It is suitable for various processing methods such as blow molding and thermoplastic molding. It is easy to process and widely used. It can be used to process all kinds of plastic products, packaged foods, fast food lunch boxes, non-woven fabrics(Degradable Nonwovens Factory), industrial and civil fabrics from industrial to civilian. Into the mouth-to-mouth into agricultural fabrics(Environmentally Friendly Non-woven Manufacturer), health care fabrics, rags, hygiene products, outdoor UV fabrics, tent fabrics, floor mats, etc., the market prospects are very promising.

Polylactic acid has good compatibility and degradability, and is widely used in the medical field, such as disposable infusion sets, disposable surgical sutures, etc., low-polylactic acid as a drug sustained-release packaging agent.

Polylactic acid is also a low-energy product that is 30% to 50% lower than polymers produced from petroleum products. It is expected that before the depletion of non-renewable petroleum resources, the market price of petroleum and its derivatives will skyrocket, and renewable products will become a tight consumer goods on a global scale.
