Advantages of fully degradable PLA polylactic acid

1. Polylactic acid (PLA) is a new kind of biosoluble raw material. The raw material of tapioca starch obtained from renewable green plant resources (such as corn) is made into lactic acid bacteria through the whole alcoholization process, and then converted to polylactic acid according to the polymer generation. Polylactic acid has excellent biological solubility. After one year, the waste can be completely dissolved by microorganisms in the soil layer and converted into carbon dioxide and water, which does not cause environmental pollution to the natural environment. True and true is to ensure that "from course, into course"! Global carbon consumption, according to news reports in 2030, the temperature will rise to 60 ℃, general plastic solution is still the incineration cremation, lead to a lot of air pollutants into the air, the polylactic acid is dissolved in the buried in the soil layer, caused by carbon dioxide directly into the soil fertility or by green plants absorb, is not easy to rank in the air, Is not likely to contribute to global warming.

2. Excellent physical and technological performance. Polylactic acid is suitable for injection molding, injection molding and other various processing methods, convenient processing, the use of very common. It can be used to process a variety of food packaging materials from industrial production to civilian use, packaged food, Chinese fast food bento box, non-protective cloth, industrial production and civilian cloth. Thus processed into agricultural machinery textiles, health care textiles, towels, daily necessities, outdoor shielding ultraviolet fabrics, tent cloth, carpet, these industry prospects are very attractive.

3. Excellent compatibility and biodegradation. PLA is also widely used in the pharmaceutical industry. How to produce disposable infusion products, disassembly free surgical sutures, etc. Low-fractional structure polylactic acid as drug retarding packaging agent.

4, poly lactic acid (PLA) and petrochemical generated plastic basically have similar physical properties, in other words, it can be widely used in the production of a variety of applications of goods. Polylactic acid also has excellent gloss and clarity, and the plastic film made from polyethylene is very, very good, other biodegradable products can not give.

5. Polylactic acid (PLA) has the best compressive strength and elongation. PLA can also be produced by a variety of general processing methods, such as: Melt extrusion molding, injection molding, blowing film molding, polyurethane foam molding and vacuum pump molding, and the current stage of the common application of high polymer has similar molding standards, in addition to it also has the same packaging and printing characteristics as the traditional plastic film. In this way, polylactic acid can be made into a variety of application commodities according to the requirements of different industries.

6. Poly (lactic acid) plastic film has excellent air permeability, oxygen permeability and dioxygen and carbon permeability, but also has the characteristics of taste protection. Virus infection and Aspergillus flavus are easy to cling to the surface of biodegradable plastics, so there are concerns about safety and environmental hygiene. However, it is little known that PLA is a biodegradable plastic with excellent antibacterial and mildew resistance properties.
