You may have noticed that pla straws are replacing plastic one... yes, plastic straws are gradually being replaced by pla straws due to their strong pollution and poor degradability. Those who love to drink milk tea should have noticed by now that the plastic straws that used to be there seem to have disappeared. Now let’s explore the reasons.
What Is PLA?
Polylactic acid PLA (Polylactic acid) is a new type of bioplastics. As early as 1932, WaIIace Carothers, a scientist at DuPont in the United States, polymerized lactic acid in a vacuum to produce low-molecular-weight polymers. However, due to high production costs, until In 1987, Cargill, a large American agricultural product company, began to invest in the research and development of a new polylactic acid manufacturing process. At present, NatureWorks, a subsidiary of Cargill, is the world's first industrialized polylactic acid manufacturer with a production capacity of approximately 140,000 ton.
Because polylactic acid material has both biocompatibility and biodegradability, it occupies 42% of the market in all decomposable plastics. In addition to the biodegradable properties, the main advantages of polylactic acid include good mechanical properties and its material source. The main source of polylactic acid is corn and other plant starches. Compared with the physical properties of other conventional plastics, the mechanical properties of polylactic acid are basically similar.
The scientific and technological research project of using polylactic acid PLA biomaterials to produce degradable straws began in 2005. After several years of hard work, our company has achieved a series of large results. We have developed various products under the premise of ensuring that the product features remain unchanged. A series of straws of various colors and varieties. The physical properties of the straw products have been gradually improved. The appearance and function of the straw are very close to the straws made of traditional polypropylene materials. They have good gloss and transparency, and are safe, hygienic and safe. Antibacterial and other advantages.
In view of the fact that the material source of the polylactic acid straw is the starch of various plants, the source of the matrix material is very wide. In the environment where the price of crude oil is rising and the oil storage capacity is gradually depleted, it not only has a very significant environmental protection advantage, but also has a very obvious social Benefits, and is expected to gradually replace the traditional polypropylene drinking straws in the near future.
Since Biodegradable Materials are mainly based on natural macromolecules or polyester species, a polymer made from renewable natural resources, such as microorganisms, plants, and animals, is a kind of polymer produced by its materials. Straw products will not be decomposed in general atmospheric environment and storage warehouses. With sufficient humidity, temperature and appropriate microbial conditions, they can be decomposed into H20 and CO2 by microorganisms after about 45 days in a natural burial or composting environment.
Two Stages Of Decomposition Of Biodegradable Straws
After being decomposed by hydrolysis reaction, it is decomposed by microorganisms. Hydrolysis occurs first in the natural environment, and then microorganisms enter the tissues and decompose it into carbon dioxide and water. Under composting conditions (high temperature and high humidity), the hydrolysis reaction can be completed easily and the decomposition rate is faster. In an environment where the hydrolysis reaction is not prone to occur, the decomposition process is gradual, and the decomposition cycle will be extended accordingly.
Advantages Of Biodegradable Straws
- The material is natural, non-toxic, and highly breathable. Some PLA products are approved by the US FDA and can be directly contacted with food. (Even if the food contains acidic and alcoholic ingredients, it will not release any hazardous substances to the human body;
- Using any waste treatment method (such as burying, recycling, composting) will not cause any impact on the environment. After being discarded, it can be completely decomposed by microorganisms through the composting environment and burial treatment;
- It can replace traditional plastic straws based on petroleum, and has the same physical properties as traditional plastic straws, and the method of use is the same.
