Straws are not only used for takeaways, offices, banquets, family receptions, etc., but also for drinking coffee, alcohol, soy milk and other beverages. Plastic straws are cost-effective and easy to use, making them the first choice of many people. However, plastic straws are very popular in the soil. It is difficult to degrade and causes great harm to marine life. Straw manufacturer adopts environmentally friendly PLA biodegradable straws instead of common plastic straws. So what are the advantages of PLA biodegradable straws compared to plastic straws?
PLA (polylactic acid) is a new type of biodegradable material. Its production method is: use renewable plant resources (cassava, corn and other crops) to extract starch, starch raw materials are saccharified to obtain glucose, and then the glucose is metabolized and fermented by bacteria to produce high-purity lactic acid, and then high-purity lactic acid is obtained through synthetic methods. The molecular weight polymerized lactic acid is then processed and formed into various biodegradable straws with good performance.
The PLA straw has good biodegradability, degrades to produce CO2 and H2O, does not pollute the environment, and can meet the needs of industrial composting. The straw extruded at high temperature has good thermal stability and good solvent resistance. Its product gloss, transparency, and hand feel performance can replace petroleum-based products. The physical and chemical indicators of the product can meet the food safety regulations of various places. Require. Therefore, it has a wide range of applications and can basically meet the needs of most beverages on the market.
PLA straw has good moisture resistance and airtightness. It is stable at room temperature, but it will automatically decompose when the temperature is higher than 45℃ or under the action of oxygen and microorganisms. Pay special attention to the temperature during the transportation and storage of the product. Long-term high temperature will cause deformation of the PLA straw.
Due to the limitation of the properties of the raw materials, the PLA straw cannot be used for hot drinks during use. It is more suitable for cold drinks. I believe that in the future, the continuous improvement and innovation of technology will gradually develop straw products that are resistant to high temperatures and environmentally friendly.
