Straws are not only used for takeout, office, banquets, family hospitality, etc., but also for drinking coffee, wine, soymilk and other drinks. Plastic straws are cost-effective and convenient to use, making them the first choice of many people. However, plastic straws are difficult to degrade in soil, causing great harm to Marine organisms. Dongguan Hengsheng Straw manufacturer uses environmentally friendly PLA degradable straw, replacing the common plastic straw. So what are the advantages of PLA biodegradable straws over plastic straws?

PLA(polylactic acid) is a new kind of biodegradable material. The production method is: using renewable plant resources (cassava, corn and other crops) to extract starch, starch raw materials through saccharification to get glucose, and then the glucose is metabolized and fermented into high purity lactic acid, and then through the synthesis method to get high molecular weight polymeric lactic acid, and then processed into a variety of good performance, biodegradable straw.

PLA straw has good biodegradable performance, degradation into CO2 and H2O, no pollution to the environment, can meet the needs of industrial compost. The straw after high temperature extrusion has good thermal stability, good solvent resistance, its product gloss, transparency, feel properties can replace petroleum-based products, the physical and chemical indicators of the product can meet the requirements of food safety laws and regulations in different places. So its application is very wide, basically can adapt to the needs of most drinks in the current market.

PLA straw has good moisture-proof and airtight and stable performance at room temperature, but will decompose automatically under the action of oxygen rich and microorganisms at temperatures higher than 45℃. Special attention should be paid to the temperature during the transportation and storage of the product. Long-term high temperature will cause deformation of PLA straw.

Due to the limitation of raw material properties, PLA straw cannot be used for hot drinks in the process of use, and is more suitable for cold drinks. It is believed that in the future, continuous technological improvement and innovation will gradually develop straw products that are both high temperature resistant and environmental protection.

RBT Straw manufacturer through continuous development and production, PLA degradable straw is constantly improving, because it has certain degradation effect in the process of use, so it can replace the current plastic straw for use, and meet the current environmental protection requirements.
