Analyze the pros and cons of PLA straws

    What does PLA mean? The full name is Poly-Lactic Acid, a new type of environmentally friendly polymer material obtained by ring-opening polymerization of lactic acid made from bio-based corn starch as a monomer, and can be completely degraded into environmentally friendly end products, such as CO2 and H2O.

    Because of its high mechanical strength, easy processing, high melting point, biodegradability and good biocompatibility, it has been widely used in agriculture, food packaging, medical and health fields. In recent years, the most attention has been paid to PLA degradable straws.

    PLA straws are used to replace plastic straws. Although it has the advantages of being degradable and environmentally friendly, it is considered to be superior to other alternative-paper straws in terms of user experience, but it also has some disadvantages.

    PLA material has a low thermal deformation temperature, which will become soft when it exceeds 50°C. It will soften and deform when encountering high-temperature liquids, while plastic straws will not.

    PLA straws are more suitable for warm and cold drinks, with a temperature resistance of -10°C to 50°C. Milk tea or refreshing coffee for warming hands in winter should be much higher than 50°C. PLA straws are not suitable for such products. Perhaps paper straws are a good choice.

    Although plastic straws have the advantages of low price and high heat distortion temperature, in order to protect the environment, we still try to minimize the use of plastic straws. Compostable PLA straws produced by Zhejiang Pando EP Technology Co., Ltd., paper straws or your own glass straws are all good choices.
