PLA is a new type of biodegradable material


    On January 1, 2021, the national ban on plastic straws came into effect. The major coffee and milk tea drinks shops seem to have replaced paper straws overnight. But what I didn't expect was that the paper straws were softened and broken when the liquid was encountered, or the paper scraps were left in the drink and were drunk into the belly. Netizens, represented by the control of milk tea, were ranting about it.

    Under the plastic restriction order, paper straws may not be the best solution. After all, the consumer experience is not good, and the manufacturing cost has also increased a lot. Therefore, some restaurants have chosen PLA (polylactic acid) biodegradable straws. Although the cost is slightly higher, the user experience is no different from traditional plastic straws, and it is also environmentally friendly.

    Today, the editor takes everyone to learn about PLA degradable plastics and how WACKER VINNEX® additives used in PLA plastics can improve the material characteristics and processing performance on the basis of maintaining the biodegradability of the material, so that it can be processed And use it is more environmentally friendly.

    PLA degradable straws VS paper straws

    PLA is a new type of biodegradable material, which is made from the starch raw materials proposed by renewable plant resources such as corn.

    From the processing point of view, PLA biodegradable plastic has good mechanical properties and high stiffness. It also has high visual transparency, which can be described as the coexistence of strength and beauty.

    From the perspective of processing methods, PLA degradable plastics can be degraded in only 90 days under industrial composting conditions. The environmental performance is remarkable.

    PLA biodegradable plastic straws compared with paper straws:

    Use experience: PLA straws are too strong, which are more stable than paper straws, and will not become soft and bend when exposed to (warm) water, and there will be no residues such as paper scraps mixed into the drink.

    Knock on the blackboard: Most importantly, the PLA straw can suck up the pearl taro coconut... It will not get stuck in paper straws due to adhesion.

    Environmental protection: PLA, like paper straws, can be completely degraded by microorganisms in nature after use, and eventually carbon dioxide and water will be generated.
