Polylactic acid (PLA) uses corn, cassava and other crops as raw materials and has excellent biodegradability. It can be degraded by microorganisms in the soil within half a year to one year after being discarded, and does not pollute the environment.

The raw material of the PLA degradable straw is derived from plant starch, and the matrix material has a wide range of resources. In the case of high crude oil prices and depletion of oil reserves, PLA drinking straws have obvious environmental advantages and obvious social benefits, and will gradually replace traditional polypropylene drinking straws.
