Polylactic acid (PLA) is a new type of bio-based and renewable biodegradable material, which is made of starch raw materials from renewable plant resources (such as corn and cassava). 

Starch is saccharified to obtain glucose, which, together with certain strains are fermented to produce high purity lactic acid, which is then synthesized into PLA at certain molecular weight by chemical synthesis. 

PLA has good biodegradability. After disposal, it can be completely degraded by microorganisms in nature under certain conditions to finally generate carbon dioxide and water. The entire process is pollution free. It is very beneficial to protect the environment and is recognized as an eco-friendly material. 

PP products have better elasticity to allow them to rebound faster after bending without leaving much bending marks. PLA products are more brittle than PP, so it is easier to leave bending marks. The density of PP product is lower than that of water, so it will float on the water surface in a cup, while the density of PLA product is higher than that of water, so it will sink into the bottom of the cup. Generally, PP products can withstand a heat up to 248 ℉, so they are not easy to soften and bend when placed in 212 ℉ hot water, while PLA straws produced by GoodBioPak can withstand a heat up to 176 ℉, so the straws are easy to deform and bend when placed in 212 ℉ water. PP product is artificially synthesized by chemical means, so it will give off a pungent smell after burning, while PLA product is made of plant starch such as corn, so it will develop a burnt edge and give off a caramel smell after burning. 

The production of PLA uses less energy and produces 75% less greenhouse gases than the production of conventional plastics.

No, it will NOT biodegradable under normal usage.

Biodegradation only starts when it is buried in a certain composting environment.
