PLA(Polylactic Acid)

PLA takes annually renewable resources – corn, cassava and other plants as
raw material. After fermentation by microorganisms, lactic acid will be extracted,
then PLA will be produced through a process of refining, dehydration polymerization,
high temperature pyrolysis and final polymerization. PLA has excellent
biodegradable property. After disposal, within one year, it can be degraded
into carbon dioxide and water by microorganisms in the soil, and do no harm to our environment.

PLA is a kind of aliphatic polyester with basic characteristics of general
macromolecular materials.

PLA has good mechanical properties, low shrinkage, and is competent to the
application of most synthetic plastics, also it’s widely used in the production
of package materials, disposable tableware, household electrical appliance shell,
fiber, 3D supplies etc.

Because PLA derives from renewable plant resources but not the petroleum-based
traditional plastics, so it is energy-saving and enviromental protection,
and PLA is considered to be the most promising new “ecological material”.
