PLA Advantages Introduction

- Jan 12, 2020-

PLA is a new type of biodegradable material made from starch raw materials proposed by renewable plant resources such as corn. The starch raw material is made into lactic acid through a fermentation process, and then converted into polylactic acid by chemical synthesis. It has good biodegradability, can be completely degraded by microorganisms in nature after use, and finally produces carbon dioxide and water, which does not pollute the environment. This is very beneficial to the environment and is recognized as an environmentally friendly material.

PLA has the best tensile strength and ductility, and polylactic acid can also be produced in a variety of common processing methods.

PLA film has good gas permeability, oxygen permeability and dioxane, and it also has the property of isolating odor.


When polylactic acid (PLA) is incinerated, its calorific value is the same as that of incinerated paper. It is half of the incineration of traditional plastics, and incineration of polylactic acid will never release toxic gases such as nitrides and sulfides. The human body also contains lactic acid in the form of a monomer, which indicates the safety of this decomposable product.
