Description of Film Blowing Material
Polylactic acid, also known as polylactide, belongs to the polyester family. Polylactic acid is a polymer obtained by polymerization with lactic acid as the main raw material. The raw materials are sufficient and renewable, mainly corn, cassava, etc. The production process of polylactic acid is pollution-free, and the product can be biodegradable, realizing the circulation in nature, so it is an ideal green polymer material. Good mechanical and physical properties. Polylactic acid is suitable for a variety of processing methods, which is convenient for processing and widely used. At the same time, it has good tensile strength and ductility, and polylactic acid can also be produced by various common processing methods.Benefits of Film Blowing Material
- PLA pure resin is a translucent and opaque granular amorphous polymer, which has a comfortable feel and melting point. It is 175-180 degrees, and its glass transition temperature is 50^65 degrees.
- PLA is composed of starch and has good biodegradability, which can be completely destroyed by microorganisms in nature after use. Degradation, the final generation of carbon dioxide and water, does not pollute the environment, which is very beneficial to environmental protection, and is recognized as an environmentally friendly material.
- When PLA is incinerated, it will never release toxic gases such as nitride and sulfuric acid.
