Polylactic acid (PLA) is another type of bio-based and renewable biodegradable material made from starch materials derived from renewable plant resources (such as corn, cassava, etc.). Polylactic acid (PLA) is the most commonly used. The development of the most mature bio-based materials is favored for its excellent biodegradability and processing properties, and is regarded as a strong competitor to replace petrochemical-based plastic.
First, the advantages of PLA:
1. Low shrinkage and high dimensional accuracy.
2. The molding surface is smooth.
3, the production process is not warped, the product is complete rules.
4, the melting point is low, 195 C can be smoothly extruded.
5. No toxic gas will be generated during production, and no odor will be produced.
6, with good biodegradability, more reasonable environmentally friendly materials.
Food contact approved packaging
PLA is a FDA approved polymer for food contact materials. Common applications for polytechnic acid in packaging include containers, drinking cups, ice cream and salad cups, overpass and blister packs.
