Compostable PLA Film for packing
PLA (polylactic acid)
PLA is a new kind of biodegradable material, the use of renewable plant resources (such as corn) of starch material. Getting glucose starch raw materials by saccharification, and through glucose and certain strains of fermentation to make high purity "lactic acid, then through chemical synthesis method to synthesize polylactic acid of certain molecular weight. It has good biodegradable properties, that can be degradated completely by microorganism of the nature after using, finally generated carbon dioxide and water won't pollut the environment and cause the greenhouse effect. it is is recognized as environmentally friendly materials and very good for the environment.

bioplastics Biodegradable ECO Friendly PLA film
PLA is derived from renewable resources, such as corn starch or sugarcane. PLA polymers are considered biodegradable and compostable. PLA is a thermoplastic, high-strength, high-modulus polymer that can be made annually from renewable sources to yield articles for use in either the industrial packaging field or the biocompatible/bioabsorbable medical device market. Bacterial fermentation is used to make lactic acid, which is then converted to the lactide dimer to remove the water molecule which would otherwise limit the ability to make highmolecular weight polymer. The lactide dimer, after the water is removed, can be polymerized without producing water.
