45um Food Packaging PLA Biodegradable Film High Stiffness
45um Food Packaging PLA Biodegradable Film High Stiffness
1. PLA Biodegradable Film Description
PLA Biodegradable Film as green film can be decomposed completely into water and carbon dioxide through burying in soil or composed, because PLA uses the raw material made from plants mainly based on corns or sugarcanes which can be hydrolyzed to dextrose, and then goes to ferment and polymerization, eventually transforms into PLA Shrink Film.
PLA biodegradable film is put ideas of plants-made to develop products for not causing pollution when in recycling process becomes friendly-environment substance H2O and CO2.

4. Advantages
PLA is relatively new and considered the best among shrink sleeve materials for the environment. Not because it is recyclable but rather because it is compostable. In fact, PLA is a corn-based polymer made entirely of plant material.
It is quite stable at ambient temperatures and strong. This makes it Ideal for bundling.
