Environmentally Friendly Corn Based PLA Plastic Film , Shrink Wrap Plastic Rolls
1. Environmentally Friendly Corn Based PLA Plastic Film , Shrink Wrap Plastic Rolls Introduction
PLA is a biodegradable plastic produced from renewable resources. For this reason, it is more environmentally friendly than most alternatives. It tends to be more expensive than most conventional shrink labels. Shrink results tend to be less repeatable than with petroleum-based polymers, meaning a more robust process is necessary.

5. Advantages of PLA
One of the major advantages of PLA is its biodegradable nature and the sustainable process by which it is made, making it the environmentally friendly choice of plastic. Under the right circumstances, PLA can break down into its natural elements in less than a month in contrast to the centuries it will take for traditional plastics to decompose.
The process by which PLA Is made is also more environment-friendly.
PLA is a thermoplastic, meaning it will turn into a liquid in its melting point of 150 to 160 Celsius. A nifty feature of thermoplastics is that they can be heated, set upon cooling, and reheated again to form other shapes without any degradation. In contrast, a thermosetting plastic (such as epoxy or melamine) can only be heated and molded once, but the resulting product can no longer be reheated as it will just burn. This property of PLA makes it a desirable material for recycling.
PLA can be broken down to its original monomers by a thermal de-polymerization process or by hydrolysis. The resulting monomer solution can be purified and used for subsequent PLA production without any loss of quality. Should a material made from PLA be incinerated, no toxic fumes will be generated.
