Biodegradable Plastic Bags are produced from Biodegradable Resins.
These resins are plastics that can naturally decompose with the aid
of microbial organisms. Biodegradable plastics break down cleanly,
in a defined time period, to simple molecules found in the environment
such as carbon dioxide and water.
The properties of biodegradable resins which are used to produce
biodegradable plastic bags are as follows;

This grade resin is a compostable and biodegradable plastic based
on a blend of thermoplastic starch (TPS), aliphatic polyesters (AP)
and natural plasticizers. This grade of resin is compatibilised to
offer a high level of mechanical strength, outstanding elongation
properties and toughness. The resin is based on corn starch which
is renewable material.
Application Areas:
Compostable Bags
Shopping Bags/Check-out bags
Garbage Bags
Leaf litter Bags
Green Bin Liners
Overwrap packaging
