The modified resin of full degradation express bag is a kind of material which needs to be processed by 3-layer co extrusion film blowing machine. It is divided into three kinds of materials.
DP-8122 WTH (Outer layer)
DP-8124 WTH (Middle layer)
DP-8122 NCH (Inner layer)
Compared with other biodegradable resins, express bag special materials have better mechanical properties, excellent puncture resistance and tear resistance, uniform color of finished products, easy to print and good edge sealing performance.
It has the characteristics of easy to be decomposed by microorganisms, natural antistatic and easy to color. It is a completely degradable material, suitable for express bags, logistics packaging bags and other blown film products.

Fully biodegradable plastics are a kind of plastics that can be decomposed into carbon dioxide and water by microorganisms within 180 days under composting conditions. These microorganisms are abundant in nature or composting waste treatment system. After completely biodegradable plastics are discarded, composting is the main treatment method.
