Biodegradable Plastic Bags: What Are They?

Biodegradable plastic bag is a hot subject of environmental protection. National’s Government propagandize everyone use these bags instead of normal bag; further they issue policy to forbid the using plastic without biodegradable additive.

What are Biodegradable plastic bags?

They are the kind of polyolefin plastic bags which are created using materials that allow the bag to complete decompose after a period of time by the action of naturally-occurring micro-organisms such as bacteria, fungi, or controlled degradation though the incorporation of prodegradant to undergo accelerated oxidative define degradation initiated by natural light, heat and oxygen. They are disintegrated totally within 3 months to 5 years.

Classification

There are many ways to classify the pvoh film suppliers biodegradable. One of the ways is degradable condition, there are two main types: Biodegradable plastic bags and Degradable plastic bags.

Bio-degradable is made from farmed products like cornstarch and additive; they are decomposed in the aerobic condition, so they can not degrade in natural environment. It is not a good choice for the landfill in natural environment.

If bio-degradable bags are not a good choice for the landfill, degradable bags are a perfect choice; with other name oxo-degradable bags are made from petroleum-base and additive. They are decomposed automatically under natural condition with oxygen, light and heat. It is great solution to settle huge landfill.

Beside protect environment, the biodegradable plastic bags are used to create energy resource. It break down to elements carbon dioxide, water and large of metal. So that the bioreactor or wet landfill are designed to encourage the break down of organic matter and capture the methane emitted for energy generation.
