Product Introduction

In the past ten years, the global scientists develop all kinds of decomposable raw material for plastics, the chemical additive, the auxiliaries unceasingly. To decreases the influence and pollution of environment due to the plastic waste. As a result of the use of plastic bag belongs to the disposable use product, but non- durable product. Although the past major part of decomposable plastic bag has the certain help to the natural environment, the shortcoming is:

1) Difficulty with controls the resolving time: due to the carrier resin is made by natural material (e.g. starch, maize meal...etc.), the resolving time is easily influence by the environment factor.

2) Decrease the plastic characteristic:
adds the chemical additive or the auxiliaries in the plastic bag, weaken the pulling force of plastic bag. The thickness of these plastic bag is relativity thicker than the common plastic bag 30%. So the usage of plastic material is increase.

3) Geographical environment: some photo chemical decomposed plastic bags can only decompose under sunlight, but it buried in junkyard will lose its degradable capability.

4) Degradable proportion: because the chemical additive or the auxiliaries in plastic bag can only decompose, but other part of plastic bag is plastic material. In other words, add 30% the chemical additive or the auxiliaries in plastic, only these part can decompose, other plastic parts cannot decompose.

5) The quality of finished product:
because the chemical additive ingredient is heavier by 5%-30%, it will influence the transparency of the finished product in the certain degree.

6) The price of finished product: because add the chemical in plastic bag and the thickness of plastic is increase, so the price of finished product is increased by approximate 50%.

plastic additive uses the chemical method, it can control the resolving time of plastic bag accurately. When plastic additive mix in plastic product, it can preserve the durable merit of plastic in appoint time. The plastic bag will be oxidized and decomposed naturally after the availability date. plastic additive cannot influence the pulling force and the transparency of plastic bag. In any condition, it can fully decompose, especially suitable for the following plastic film,

LDPE - Low Density Polyethylene

HDPE - High Density Polyethylene

LLDPE - Linear Low Density Polyethyene

MDPE - Medium-density Polyethlene

PP - Polypropylene

It can be decomposed by the following four environmental factor:
Photo-degradation: due to light
Hydrolysis-degradation: due to water
Bio-degradation: due to living organism
Oxidative-degradation: due to reaction with oxygen

Under junkyard environment, sunlight (UV), solar thermal energy, water and bacterium, during the oxidization, the molecular weight of plastic gradually bursts, firstly the plastic bag is broken, then it decomposes to the scrap, finally it decomposes to water (H₂O), carbon dioxide (CO₂) and toxic free biomass. After the test report, the molecular weight is below 2,500Mw, it can be eaten by bacterium. is global patent formula, development in U.S.A., confidence guarantee.

Relies on the US technology and the guarantee, fully degradable plastic product are deeply supported by the government apparatus and the enterprise in recent year. In ecological environmental protection consciousness, accord with 100% environmental protection and the price is satisfied by customer's request.
