【 Abstract 】 :
In order to advocate green and environmentally friendly packaging, the packaging bag can be quickly and completely degraded without pollution under natural conditions after being used and discarded. Professional flexible packaging manufacturer Goolien Packaging has introduced advanced plastic packaging bags (PE, PP, BOPP, PS materials) D2W oxidative biodegradation technology, EPI degradation technology, TDP degradation technology and other advanced production processes.

In order to advocate green and environmentally friendly packaging, the packaging bag can be quickly and completely degraded without pollution under natural conditions after being used and discarded. Professional flexible packaging manufacturer Goolien Packaging has introduced advanced plastic packaging bags (PE, PP, BOPP, PS materials) D2W oxidative biodegradation technology, EPI degradation technology, TDP degradation technology and other advanced production processes.
1. D2W Oxidized Biodegradable Packaging Bag
Goolien packaging uses the world's advanced and environmentally friendly D2W oxidized biodegradable plastic technology to produce degradable packaging bags, which is a mature technology through the U.S. ASTM6954 standard (first oxidation and then biodecomposition). It can be widely used in PE, PP, BOPP, PS and other packaging products, and after these packaging bags are discarded, they can be naturally decomposed into water, carbon dioxide and cellular biomass in the general environment, and no organic polymers will be left in the soil. The principle is through a small amount (usually 1%) of D2W oxidation biodegradation of several mineral salt ions in the addition of particles, so that the bag in the presence of oxygen to split into small fragments. This will continue until the small fragments break down into extremely small substances with molecular weights of less than 5,000 that can be completely broken down by microorganisms in the general biological environment, at which point the plastic is no longer plastic.
2. EPI Degradable Packaging Bag
Many large supermarkets in North America and Australia have specified products containing EPI biodegradable plastic additives, EPI as a completely oxidized biodegradable additive in the market has the best cost-effective reputation. The selection of EPI degradable packaging bags generally only increases the cost by 10-20%, but the cost of new materials may increase by 1-2 times. EPI biodegradable packaging bags is the world pioneer and leader in oxidative biodegradable plastic technology.
3. TDP degradable packaging bag
TDP degradable packaging bag can be oxidized and decomposed under natural conditions such as ultraviolet light, heat and pressure. The plastic packaging bag is broken into low molecular weight fragments, and then decomposed by microorganisms, and finally converted into carbon dioxide, water and organic matter. During the decomposition process, no toxic substances are released.
TDP is a 100% environmentally friendly plastic degradation technology.
