What are the new environmentally friendly materials and degradable packaging bags?

- Jun 13, 2020-

In order to promote green and environmentally friendly packaging, the packaging bags can be quickly and completely degraded without pollution under natural conditions after being discarded. Professional flexible packaging manufacturer Shanghai Yifu Packaging introduced advanced plastic packaging bags (PE, PP, BOPP, PS, PVA, PLA materials) D2W oxidative biodegradation technology, EPI degradation technology, TDP degradation technology and other advanced production processes.


1. D2W oxidized biodegradable packaging bag

Shanghai Yifu Packaging uses the world's advanced and environmentally friendly D2W oxidized biodegradable plastic technology to produce degradable packaging bags. This technology is a mature technology (first oxidation followed by biodegradation) passed the American ASTM6954 standard. It can be used in large quantities 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 there will be no residual organic polymers in the soil among.


The principle is to add several mineral salt ion components in the particles through a little (usually 1%) D2W oxidative biodegradation, so that the packaging bag will be broken into small fragments under oxygen, and this situation will continue until the small The fragments are broken down into extremely tiny substances with a molecular weight of less than 5000 that can be completely decomposed by microorganisms in the general biological environment. At this time, 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. As a fully oxidized biodegradable additive, EPI has the reputation of being the most cost-effective on the market. The use of EPI degradable packaging bags generally only increases the cost by 10-20%, but the cost of selecting new materials may increase by 1-2 times.


EPI biodegradable packaging bags are the world pioneer and leader in oxidized biodegradable plastic technology.


3. TDP degradable packaging bag


TDP degradable packaging bags can be oxidized and decomposed under natural conditions such as ultraviolet light, heat and pressure. The plastic packaging bag is broken into pieces of low molecular weight, and then decomposed by microorganisms, and finally converted into carbon dioxide, water and organic matter. During the entire decomposition process, no toxic substances will be released.


TDP is a 100% environmentally friendly plastic degradation technology.
