Biodegradable Supermarket Shopping Bag helps environmental protection

Since it is a biodegradable environmentally friendly plastic bag, we must say its degradation performance. The degradation process of dual degradation technology products is mainly divided into two major steps. The first step is to use and discard the product under the stimulation of light, heat, oxygen and other conditions in the natural environment. , Under light/thermal oxygen degradation, apparently it appears to be broken, cracked, tensile strength decreased, inherently long-chain polyethylene fractured, molecular weight decreased, and oxygen-containing carbonyl groups appeared in the structure. This is a broken and crushed material that is not polyethylene in the true sense, causing structural changes and molecular weight changes, and has become oxygen-containing oligomers; in the first step, the product can be decomposed by environmental microorganisms in the natural environment. Water, carbon dioxide and soil organic matter. Because microorganisms can use substances with a molecular weight of less than 10,000, the product's molecular weight is reduced to less than 10,000 after pre-degradation, and at the same time it changes from hydrophobic to hydrophilic. The surface can be attached to the growth of microorganisms, which is also a carbon source, so it can be decomposed by microorganisms. Back to nature.
