It is an environmentally friendly material that can dissolve completely upon contact with water. Unlike traditional trash bags, it can be directly disposed of in toilets or food waste bins along with its contents, greatly simplifying the waste sorting process. The core technology of water-soluble trash bags lies in PVA (polyvinyl alcohol) molecular material, which achieves full biodegradation through the biochemical mechanism of water molecule penetration and decomposition. Upon contact with water, the hydrogen bond network of the molecular chains is disrupted, causing the bag's molecular chains to soften and disintegrate, ultimately dissolving completely. Its primary raw material, PVA, can be fully decomposed by microorganisms in the natural environment into carbon dioxide and water
