INFORMATION
Polyvinyl alcohol (PVA) is a water-soluble polymer, polyvinyl alcohol film is a green functional material with polyvinyl alcohol as the main body, adding additives such as modifiers, and can be completely degraded by microorganisms in the soil after special processing. It degrades into carbon dioxide and water in a short period of time and has the effect of improving the land. The biggest advantage of polyvinyl alcohol film is water solubility, and the biggest disadvantage is poor water resistance. The reason for the poor water resistance is due to the hydrophilic hydroxyl group (-OH) in its molecule. If the hydroxyl group can be properly blocked and connected to the water resistance group, the water resistance of the PVA film can be improved. Application of PVA water-soluble film
