Pure PVA film has poor water resistance and is greatly limited in practical applications. Therefore, in most cases, it needs to be modified and prepared, such as the preparation of water-soluble film materials whose main raw materials are PVA resin and oxidized starch. In recent years, water-soluble environmental protection bag products with PVA, glycerol, starch, etc. as the main raw materials have been launched, which can be rapidly dissolved in water at 70 \u00b0C, and the degradation rate can reach more than 90% in a composting environment within 180 days.<\/p>\n
