Blowing PVA film as easy as blowing PE film
Water-soluble PVA materials are modified by blending polyvinyl alcohol(PVA) and some other water-soluble additives.
These materials are environmentally friendly materials with water solubility and biodegradable properties, they can be completely dissolved in water.
In the natural environment, microbes ultimately break the products into carbon dioxide and water.
After returning to the natural environment, they are non-toxic to plants and animals.
