Polyvinyl alcohol film is a water-soluble biodegradable film. Its properties include an excellent gas barrier, water-soluble and biodegradable — bring it as one of the most successful eco-friendly materials in recent years. It is universally recognized by environmental protection authorities and public users.
PVA is universally endorsed due to its wider use in various applications as packaging for pesticides, dyestuff, cleanser, detergent and other chemicals biodegradable packaging film for infection control and medical disposal; embroidery and laundry bags applications.
Product Features:
1. It is Eco-Friendly
PVA film is a kind of ‘Green’ packaging material — verified by Microorganism Test. Thus it is non-toxic and doesn't restrict the growth of microorganism and can be biodegraded completely. Once PVA dissolves in water, specific microorganism will cause it to degrade. When being treated with sludge, a PVA solution will be decomposed into water carbon dioxide.
2. It has an excellent water solubility
PVA film has excellent water solubility ancccanent water temperatures and at different solving pace.
3. Water-soluble packaging bag of fertilizer and pesticide
Chemicals used in agriculture are usually highly toxic and cause severe pollution, endanger to health. Therefore people have been paying more and more attention to the materials of agricultural packaging. As PVA packaging film and beg have a unique physical property and biodegradability, they have been more and more popularly used in the packaging of fertilizer and pesticides in recent years.
