The film variant of PVA is used mainly for dissolvable packaging. It is heat sealable and is therefore convenient for packaging products in dissolvable bags. It is used for sanitary laundry bags that dissolve in the washing machine. It is also used for fishing bait, where a PVA-bag filled with bait is put on the hook. When the bag lands on the river bottom it breaks down, leaving the hook surrounded by bait.

 

The film is available in many grades. Dissolution times, dissolution temperature, strength, stiffness, and cosmetics can be modified. It is sold as film, but semi-finished products such as bags are also available.
