Water-soluble film resists organic solvents

Cortec® offers EcoSol®, a water-soluble, biodegradable polyvinyl alcohol (PVOH) film suited for various packaging applications. Bags, sachets, or pouches created from this film protect a variety of products during delivery, including detergents and cleaners, degreasers, concrete additives, pigments, biocides, water-treatment products, and agricultural products.

The film is highly resistant to organic solvent and offers good tensile strength, tear strength, and puncture resistance. After a few minutes of immersion in water at the specified temperature, the environmentally safe film dissolves in water, leaving a nontoxic, aqueous solution of polyvinyl alcohol.

Once the liquid solution of PVOH comes into contact with common microorganisms, such as those found in water-treatment plants, conversion to carbon dioxide and water takes place within about 30 days.
