Cortec Adds to Biodegradable Line

ST. PAUL, MN | Cortec announces EcoSol, a water-soluble, biodegradable, polyvinyl alcohol (PVOH) film said to be well suited for packaging applications that include bags, sachets, or pouches for many products

Film is said to have excellent organic solvent resistance, allowing pouches and bags to be used not only for dry powders but also for liquid products. Also reported to offer offers good mechanical properties including tensile strength, tear strength and puncture resistance.

This product joins company’s line of biodegradable materials, Company says after a few minutes of immersion at the specified temperature, the environmentally safe film dissolves in water leaving a harmless, non-toxic, 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. Bags are chemically resistant to mineral, vegetable, and animal oils as well as aliphatic hydrocarbons and ethers, esters, and ketones.

EcoSol bags were a part of a “green” initiative conducted by Wright Patterson Air Force Base, where all products and processes were being evaluated for environmental impact. When the base officials decided to change applications for cooling and heating systems to “green” and safer alternatives, they selected Cortec's Boiler Lizard and Cooling Loop Gator packed in EcoSol bags. Company says the result was a clean, reliable, efficient, and environmentally safe solution that provided excellent corrosion protection.
