This packaging film is water soluble
EcoSol® is a PVOH (polyvinyl alcohol) film (photo) that dissolves in water in minutes. It can be made into bags, pouches and sachets of many different sizes to create an efficient delivery system for a wide range of products, including the following: detergents; concrete additives; water-treatment chemicals; agricultural treatments; and bathing products. Packaging products in EcoSol pouches allows precise dosing and avoids the messiness associated with trying to measure and apply powder products — especially in windy conditions. EcoSol is especially beneficial for packaging chemicals because it eliminates the need for direct handling. Although EcoSol is designed to break down in contact with water, it can be stored for two years if kept in dry conditions at room temperature in the original barrier bags. After immersion, EcoSol dissolves in water, leaving a harmless, non-toxic, PVOH solution and releasing the packaged product. Once the solution of PVOH comes into contact with common microorganisms, conversion to carbon dioxide and water takes place within about 30 days. — Cortec Corp., St. Paul, Minn.
