New water soluble film technology optimizes packaging solutions
Source:Adsale Plastics Network    Editor:JK    Date:14.Oct.2020

Cortec has announced that the patented EcoSol water soluble pouches will be available from its European bioplastics plant located in Croatia. This will enable prompt delivery of custom made pouches to its European and Asian customers.


EcoSol technology represents latest generation of packaging solutions. This water soluble, biodegradable, polyvinylalcohol (PVOH) film is suited for various packaging applications.


Water soluble PVOH bags, sachets, or pouches created from this film provide a convenient, safe, and economical delivery system for a wide range of products; including detergents and cleaners, degreasers, concrete additives, pigments, biocides, water-treatment products, agricultural products and others.


After immersion EcoSol dissolves in water leaving a harmless, non-toxic, aqueous solution of polyvinyl alcohol.

EcoSol film has good organic solvent resistance, which allows EcoSol pouches and bags to be used not only for dry powders, but also for liquid products. This innovative film offers very good mechanical properties: tensile strength, tear strength and puncture resistance. These properties allow EcoSol to be used in a wide variety of rigorous applications. Products packaged in EcoSol can be thrown into a treatment area without removing the film.


After few minutes of immersion at the specified temperature, EcoSol dissolves in water leaving a harmless, non-toxic, aqueous solution of polyvinyl alcohol releasing the packaged product to do its work. 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.


Mechanical properties of EcoSol packaging conform the normative of ASTM D 882-02 for Braking factor, Tensile Strength of break, Elongation and Yield Strength. Its Tear Strength is tested according ASTM D 1922-06a and Dart Drop Impact resistance - per ASTM D 1709-04.


EcoSol can be used for packaging of:


  • Detergents and cleaners

  • Degreasers

  • Concrete additives

  • Pigments

  • Water-treatment products

  • Biocides

  • Agricultural products

  • Soil remediation

  • Bathing products

  • Cosmetic industry (disposable cases)

  • Laundry bags for hospitals
