Cortec® Earns Patent for Compostable Stretch Wrap Technology | Packaging Strategies

Eco Wrap® is a specialty wrapping film that meets the EN 13432/ASTM D6400 standards for commercial composting and was certified industrially compostable by TÜV Austria (#TA8012106218) in 2021. It is extremely elastic and suited for general machine stretch wrapping applications. It can be used to replace conventional plastic stretch wrap with the goal of improving the user’s environmental image and reducing conventional plastic waste when the material is properly disposed in a commercial composting environment. 

Eco Wrap® can be used on most existing automated machines and is easily applied by adjusting (typically increasing) the tension on standard stretch wrapping equipment. It has also been tested on an orbital wrapping machine without breaking, showing greater strength than another film that did not successfully pass the trial. In another case, a coffee distributor who tried Eco Wrap® for stretch wrapping pallets of coffee bags was pleased with the results.

Due to the extensive use of stretch film in today’s world, Eco Wrap® has many exciting possible uses across multiple industries wherever palletization is needed.

While today’s society is placing increasing pressure on industries to conform to new environmental goals, Cortec® has long been on its own mission to use biodegradable or biobased materials where possible. The new Eco Wrap® patent is an excellent example of how that motivation has turned Cortec® into a leader in “green” packaging development.
