Nanocellulose as a novel biodegradable barrier coating

We have pioneered the use of cellulose polymers and cellulose derivatives to leverage the best of nature in modern material solutions. Our novel, water based, nanocellulose coating technology can offer complete oxygen transmission barrier properties with just a 3-4 micron coating, and are close to resolving the elusive water barrier factor. This disrupts metalization and other non-sustainable solutions that are currently the norm in barrier films, packaging, and tapes.

This is a critical breakthrough since barrier packaging today is not recyclable. Metal or chlorinated multi-layer plastics are not easily seperated and have not useful life when recycled. Even a small fraction of metal or mixed plastic leaves the recyclate brittle and this is send for landfill or incineration today.

We are at proof of principle stage, testing and scaling up our technology on semi-industrial machines to show that this coating technology is ready for the market. We are now able to continously coat plastic sheets. Our vision is initially enhancing plastics while keeping them recyclable, then coating paper, and ultimately launching our own stand-alone biopolymer.

On the left you see two simple PE bags that were heat sealed around a fresh avocado. This image was taken 12 days after sealing... 

The difference is that the bag on the right has a coating of our second generation barrier. Just 0.03mm of our biopolymer is enough to completely seal oxygen and water vapour transmission and preserve this slice of avocado.
