Symphase Technology, an innovative and patented process for the creation of transparent oxygen barrier layers based on the vapour deposition of melamine has been launched by Stamicarbon BV, the DSM Licensing Centre, in The Netherlands.

It has applications for electrical, medical and disposable products.

Branded as Freshure Coatings, it is now available for licensing in flexible packaging, particularly food packaging.

The presence of gases such as oxygen in food packaging can be detrimental to product freshness.

To protect packaged foods and liquids from oxygen ingress, plastic films for food packaging are today usually provided with barrier coatings - some of which have limitations in terms of clarity, cost-effectiveness, or environmental issues.

DSM's new Symphase technology offers a genuine alternative pathway for the creation of such barriers with its FreshureCoatings, available either as a stand-alone high-gas barrier coating, Freshure - Single Coat, or as a top coat for oxide coated or metallised films, Freshure - Top Coat.
