Coveris multilayer film with sealing capabilities

Coveris has developed a multilayer film with sealing capabilities that enables current polythene-lined packaging trays to be more easily recycled.

Technical engineers have worked to formulate a thin, multilayer, polyester barrier solution that enables plastic lidding film to be heat-sealed direct to the packaging tray through capabilities within the material. Traditionally, film is sealed to the pre-lined tray using a polythene (PE) bonding layer, which currently makes the PET tray more unlikely to be recycled.

The finished format offers a sustainable, high-quality, high-performance product for tray packed goods.

The packaging has been developed in collaboration with Tulip. The product is formulated using nine-layer extrusion technology and converted to form a high-performance laminate, and delivers the same, if not better, seal integrity, visual clarity and shelf-life benefits as before. The film also uses burst-peel functionality to offer a more consumer-friendly, easy-open product.
