Covestro Partially Biobased Barrier Coating Resin Recyclable Packaging Covestro introduces its latest innovation solution, a partially bio-based barrier coating resin, Decovery® CQ 6010, which helps ‘close the loop’ for recyclable paper packaging.

Decovery® CQ 6010 is made with 37 percent plant-based and transparently sourced ingredients, such as bark, castor beans, and corn. This substantially reduces its carbon footprint in comparison to virgin PE and standard fossil-based coatings.

Exhibits Moisture Barrier for Protection

Many packaged food products are sensitive to moisture, so controlling the moisture vapor transmission rate (MVTR) is critical to maintain the quality of the food. To protect the product inside a package, paper and board food packaging is often laminated with polyethylene (PE) or aluminum.

The materials limit the packaging’s recyclability, meaning it often ends up going to landfill or being incinerated. Covestro’s innovative barrier coating resin reduces waste by replacing these PE or aluminum layers in paper food packaging to make it recyclable.

By enabling low MVTR values, Decovery® CQ 6010 provides a moisture barrier to protect the food, as well as delivering good oil and grease resistance. This makes it suitable for use in packaging for a wide range of food, from dry high-fat products such as chocolate bars to ice cream, frozen food, and fresh fruit.

Davide Reverdito Bove, sector marketing manager Printing & Packaging at Covestro, said, "While PE laminates do a good job of protecting food contents, they make food packaging virtually impossible to recycle. As a result, a lot of them go to landfill or are incinerated. Our new resin is a game-changer in addressing this issue.

It gives food producers and packaging makers an excellent opportunity to deliver the protection that packaging requires while having less impact on the environment. That’s just one reason why we are so proud of this new coating, and so excited to be telling the world about it," added Bove.
