Barrier coatings for PPWR-compliant packaging solutions

Single-material instead of composite, paper instead of film, fewer layers while maintaining the same level of protection, and the use of recycled materials: If you want to implement PPWR-compliant packaging concepts, you’ll need to balance various requirements. Material efficiency and recyclability are becoming increasingly important. At the same time, product protection, shelf life, and process reliability must remain reliably guaranteed.

Working closely with you, we develop high-performance barrier solutions for your application. You’ll benefit from our many years of experience with gas barrier coatings for flexible films and rigid trays, as well as for paper- and fiber-based materials. We tailor oxygen, water vapor, aroma, and migration barriers specifically to your substrate, packaging structure, required coating thickness, and coating process.

Whether you want to simplify composite structures, switch to monomaterials, or develop new paper-based solutions, we’ll support you from the initial feasibility assessment all the way to an industrially viable packaging solution.

Our thermoformable barrier coatings allow recycled materials to be safely used in PET- or PP-based monomaterial trays in compliance with food safety regulations. They enhance the oxygen and water vapor barriers of packaging, thereby helping to extend the shelf life of sensitive products.

Produce your own barrier film: Instead of purchasing a special barrier film for every application, coat standard monomaterial films specifically with the barrier your packaging requires. This gives you greater flexibility in material selection and reduces your reliance on pre-manufactured barrier films.

In recent studies, the oxygen barrier of thermoformed trays was increased by a factor of 4 compared to state-of-the-art materials with a barrier layer. Our barrier coatings retain their functionality even under severe forming conditions, thereby supporting demanding applications with high product protection requirements.

For flexible packaging such as stand-up pouches, lid films, and three-side-sealed bags, we develop coating solutions that deliver high barrier performance while maintaining high recyclability. These systems can be adapted to various film materials and existing coating processes.

Achieve the desired barrier performance with significantly thinner coating layers: Our composite coatings offer up to ten times higher oxygen barrier performance than standard barrier coatings on the market. This allows the required barrier layer to be significantly thinner while maintaining the same performance.

In addition, the coatings provide a migration barrier and allow you to use recycled materials in flexible packaging. This enables you to meet future requirements for the use of recycled materials while ensuring high standards of product protection.
