Designed for Recycling

Successfully creating sustainable and recyclable packaging starts during the design phase: The right choice of adhesive significantly influences what can be done with the package at the end of its primary use. With its RE range of adhesives and coatings designed for recycling, Henkel enables packaging to go beyond current functionalities – to create flexible packaging that has recyclability “built in”. Products in this range must fulfill stringent external testing requirements for sustainability. 

“The use of certified adhesives according to recognized test protocols is extremely important, as there are differences in the recycled materials in terms of their processability as well as their physical properties,” says Elodie Picard, Head of Sustainability Packaging. “Ensuring our customers can reach their sustainability goals is one of our top priorities, which is why we work together with independent testing institutions to certify our solutions.”

Comprehensive Range of Recycling Compatible Adhesives for Flexible Packaging

In recent years, Henkel has focused on the development of solutions that support the recycling process and now has the industry's most comprehensive range of recycling compatible adhesives making up our “RE Range”. The portfolio of RE adhesives includes both solvent-free and solvent-based adhesives and covers the main performance segments. The range of recycling compatible products also include RE Range coatings for various applications. The recycling compatibility of all Henkel RE Range products is certified by recognized certification institutes.
