RecyClass approval opens the way for packaging converters and brand owners to improve recyclability of laminated flexible PE-based packaging

Two Dow adhesive systems commonly used for a broad range of polyethylene (PE) film packaging applications have been approved as compatible for mechanical recycling following a rigorous scientific evaluation by the non-profit, cross-industry initiative RecyClass. The approval covers solvent-free MOR-FREE™ L 75-300/ CR88-300 and water-borne ROBOND™ L-350/ CR-3 lamination adhesives1, which will add an adhesive component to the REVOLOOP™ technology platform from Dow.
RecyClass assessments follow rigorous scientific protocols to present a comprehensive evaluation of the recyclability of plastic packaging. The assessments consider all criteria needed for a closed-loop value chain, looking at most used technologies of sorting and recycling infrastructures used in Europe. This verifies that packaging is compatible with recycling or can be effectively recycled.
Dow customers can benefit from this external validation as they apply these adhesives in their mono-material laminated packaging designs. Value chain partners already using these well-established adhesive systems can now have an additional favorable datapoint when designing packaging for recyclability. Using these adhesives requires no changes to existing production processes, nor additional staff training, nor retooling of equipment.
This first European approval for Dow’s adhesives products follows last year’s Critical Guidance Recognitions in the US for three product categories that meet the recyclability protocols of the Association of Plastic Recyclers (APR), in which ROBOND adhesives, OPULUX optical finishes, and SURLYN ionomers from Dow were each recognized for solving packaging design challenges.
The RecyClass Recyclability Approval is yet another important achievement towards Dow’s global sustainability targets. These targets align with the European recyclability targets, such as the EU’s Circular Plastics Alliance, the European Commission’s Plastics Strategy and Circular Economy Action Plan. For example, Dow has committed, by 2035, to close the loop by enabling 100% of Dow products sold into packaging applications globally to be reusable or recyclable. Redesigning today’s multi-material structures into mono-PE ones will allow to enhance recyclability and increase recycling rates. Technologies such as machine direction and bi-axial orientation processes, barrier incorporation and PE-rich thermoforming play a crucial role to accelerate that trajectory.
The approved adhesives will be added into the REVOLOOP technology platform from Dow which is set up to help enable high-quality mechanical recycling through various product offerings in post-consumer recycled resins (PCR), and now also including adhesives, that are engineered to deliver exceptional performance for customers.
