The approval makes way for packaging converters and brand owners to improve the recyclability of laminated flexible PE-based packaging, the company says.
A pair of Dow adhesive systems commonly used for a broad range of polyethylene (PE) film packaging applications have been approved as compatible with mechanical recycling, following what the company says is a rigorous scientific evaluation by the European nonprofit, cross-industry initiative RecyClass.
Dow says the approval covers its solvent-free Morfree L 75-300/CR88-300 and water-borne Robond L350/CR-3 lamination adhesives, which will add an adhesive component to its Revoloop technology platform.
According to Midland, Michigan-based Dow, which has European headquarters in Horgen, Switzerland, 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 to verify that packaging is compatible with recycling or can be effectively recycled.
Dow says its customers can benefit from this external validation as they apply these adhesives in their mono-material laminated packaging designs. The company adds that value chain partners already using these adhesive systems can now have an additional favorable data point when designing packaging for recyclability, and use of the adhesives requires no changes to existing production processes nor additional staff training or retooling of equipment.
Fabrizio di Gregorio, technical director at Brussels-based Plastics Recyclers Europe, says, “Innovation is key in furthering the circularity of plastics, but at the same time, it is essential to ensure that these new packaging technologies comply with existing recycling systems. This is exactly what the RecyClass recyclability approval awarded to Dow’s technologies proves. We are delighted to work with companies like Dow and strive to support companies in implementing recyclability principles into the core of their strategic decisions.”
Izzat Midani, Dow Packaging & Specialty Plastics EMEA marketing manager, says sustainability is front and center in the company’s innovation strategy and the main focus of the industry.
“I am very proud that two different technologies in our laminating adhesives portfolio have been approved for mechanical recycling by RecyClass,” Midani says. “This enables our customers and brand owners to reach a wider scope of applications and performance requirements while facilitating packaging recyclability, which will be crucial as they strive toward achieving ambitious sustainability targets.”
The approved adhesives will be added into Dow’s Revoloop platform, which is set up to help enable high-quality mechanical recycling through various product offerings in postconsumer recycled resins (PCR), and now also including adhesives, that are engineered to deliver exceptional performance for customers.
The company says this first European approval for the adhesive products follows last year’s critical guidance recognition in the U.S. for three product categories that meet the recyclability protocols of the Association of Plastic Recyclers (APR), Washington. Robond adhesives, Opulux optical finishes and Surlyn ionomers were each recognized for solving packaging design challenges.
We remind, Dow announced the launch of V PLUS Perform™ next, an evolution of its legacy V PLUS Perform™ polyurethane technology for insulated metal panels. The offering brings together the high-performance energy efficiency and fire safety features of V PLUS Perform™, with low carbon and circular ingredients designed to customer specifications.
