The certificate notes that when used with in combination with a polyolefinic substrate (PO) label, “the acrylate-based dispersion pressure-sensitive adhesive has no negative effects on the recycling path for transparent PET bottles”. The adhesive is therefore recyclable according to the CHI standard for PET recycling.
Aquence PS 3017 RE is designed to support PET flake recycling. While conventional methods require an energy-intensive, high-temperature process to completely remove labels, the new adhesive offers excellent wash-off efficiency - even at 65°C for PE facestock. This ensures that labels can be easily removed from bottles using less energy, while increasing the purity and value of recycled PET. In addition to being a sustainable solution for olefinic labels (e.g. BOPP & PE) on wash-off PET bottles, it has excellent food contact approval and water whitening resistance, thus allowing clear labels to stay completely transparent after long time exposure under water.
“We are delighted to receive independent confirmation of how this innovative adhesive can help optimize recyclability and help to support the circular economy,” explains Elodie Picard, Director Market Strategy Tapes & Labels at Henkel. “We are proud to work with our partners across the packaging and recycling value chains to help reduce packaging waste while delivering higher quality recyclates. Indeed, this will be essential to help meet regulations that require a greater proportion of recycled material in plastic packaging. By ensuring that labels and adhesives are part of the solution, Henkel is helping to create a more sustainable future for plastic packaging.”
