RecyClass approves labels on white HDPE bottles as recycling compatible

Since its July release, RecyClass says its Recyclability Evaluation Protocol for Labels & Adhesives applied on high-density polyethylene (HDPE) containers already has been used for the recognition of innovative technologies, marking an advancement in the recyclability of plastic packaging decorations.

RecyClass says the protocol results from testing coordinated by the RecyClass White Packaging Task Force at laboratory and semi-industrial scales. The task force assessed how labels and adhesives behave during the grinding and cold-washing steps of the recycling process. The protocol specifically evaluates the impact of friction on label releasability, providing insights into the recyclability of HDPE containers in real-world scenarios.

With this protocol in place, RecyClass says companies can apply for a recyclability approval for their labels and adhesives used on HDPE containers. It notes that Mentor, Ohio-based Avery Dennison is “at the forefront of innovation” when it comes to label releasability, having become the first company to secure full compatibility approval for three of its products using acrylic emulsion adhesives: PP60 Top Cavitated S7000/S7000ER; PE85 Top White S692N; and PP60 Top White S692N.

RecyClass says it is committed to advancing the understanding of a label’s effect on rigid packaging recyclability and currently is conducting further tests to explore the possibility of extending its evaluation procedure to other plastic streams and label types.

“Thanks to such technological advances and global harmonization of packaging design from the conception phase, the entire plastic value chain will stay ahead of the European legislative requirements enforced by the Packaging and Packaging Waste Regulation (PPWR), facilitating the transition to circular packaging solutions,” RecyClass says.
