Revolutionizing PET recycling with adhesive solutions

PET is the most recyclable plastic in the world - capable of being recycled nearly endlessly without losing its material integrity. As more PET bottles are collected and reprocessed into new packaging, the demand for high-purity PET flakes increases. To ensure optimal quality in recycled PET, the material must remain clear, color-stable, and retain its barrier properties. However, traditional hot melt adhesives used in bottle labeling often compromise this. With removal rates as low as 12–30%, residues from conventional adhesives can cause hazing, discoloration, and degrade the purity of the recycled material. 

Our innovative adhesive TECHNOMELT EM 335 RE is specifically designed for PET bottle labeling and disperses completely in the caustic soda bath during recycling. With a removal rate of 98%, it ensures that labels separate cleanly and leaving behind high-purity PET flakes.
