Revolutionising 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, colour-stable, and retain its barrier properties. However, traditional hot melt adhesives used in bottle labelling often compromise this. With removal rates as low as 12–30%, residues from conventional adhesives can cause hazing, discolouration, and degrade the purity of the recycled material. 

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