  • Patent number: 11485882
    Abstract: A label which is attachable to object surfaces includes a pressure sensitive adhesive layer having a coat weight equal to or higher than 10 g/m2. The adhesive layer has a composition which is free of alkylphenol ethoxylate and has been selected to comprise emulsion polymerized, water-dispersible acrylate polymer and non-ionic copolymer based on polyethylene glycol and polypropylene glycol such that when the adhesive layer is subjected to paper recycling process conditions, the adhesive layer resists disintegration into small fragments.
    Type: Grant
