  • 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.
