  • Patent number: 11655400
    Abstract: A hot-melt adhesive composition is disclosed. The hot melt adhesive comprises a) 25 to 95 wt %, preferably 50 to 85 wt % of at least one polyolefin-based polymer; b) 1 to 75 wt %, preferably 1 to 40 wt % of at least one tackifying resin; c) 0 to 15 wt % of at least one plasticizer; and d) 0 to 30 wt % of at least one additive and/or adjuvant selected from among stabilizers, adhesion promoters, fillers or pigments, waxes, and/or other polymers or combinations thereof, characterized in that the at least one polyolefin-based polymer is a mixture of: a1) at least one first polyolefin-based polymer with a molecular weight Mn of <10,000 g/mol in a quantity of 20 to 80 wt % with respect to the total quantity of polyolefin-based polymer, and a2) at least one second polyolefin-based polymer with a molecular weight Mn of >10,000 g/mol in a quantity of 20 to 80 wt % with respect to the total quantity of polyolefin-based polymer.

  • Patent number: 7166341
    Abstract: Water-soluble or water-dispersible hotmelt adhesives are prepared using graft copolymers produced by graft copolymerizing olefinically unsaturated monomers onto polyalkylene oxides. The adhesives additionally contain at least one resin which improves tackiness and the compatibility of the adhesive components. Other components such as polymers, plasticizers, and additives may also be present. The adhesives are especially suited for use in the labelling of recyclable or reuseable hollow containers. The adhesive may be completely separated from the hollow containers and dissolved in an alkaline washing liquor even at low temperatures.

  • Patent number: 5985074
    Abstract: The invention is an adhesive system for applying wrap around labels to containers. The system comprises a hotmelt pick-up adhesive which is active at the temperature which the label is applied and loses its bonding ability after the adhesive sets and an overlap adhesive for bonding the label overlap. At its application temperature, the pick-up adhesive has significantly higher adhesiveness, measured at its application temperature than at its conventional storage temperature. In addition, the adhesive preferably has a greater affinity for the label than for the container bearing the label. Consequently, the label can be easily removed from the hollow body without leaving residues of adhesive. If, nevertheless, a residual adhesive should remain on the hollow body, it can be dissolved by an alkaline solution.
