  • Patent number: 8076422
    Abstract: A hot-melt adhesive for resealable packaging, containing 30 to 90 wt. % of at least one copolymer based on ethylene and/or propylene together with C4 to C12-?-olefins, which is obtainable by metallocene-catalyzed polymerization, with a melt index of 5 to 100 g/10 min (DIN ISO 1133), 5 to 50 wt. % of tackifier resins with a softening point of 80 to 140° C., 0 to 15 wt. % of waxes with a melting point of 120 to 170° C., 0.1 to 20 wt. % of additives and auxiliaries, the adhesive having a viscosity of 25,000 mPa·s to 250,000 mPa·s, measured at a temperature of 170 to 190° C.

  • Publication number: 20040180118
    Abstract: A resealable container is provided having a container opening and a rim and a multilayer film covering the container opening and the rim. The multilayer film contains at least an outer layer, a sealing layer facing the rim and a layer of adhesive between the outer layer and the sealing layer. The sealing layer is secured around the rim and contains a weak spot such that when the resealable container is first opened a double bead of said sealing layer remains on the rim in the region of the weak spot. Such resealable containers have improved tear-open behavior and resealability.
