Abstract: An adhesive tape system, for opening cardboard packaging, having an adhesive tape A furnished on at least one side with an adhesive coating and having a film carrier, the film being a polyolefin film oriented monoaxially in the longitudinal direction of the strip, and the film comprising a mixture of an olefinic polymer and a polar nonolefinic polymer. The adhesive tape system also has an adhesive tape B furnished on at least one side with an adhesive coating and having a film carrier, wherein the adhesive tapes A and B are disposed one above the other.

Abstract: The invention relates to adhesive tape having a support made of a film, an adhesive mass being applied to at least one side thereof. Said film is a monoaxially stretched film which is made up of at least 50 wt. % of a polypropylene homopolymer and 10-25 wt. %, preferably 15% of a copolymer made from ethylene and 2-6 mol % of an ?-olefin. The ?-olefin is a diene having at least four carbon atoms, the adhesive mass contains a polyisoprene rubber and one or more adhesive resins, the rubber/adhesive resin weight ratio being higher than 1.10.

Abstract: Disclosed is an adhesive tape comprising a carrier consisting of a foil, to one side of which an adhesive substance is applied. The adhesive substance contains a polyisoprene rubber and one or more adhesive resins, the weight ratio of the rubber to the adhesive resin being greater than 1.10. A silicone-based separating agent is applied to the side of the carrier that is not provided with the adhesive substance.
