  • Adhesive tapes
    Patent number: 4699816
    Abstract: In making pressure sensitive tapes having an olefinic polymer or copolymer support, in particular polypropylene, or a support of coextruded film of an olefinic polymer and of another polymer or copolymer, modification of the adhesive by addition of a mineral or synthetic oil brings about a substantial reduction of noise upon unwinding the tape. Said modification can be combined with modification of the release coat provided on the back of the tape and/or with special treatment of the support back.
