Abstract: For pressure sensitive adhesive tapes having a film backing of polypropylene or other olefinic polymer or copolymer, the treatment of the non adhesive side before the release coat is applied causes the unwinding noise of the tape to be essentially reduced.

Abstract: The present invention relates to the manufacturing of adhesive tapes having a backing consisting of a polypropylene or other olefinic polymer or copolymer film, one side of which is coated by elastomeric or plastomeric adhesive systems (as applied from solutions, emulsions, in a molted condition, etc., according to the technologies known in the art), the other side being coated with or without corona or flame treatment, with antiadhesive systems which facilitate the unwinding operation of the tape either in the processing and in the application, but at the same time may receive printing inks of the flexoroto-silk-screen type inks suitable for the printing of polyolefinic films. The application of antiadhesive systems which are ink compatible can be carried out either on line, namely during the tape coating process, and on tapes already coated by means of the duly modified printing machine. In some cases there is foreseen the application, immediately after the printing process, of an additional antiadhesive layer to facilitate the unwinding operation and application of the printed tapes.
