    摘要: The present invention provides a process liner for the preparation of foamed plastic blocks or slabs which exhibits excellent mechanical properties including tear strength, dimensional stability and flexibility while being transparent and allowing easy separation from the produced foam material. The process liner comprising a transparent support polymer film (A) and a transparent peelable polyolefin film (B) provided thereon, wherein the support film (A) has a weight per area of 10-100 g/m2 and is made of a polymer having a melting point of 130° C. or more according to DSC measurement; and wherein the peelable polyolefin film (B) has a weight per area of 10-50 g/m2 and is made of a polyolefin having a melting point lower than the melting point of the polymer of the support film (A) by 10° C. or more. Furthermore, a method for producing the process liner is provided and a process for the preparation of foamed plastic blocks or slabs in a continuous production line.

    摘要: 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.
