Abstract

1416626 Plastics films BRITISH CELLOPHANE Ltd 19 March 1974 [30 March 1973] 15420/73 Heading C3P Plastics films having low adherence comprise 1 to 50 weight per cent of glass spheres of diameter 4 to 105 microns. The plastics material may be polyethylene, polypropylene or polyvinyl chloride. The films may be prepared by extruding through slot die, or as blown tubular film. Preferably the plastics material is premixed with an inert wetting agent, e.g. ethylene glycol or liquid paraffin, which is dissipated at the extrusion temperature. The films may be used as separators for two-side coated pressuresensitive adhesive tapes and uncured rubber sheets, as protective coatings on metal rods, and as carriers for pressure-sensitive adhesive labels.
