Abstract

1276166 Polystyrene films ARCHIBALD EDMESTON & SONS Ltd 8 Sept 1970 [14 June 1969] 30272/69 Heading B5B Films are made from a material comprising polystyrene having a rubber content of substantially 2 to 15% by pouring the material between two heated calender rolls and subsequently cooling the film. The film may be cooled by a concave cooling roll and, between the calender rolls and this cooling roll, there may be located an edgetrimming unit and/or an embossing unit, which is preferably an embossing roll.
