Abstract

1347681 Coated products DICKINSON ROBINSON GROUP Ltd 19 April 1971 [10 March 1970] 11480/70 Heading B2E [Also in Division B5] A multi-layer sheet packaging material is obtained by transporting a carrier web through a plurality of extrusion stations and depositing thereon successive self-supporting film layers from respective extrusion stations, each layer being chilled to a non-tacky state before applying the next layer, and stripping the multi-layer sheet so formed from the carrier web. There may be intermediate stations at which may be applied treatments, such as to promote adhesion, e.g. by application of adhesive and corona discharge. The layers may be of polyethylene and nylon.
