ABSTRACT:
A pellicular laminate comprising: a web of polypropylene film, on at least one surface of which is a layer of polyurethane; a metal, preferably a ductile metal such as gold, which has been deposited on that surface of the polyurethane layer farthest away from said web, by sputtering; a layer of adhesive on the exposed metal surface; and a release liner in the form of a film of polyester or the like covering, but separable from, said adhesive layer. With the web and the release liner removed, the remaining pellicular laminate is useful in shielding structures from electromagnetic radiation by applying the laminate to the surface of the structure to be shielded with the adhesive side towards the structure.
