A composite web comprises a film of plastics or other material laminated to a reinforcing layer formed by a network of tapes which extend in zigzag fashion back and forth across the laminating film with their points of reversal within the confines of the film edges so as to be covered by the film. If there are two equally wide laminating films, one on each face of the reinforcing tape layer, the films may be offset to overlap one another laterally and the width of the tape layer exceeds that of each film by the amount of overlap, whereby the points of reversal of the tapes are covered by one of the films along one longitudinal edge of the web and by the other film along the other longitudinal edge of the web. |
