ABSTRACT:
A high strength laminate is formed of at least two films of polymeric material each having a predominant grain direction which films are arranged with their grain directions in intersecting or crossing relationship, each adjacent pair of such films being laminated together by an intermediate adhesive bonding layer, an array of filamentitious structures, e.g. parallel continuous filaments, staple fibers, or a split film network, which array has a generally predominating lengthwise direction being disposed within each such bonding layer with the lengthwise direction thereof oriented in an intersecting or crossing relation to the grain directions of both of the adjacent films, the filamentitious structures of such array being substantially free of any adhesive bonding with the intermediate adhesive layer and having a significant stretch capacity.
