Abstract:
1. A laminate comprising at least one ply A and at least one ply B each formed of at least one monofilm or multifilm and comprising a thermoplastic polymer material of which the polymer material of at least one ply A is cold-orientable has a wavy or fluted configuration while at least one ply B is not waved, the fluted ply A being adhesively bonded to a first side of at least one ply B in bonded zones along at least some of the crests of the flutes of a first side of the fluted ply A, the thickness of the fluted ply A being of a variable thickness established by solid-state attenuation of the fluted ply A in transversely spaced apart elongated first attenuated zones extending parallel to the length of the flutes, to thereby reduce the thickness of the fluted ply A in the first attenuated zones from that in non-attenuated zones, where each bonded zone being mainly located within a first attenuated zone.
