Abstract:
1. A flexible laminate comprising: a ply A comprising a uniaxially oriented or unbalanced biaxially oriented, mono-layered or multi-layered film including a waved flute configuration having a wavelength (λ) of no more than 1.5 mm and a ply A molecular orientation having a direction substantially parallel to a flute direction as determined by a shrinkage test, where each of the layers comprises a ply A flexible thermoplastic polymeric material, where the ply A flexible thermoplastic polymeric material is orientable at ambient temperature, a ply B comprising a uniaxially oriented or unbalanced biaxially oriented, mono-layered or multi-layered film including a non-fluted configuration and a ply B molecular orientation, where each of the layers comprises a ply B flexible thermoplastic polymeric material and where a direction of the ply B molecular orientation forms an angle with the direction of the ply A molecular orientation, where the ply B flexible thermoplastic polymeric material is orientable at ambient temperature, and adhesive bonds comprising bonding zones between some crests on the first side of the ply A and corresponding crest contact regions on the first side of the ply B either through co-extruded bonding layers on the first side of the ply A and the first side of the ply B or through a separately extruded lamination layer, where a thickness of the ply A within each bonding zone is substantially equal to a thickness of the ply A within adjacent un-bonded regions of the flutes or the ply A includes first solid-state attenuated zones extending parallel to the flute direction and where each bonding zone is substantially located within a first solid-state attenuated zone.
