Abstract

Improvements introduced into a thermoplastic film laminate material comprising at least two layers of reinforced thermoplastic film bonded together, with a first outer surface of the laminate spaced substantially parallel, ribs integral with the surface of the laminate, ribs extending diagonally across the surface; the opposite outer surface of the laminate having substantially parallel, spaced, and integral sharp ribs with the opposite surface, the ribs extending diagonally across the surface in a direction diagonally opposite that of the ribs of the first surface, resulting in that the ribs on the surfaces intersect at a plurality of points, producing a network of crossed ribs.
