ABSTRACT:
A tear/puncture resistant semi-laminate material having a first layer of a flexible sheet of thermoplastic material and a second layer of a water impermeable thermoplastic material impregnated with a volatile corrosion inhibitor. The layers are not bonded with a uniform layer of adhesive, but are semi-laminated by bonding at points or in strips at the edges of the respective layers or at discrete, discontinuous intervals across the width of the material. In the preferred embodiments, the first layer is a tear resistant layer, which may be a layer of woven fibers, a nonwoven layer of spunbonded fibers, or a tear resistant film. In an alternative embodiment, polypropylene is substituted for polyethylene in the first and second layers.
