description An unconsolidated impact and penetration resistant laminate comprises a plurality of cross-plied sheets, each cross-plied sheet further comprising (i) first and second layers of fibrous or non-fibrous ultra-high molecular weight polyethylene and (ii) first and second layers of thermoplastic adhesive, each adhesive layer having a basis weight of no greater than 5 gsm, wherein (a) the layers of polyethylene and thermoplastic adhesive alternate within the sheet, (b) at least 50 percent of the polyethylene layers are arranged such that the orientation of the first polyethylene layer is offset with respect to the orientation of the second polyethylene layer, and (c) the plurality of cross-plied sheets form a stack that, when subjected to compaction at a pressure of 255 bar and a temperature of 132 degrees C., will not suffer a pressure loss greater than 8 bar within the first two minutes as measured by Test Method B.
