Un laminado que comprende: un cuerpo fabricado por capas apiladas múltiples de una cinta unidireccional, estando la cinta formada por una pluralidad de hilos de multi-filamento hilados de gel de polietileno de peso molecular ultra-elevado, en el que el laminado contiene no más de un cinco por ciento de resina en peso; y en el que al menos dos capas adyacentes de las capas apiladas múltiples están fundidas directamente de manera conjunta sin ninguna resina entre ellas. Disclosed are laminates from multiple stacked plies of a uni-directional tape in which the tape formed from a plurality of ultra-high molecular weight polyethylene gel spun, multi-filament yarns. The resultant laminate contains not more than five percent resin by weight. Related methods of making a laminate of this type are also disclosed.
