Claim:
1. A multilayered material sheet comprising a consolidated stack of unidirectional monolayers of drawn polymer, wherein two subsequent monolayers in the stack have draw directions which differ from one another, and wherein at least one monolayer comprises at least one unidirectional tape of the drawn polymer, each tape comprises longitudinal edges, wherein the monolayer is free of an area of elevated thickness adjacent to and along the substantial length of the longitudinal edges of the at least one unidirectional tape, wherein the monolayer contains more than one unidirectional tape of the drawn polymer whereby adjacent tapes do not overlap, and a binder, wherein the binder comprises less than 20% of the weight of the monolayer or a consolidated stack comprising the monolayer.
