Multilayered material sheet and process for its preparation

A multilayered material sheet comprising:

• a consolidated stack of unidirectional monolayers of drawn polymer, said unidirectional monolayers of drawn polymer having a melting temperature, the consolidation of said stack being carried out at a temperature below the melting temperature of the drawn polymer monolayer, wherein
• the draw direction of two subsequent monolayers in the stack differs, and wherein
• at least one monolayer comprises more than one unidirectional tape of the drawn polymer, each tape comprising 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, and wherein adjacent tapes of the monolayer do not overlap.
