    摘要: The invention relates to a method for producing a highly oriented, high molecular weight polymer tape. The method comprises forming and compression-moulding a polymer powder bed at a temperature below the melting point of the polymer to form a sheet; at a temperature below the melting point of the polymer, rolling and stretching the sheet in a calendar unit to form a partially oriented polymer web; at a temperature below the melting point of the polymer, drawing the partially oriented polymer web in a drawing unit; and, optionally repeating step c) to form a more fully oriented non-fibrous high molecular weight polymer tape, the method being discontinuous in that the ingoing line speed of one of the method steps b) to d) differs from the outgoing line speed of the preceding method step.The invention also relates to a device for carrying out the method.The invention further relates to a material sheet comprising the polymer tapes, and to a ballistic resistant article comprising the material sheet. A ballistic resistant article comprising the material sheet exhibits excellent antiballistic properties.
