Abstract: The invention relates to a process for the production of a non-fibrous drawn polymer tape, said process comprising the steps: a) compacting a polymer powder in a press to form a compacted polymer bed; b) calendering said compacted polymer bed to form an oriented polymer tape; and c) drawing said oriented polymer tape to form a highly oriented polymer tape; characterized in that step a) comprises compacting the polymer powder at a temperature and pressure such that from 0.1 to 20 wt. % of the polymer powder as measured by DSC is melted. The invention also relates to a tape obtainable by the above process, and a monolayer, multilayered material sheet and ballistic resistant article comprising such a tape.
