摘要：<p>For manufacturing tape or yarns, plastic polymer material is extruded into a film (20, 21) having a pattern of parallel, longitudinal, alternating ribs (31, 32) and grooves (33, 34) on each of its two opposite sides, at least a plurality of the grooves (33, 34) in one side each being located diametrically opposite one of the grooves (34, 33) in the other, opposite side. Yarns and tapes obtained in the form of or from such a film typically have a substantially improved tenacity and are more supple and smooth. <IMAGE></p>
