Estimated reading time: < 1 min

A yarn which comprises a tape with a large width-to-thickness ratio, and which has an apparent width not exceeding an agreed limit (e.g., 5mm or 8mm).

Note: Such yarns are usually of paper or are formed by slitting a wide film of (usually) polyethylene or polypropylene polymer into individual tapes, with hot-stretching either before or after slitting to induce high longitudinal strength. The draw ratio in hot-stretching is kept low enough to avoid excessive longitudinal fibrillation. The tape yarn so produced is suitable for weaving.
