Abstract

PURPOSE:To impart an appropriate pliability to a tape and prevent collapsing or slipping-off of luggage by a method wherein a crude tape material is thermally stretched while restricting the shrinkage in the width direction thereof to restrain the orientation of molecules. CONSTITUTION:Polyethylene extruded through a die 2 or a crude tape material a consisting mainly of the polyethylene extrudate is passed sequentially through cooling rollers 3, 3, the first take-up roll 4, a smooth surface 6a of a hot plate 6 and the second take-up roll 5 and is fitted on a winder 8. The tape material a is thermally stretched by the difference between the revolution numbers of the first and second take-up rolls 4 and 5, while moving it in contact with the surface 6a of the plate 6. Since the crude tape material a is moved making contact with the surface 6a of the hot plate 6, the shrinkage in the width direction thereof is restricted by the friction between the material a and the surface 6a, so that the material is formed into an extra thin resin tape while being stretched in that condition.
