PURPOSE: To obtain a pressure-sensitive adhesive tape which can be cut easily and manually in the weft direction to give a unifuzzy cut surface by using flat yarns made by stretching a composition containing a polyolefin synthetic resin and a polystyrene synthetic resin as the warp.

CONSTITUTION: This tape used for packaging or curing is made by laminating a synthetic resin layer on base cloth in which the warp is flat yarn made by stretching a resin composition containing 100 pts.wt. polyolefin synthetic resin and 3-20 pts.wt. polystyrene resin and the weft is flat yarn made of a polyolefin synthetic resin and forming a pressure-sensitive adhesive layer on this surface. It is desirable for practical purpose that the warp flat yarn has a fineness of 100-800d, a tenacity of 4.5-6g/d and an elongation of 10-18%, and even when the fineness is relatively high, a tape having good manual cuttability and giving a fine cut surface can be obtained. It is desirable that the weft has a fineness one to three times as high as that of the warp.
