| 摘要 |
The present invention relates to an adhesive tape which is low in cost and the properties of which such as unwindability, adhesiveness, trimmed clearance, printability, transparency and longitudinal tearing strength are improved without spoiling lateral hand cutting characteristics, wherein a smooth surface is formed on one side of a polyolefin resin base film and an uneven surface is formed on the other side thereof, the latter being coated with an adhesive and having an uneven depth of 0.03-0.30 mm and an uneven interval of 0.5-5.0 mm, the melt index of polyolefin resin being 0.2-20 g/10 min. and a surface wetting tension of the smooth surface of the polyolefin resin base film being less than 30 Dyn/cm and that of the uneven surface being more than 35 Dyn/cm.
