<p>PURPOSE: A multi-layer adhesive tape is provided to improve workability according to low frictional force, and surface protection ability at the same time by having a film layer, which has low frictional force, and another film layer, which has high frictional force. CONSTITUTION: A multi-layer adhesive tape comprise: a first film(120), in which an adhesive(110) is spread on one side, comprising polymers selected from a group consisting of polyethylene, polyvinylchloride, ethylene vinyl acetate, and polyurethane; and a second film(130), which is laminated on the other side of the first film, comprising polymers selected from a group consisting of oriented polypropylene, high density polyethylene, polypropylene, and polyethylene terephthalate. The frictional coefficient of the first film is higher than the frictional force of the second film.</p> |
