SUPPORT FOR ADHESIVE TAPE AND ADHESIVE TAPE

PROBLEM TO BE SOLVED: To provide an adhesive tape which has improved unwinding workability and ensures hand tearing property with fine dimensional accuracy. SOLUTION: This support 10 for an adhesive tape is obtained by approximately continuously alternately forming the first grooves 12 having a depth of 0.01 to 0.03 mm, respectively, over the whole width of a plastic tape-like article 11 preferably comprising a polyolefin resin such as polyethylene or polyproprylene and the second grooves 13 having a depth of 0.03 to 0.09 mm, respectively, over the width of the tape-like article at a distance of 0.10 to 0.50 mm on one side of the tape-like article in the longitudinal direction of the tape-like article. An adhesive layer 20 comprising an adhesive such as an acrylic resin-based adhesive or a rubber-based adhesive is preferably laminated to the groove 12, 13-non-formed side of the support 10 for the adhesive tape to obtain the adhesive tape 1.
