Abstract
The present invention relates to a double-sided pressure-sensitive adhesive tape comprising a nonwoven fabric as a support; one pressure-sensitive adhesive layer disposed on one side of the support; and another pressure-sensitive adhesive layer disposed on the other side of the support, wherein the nonwoven fabric consists of Manila hemp and is impregnated with carboxymethyl cellulose. The double-sided pressure-sensitive adhesive tape according to the invention can be produced with a high productivity, does not cause shrinkage wrinkles even when prepared by direct application, and has good blanking workability owing to its small elongation and excellent strength.
