Abstract
Abstract A grip tape for wrapping the gripping handle of a tennis racket, a badminton racket, a golf club, or the like which includes a porous flexible sheet with numerous thin holes provided by coating a polyurethane on a nonwoven fabric so as to provide the user with various effects such as a smooth touch feeling, shock-abosrbing, and anti-moisture effects because of the moderate flexibility and elasticity that it has. The grip tape further includes a number of projections in a desired pattern formed by applying a synthetic resin elastic layer on the upper surface, and by applying an elastic foam-expanded layer on the rear surface, so as to make possible its easy handling and increased non-slip and shock-absorbing effects, by which the grip gets to the user's hand with the most comfortable touch feeling.
