A support tape extends longitudinally along an elongated object, is wrapped around the object, and has a pair of opposite longitudinal edges, an inner face engaging the object, and an outer face turned outward away from the object. The support tape is of single-layer design and having a class D abrasion resistance according to LV 312-1. One closure strip of an adhesive compound extends along one of the faces at one of the edges, and another closure strip of an adhesive compound extends parallel to the edges, along the other face, and transversely offset on the other face from the one closure strip. It is adhered to the one closure strip. A fixing strip of an adhesive compound extends longitudinally on the inner face, offset thereon from the one and other closure strips, and adheres the tape to the object.

Disclosed are a method of preparing an elastic pressure-sensitive adhesive tape and an elastic pressure-sensitive adhesive tape. Main components of the adhesive include a polyacrylate resin with a carbon-carbon double bond and a diluent monomer with a carbon-carbon double bond. A quasi-microcapsule powder component is adopted, wherein the shell material of the quasi-microcapsule powder selects a cellulose-based water soluble polymer, and the core material selects low boiling point alkane, wherein the preparation method combines UV curing, heating, and shell burst, to obtain an elastic adhesive layer, whereby to prepare a pressure-sensitive adhesive tape product. Compared with conventional elastic pressure-sensitive adhesive tapes, the preparing method as disclosed has a simple manufacturing process. The pressure-sensitive adhesive tape obtained from the disclosed preparing method overcomes the restrictions of conventional foam strips and provide good cushioning and compression properties without using foam as the carrier.
