A bi-directional tape is reinforced with continuous glass yarns in both the longitudinal and transverse direction along with a biaxially oriented polypropylene backing. The multi-level synthetic-rubber adhesive prevents delamination of fiberglass from backing. Brands, bar codes and other graphics can be read through the translucent tape. It is specifically formulated to provide good adhesion to a wide variety of surfaces, including metal, plastic and fiberboard. This tape is an ideal choice for high-strength box reinforcing, heavy-duty sealing, shipping, splicing and palletizing.
