High-performance packaging tape combines a strong polypropylene backing reinforced with continuous glass yarn filaments & a synthetic rubber resin adhesive. This aggressive adhesive is specifically formulated to provide an excellent balance of initial adhesion & long-term holding power to most fiberboard surfaces, including recycled & printed fiberboard surfaces. Tape is ideal choice for heavy-duty sealing, shipping & splicing. It provides very good holding power under a wide range of conditions. Tough, clear film backing is abrasion-resistant & moisture-resistant, provides good aging & protects the filaments & adhesive to help your boxes remain closed for long period of time. The backing, filaments & adhesive combine to provide high tensile & shear strength & provide an extra layer of security against tampering & product theft.
