This is a roll of Scotch 371 or 371+ industrial-grade box sealing tape. It is designed for medium-duty packaging applications. The tape features a high-tack synthetic rubber or rubber resin adhesive that sticks quickly to various materials, including fiberboard. The polypropylene film backing resists abrasion, moisture, and scuffing. It can be applied manually with a handheld dispenser or with automated machinery.
