Scotch® Box Sealing Tape 351 securely seals a wide variety of box and carton materials, including corrugated fiberboard. Knowing that cartons take a lot of rugged treatment in transit, we developed a moisture-resistant polyester backing that resists high temperatures, chemicals, scuffing and abrasion to hold securely throughout the entire shipping process. Ideal for use with hard-to-seal surfaces, high humidity environments and double or triple walled boxes This tape is recommended for heavy box sealing (weighing up to 100 lbs.) and other demanding packaging applications. A tough tape that is also environmentally friendly Scotch® Box Sealing Tape 351 features a biaxially oriented polyester backing with pressure-sensitive synthetic rubber hot melt adhesive. It features high edge tear and split resistance and complies with environmental considerations of ASTM D1974-92. Developed to help ensure that packages arrive intact Heavy duty sealing tape, also known as packing tape or adhesive tape, is designed to securely seal heavy weight or over-packed cartons and packages for shipping and handling.
