Scotch Box Sealing Tape 311 securely closes a wide variety of lighter-weight box materials, including recycled fiberboard. Specially developed polypropylene backing is easy to handle and maintain its performance and appearance better than most products when exposed to fluorescent and UV light. The backing easily conforms around edges and on rough surfaces for a tight seal. This tape works well on boxes weighing up to 70 lb. It keeps sticking even with wide temperature swings. Tests on the adhesion capabilities of this tape in wide temperature swings and moist environments proved it is suitable for colder and damper applications with easy handling and smooth dispensing. Medium-duty sealing tape with 3" core is designed to securely close regular slotted containers (RSC) and packages used for moving, shipping and distribution. The tape's durability and high hold work especially well on challenging recycled corrugate and fiberboard. Apply with portable handheld or stationary dispenser.
