Our Scotch Heavy Duty Shipping Packaging Tape holds strong on all box types, including 100% recycled boxes. It's even guaranteed to stay sealed. The strong, tough, solvent-free hot melt adhesive locks in your heavy duty contents and locks out everything else. This tape resists splitting and tearing and the included dispenser includes fall-back tabs to help ensure the tape doesn't fall back on the roll. You don’t need layers of tape to get the job done-just one strip at a time-so you save time. Your heavy packages can bear the weight and stay sealed through it all with Scotch Heavy Duty packaging tape.
