Scotch Box Lock Packing Tape has the power of extreme grip to ensure boxes stay securely sealed, whether you're packing, shipping, mailing or moving. This shipping tape is thick and durable to reduce splitting and tearing and makes it easier to find the start of the roll. Designed with advanced, solvent-free adhesive, it creates a secure, instant seal over box edges and seams that holds strong even through rough handling conditions. This packaging tape features premium sticking power that works on all box types, including harder-to-stick 100% recycled boxes, and is guaranteed to stay sealed (1). Each roll unwinds quietly and easily to make application a breeze. Fall-back tabs on the tape dispenser help ensure the tape doesn’t fall back on the roll, keeping it ready for the next use. (1) If your box does not stay sealed, 3M will refund the purchase price of this tape. Proof of purchase required. Contact: 1-800-3MHELPS
