Box Lock packaging tape. Sticks instantly to any box. Features the power of extreme grip to ensure boxes stay securely sealed, even during rough handling. Advanced adhesive creates a secure seal over box edges. Thickness and durability reduces splitting and tearing, and makes it easier to find the start of the roll. This tape can be used to seal any type of box, including harder-to-stick to 100% recycled boxes. Guaranteed to stay sealed - if box does not stay sealed, 3M will refund the purchase price of the tape (proof of purchase required). No slivering, splitting, or tearing. Smooth unwind and quiet release. No need for layers of tape for a secure seal, one strip and it ships. Strong, durable, solvent-free hot melt adhesive seals and protects. Includes a refillable dispenser that delivers a clean cut, and fall-back tabs to help ensure the tape does not fall back on the roll.
