Box Lock Shipping Packaging Tape Refill Rolls – Extreme Grip, 3-Pack with 3" Core

The Scotch® Box Lock Tape Refill Roll 3950-3 is a heavy-duty packaging tape engineered for secure, professional-grade box sealing. Featuring an advanced solvent-free hot melt adhesive, it sticks instantly to any box surface—including harder-to-stick 100% recycled cardboard—and delivers extreme grip that keeps boxes sealed even through rough handling. Its thicker, durable construction reduces splitting and tearing, while the smooth, quiet unwind and easy-to-find roll start make every application fast and clean. This 3-pack of refill rolls fits standard 3-inch core dispensers, providing 163.8 yards of total sealing power for shipping, mailing, moving, and storage applications.
