Heavy-duty packaging tape is ideal for box sealing, splicing, and other demanding packaging applications. The strong adhesive and tape backing are designed to keep box seams closed during rough handling. Hot melt adhesive seals out moisture, dust, and dirt while resisting splitting. This tape can be used as a refill for the 3M Scotch DP300-RD Hand Dispenser, H-180 Dispenser, or ST-181 Pistol Grip Dispenser. It meets U.S. Postal Service regulations and courier regulations for standard packages.
