Commercial-grade packaging tape is ideal for general-purpose packaging applications. Aggressive, hot-melt rubber resin adhesive bonds firmly and resists slippage. The strong bond on surfaces and strong tape backing are designed to keep your box seams closed. Backing conforms around edges and rough areas for a tight seal. Tape resists nicks, abrasions, moisture and scuffing for long-lasting hold. It also resists edge tears and splits to help keep contents secure. Tape has a 3" core and meets U.S. Postal regulations.
