Medium-duty tape adheres instantly to both virgin & recycled fiber surfaces to generate an immediate destructive bond. Starch-based adhesive aggressively bonds to corrugated cartons, even in dusty or dirty environments. Durable construction is not affected by extreme hot or cold temperatures to allow use in all weather conditions. Water-activated formulation leaves a broken seal for tamper-evident packages. Sealing tape is designed for use on average-weight cartons up to 55 lb.
