Duck® Brand Reinforced Gummed Paper Tape is made with a heavy-duty, water activated adhesive that provides an instant bond and industrial performance seal to most corrugated surfaces. To apply, simply cut to size, wet the adhesive-side of the paper with a sponge, spray bottle or rag to activate the adhesive, and then stick to the box. Or, use a gummed tape dispenser machine (sold separately). Designed for heavy-duty, high-volume or industrial shipping, the tape backing is reinforced with fiberglass filament for extra tensile strength to avoid splitting or tearing. The tape backing is also waterproof to help keep your box in tact in all weather conditions.
