Yes. The 3M 3779 tape features a standard 3-inch core that is compatible with virtually all industrial carton sealing tape dispensers, including handheld and packing line mounted models. No equipment modifications required.
The tape is printed with red diagonal lines that remain hidden on the initial carton seal. If someone attempts to remove and reseal the carton, the red lines become visible on the newly exposed tape, providing instant visual proof of tampering that is difficult to fake or ignore.
The hot melt synthetic rubber resin adhesive maintains strong adhesion down to -10°F, making it suitable for frozen food and cold chain applications. However, for extreme sub-zero storage, we recommend testing on your specific packaging substrate first.
At typical packing line speeds of 60-80 cartons per minute with 2" wide tape, one 110-yard roll provides approximately 330 linear feet of sealing. Most supervisors report that a single case of 6 rolls covers 1,800-2,000 cartons depending on carton dimensions and line speed.
