3M 7000123942 Security Message Box Sealing Tape

Product Description

The 3M 7000123942 is an industrial-grade polypropylene box sealing tape designed for medium-duty packaging applications. The transparent film backing carries a red printed message reading CHECK SEAL BEFORE ACCEPTING, giving recipients a clear tamper-evident indicator before opening. The synthetic rubber adhesive delivers strong conformability under stress and bonds reliably to recycled fiberboard, liner paper, and a wide range of medium-weight box materials. The tape resists abrasion, moisture, chemicals, and scuffing, making it suitable for demanding warehouse and distribution environments where package integrity must be verifiable on delivery.

This tape is intended for general industrial and commercial packaging operations. It performs well on high-speed automated packaging lines due to its easy unwind and smooth dispensing characteristics. Typical users include shipping and receiving departments, distribution centers, and industrial packaging operations that require a visible security message on outbound cartons. The minimum order quantity is 36 rolls per case, making it appropriate for facilities with consistent, high-volume sealing needs.

Installation Notes

Apply to clean, dry carton surfaces free of dust, oil, or moisture for best adhesion. Ensure the tape is fully seated along all seams using a tape gun or dispenser with a firm roller. When used on automated packaging lines, verify dispenser tension settings are appropriate for the roll size to prevent uneven application or tearing.
