3M (MMM3775-3M) Printed Message Box Sealing Tape 3775 is a medium-duty industrial packaging tape engineered for secure carton closure and clear communication. It features a durable biaxially oriented polypropylene backing paired with a pressure-sensitive synthetic rubber adhesive that delivers consistent, reliable adhesion to corrugated box materials, including recycled fiberboard. The tape is pre-printed with a bold red “MIXED MERCHANDISE ENCLOSED” message on a white background, making it ideal for shipment identification and handling visibility. Designed for general industrial packaging operations, it offers excellent resistance to abrasion, moisture, chemicals, and scuffing, and unwinds smoothly for manual or automated application. Its balanced construction provides high edge tear and split resistance, helping ensure consistent performance on moderate-weight box sealing tasks. MMM3775-3M meets applicable industrial packaging standards and supports efficient workflow in distribution, fulfillment, and logistics environments.
