Packaging tape 3M 6890 brown, 66 m length x 50 mm width

3M 6890 brown packaging tape, 66 m by 50 mm, is designed for sealing cartons and parcels in general packing and shipping operations. The tape combines a pressure-sensitive adhesive with a film backing to deliver consistent adhesion for manual and machine application. It is intended to secure boxes for storage, transport and distribution while providing a discreet brown color that blends with corrugated cardboard surfaces.

Advantages

The tape provides reliable holding power on a range of carton surfaces and offers good shear resistance during handling and transit. Its pressure-sensitive adhesive adheres immediately on application without the need for heat or primers, and the film backing resists tearing under normal packaging stresses. Suitable for both hand dispensers and automated case-sealing equipment, the tape maintains consistent unwind and laydown, reducing jams and application variation.

Suitable for

• Sealing cartons for courier and postal shipping
• Warehouse packing and pallet consolidation
• Manual taping with hand dispensers
• Machine application on case sealers and packaging lines

How to use

Ensure carton surfaces are clean, dry and free from dust or grease before application. For manual use, load the roll into a compatible hand dispenser, apply tape across the joint and press firmly to secure adhesion along the box flaps. For machine application, install the roll according to the equipment manufacturer’s instructions, verify proper tension and alignment, and run a test seal to check adhesion and laydown. Store unused rolls in a cool, dry place away from direct sunlight to preserve adhesive performance.

Usage recommendations

For optimal results on heavy or irregular surfaces, test adhesion on a sample carton and, if necessary, use additional tape layers or reinforced tape. Avoid applying tape to dusty, oily or frozen surfaces; for automated lines, confirm core and roll dimensions match equipment specifications to prevent feed issues.
