Duct Tape 3M 309B5066

3M 309B5066 duct tape is a brown, biaxially oriented polypropylene (BOPP) tape designed for general-purpose bundling and light sealing tasks. With a length of 66 m, width of 50 mm and a film thickness of 0.05 mm, this tape provides a balance of conformability and tensile strength appropriate for indoor and outdoor use. The adhesive backing adheres to a range of common surfaces, offering temporary holding and protective functions in packaging, maintenance and repair tasks.

Advantages

The BOPP film construction gives the tape dimensional stability and resistance to stretching, while the pressure-sensitive adhesive provides immediate tack and consistent adhesion to cardboard, plastics and many painted surfaces. Its thin profile allows neat wrapping and reduces bulk on joints and bundles. The brown color aids discrete appearance on corrugated boxes and certain packaging applications. Materials and adhesive formulation are selected for reliable short- to medium-term performance across varied environments.

Suitable for

• Sealing and reinforcing corrugated boxes and cartons
• Bundling cables, pipes or small components
• Temporary fixes and light maintenance tasks
• Marking or color-coding in storage and logistics
• General-purpose household and workshop use

Key specifications

• Material: Biaxially Oriented Polypropylene (BOPP) film
• Adhesive type: pressure-sensitive adhesive
• Length: 66 m
• Width: 50 mm
• Thickness (film): 0.05 mm
• Color: brown
• Suitable for indoor and outdoor use: yes (short- to medium-term exposure)

How to use

Ensure the surface is clean, dry and free of dust, oil or loose particles before application. Unroll the required length and apply with moderate pressure to establish contact between the adhesive and substrate. For sealing boxes, align the tape along the seam and press firmly along the entire length to create a continuous bond. For bundling, wrap the tape with even tension and overlap the starting end to secure. Cut or tear the tape by hand or with a dispenser suitable for 50 mm rolls.

Usage recommendations

For optimal adhesion, apply at temperatures above 10°C and avoid prolonged exposure to direct sunlight or extreme moisture when used outdoors. Test adhesion on critical or delicate surfaces before extended use. Store rolls in a cool, dry place away from direct heat to maintain adhesive performance.
