3M Brown 3739 Packing Tape, 66 m x 50 mm

This packing tape is a brown, long-length sealing solution designed for industrial and manufacturing environments where consistent adhesion and tensile performance are required. It uses a rubber resin adhesive on a biaxially oriented polypropylene backing to secure cartons and components in automation, electrical and mechanical workflows while offering a balance of stretch and strength for repetitive sealing tasks.

• 4.4N/cm adhesion strength for secure surface bonding
• 47N/cm tensile strength resists breakage under load
• 165% elongation mitigates stress during handling
• 0.054mm thickness provides Durable tear resistance
• 66m roll length reduces downtime from frequent changes
• 50mm width covers standard carton flaps efficiently

• Suitable for sealing heavy-duty cartons in assembly lines
• Ideal for bundling cable looms prior to installation
• Used with automated taping dispensers for high-volume runs
• Can be used for securing components during transit
• Suitable for electrical panel packaging and protection

The rubber resin adhesive offers firm initial tack and good adhesion to corrugated board, paper and many plastics commonly used in packaging.

The biaxially oriented polypropylene backing delivers controlled stretch and dimensional stability, helping maintain a tight seal when cartons flex.

With 165% elongation at break, the tape can accommodate sudden strain without snapping, absorbing shocks that occur in handling and transport.

The combination of tensile strength and backing properties supports high-speed dispensing and automated sealing operations without frequent breakage.

The tape meets the requirements of AFERA 5006:2008, indicating conformity with recognised European test criteria for packing tapes.
