Duct Tape 3M 3739T756

The 3M 3739T756 duct tape is a transparent Biaxially Oriented Polypropylene (BOPP) tape designed for indoor packaging and general sealing tasks. With a length of 66 m and a width of 75 mm, it provides a continuous, clear surface for securing cartons, bundles and wrapped items. The tape’s 0.056 mm thickness and break elongation of 160% deliver a balance of conformability and tensile strength suitable for light- to medium-duty applications where visibility of contents or labels is required.

Advantages

Transparent construction allows the underlying label or print to remain visible while providing adhesion and protection. The BOPP backing gives dimensional stability and resistance to splitting, while the specified thickness ensures a consistent unwind and reliable application with hand dispensers or automatic machines. High elongation before break helps absorb shocks during transport, reducing the likelihood of premature failure on boxes and packages.

Suitable for

• Sealing and closing corrugated cartons for shipping and storage
• Securing product bundles and preventing shifting during handling
• Wrapping and protecting printed labels or barcodes while keeping them readable
• Light assembly or temporary holding tasks in warehouses and distribution centers

Key specifications

• Intended use: Indoor packaging and sealing

How to use

Clean and dry the application surface before applying the tape to ensure optimal adhesion. Measure and cut the required length by hand or with an appropriate dispenser. Apply the tape with firm pressure along the seam or edge to create a continuous bond; for best results smooth from the center outward to remove air pockets. When using on corrugated cartons, overlap the tape slightly at the ends to improve hold and resistance to transit stresses.

Usage recommendations

Store rolls in a cool, dry place away from direct sunlight and temperatures outside the recommended indoor range to preserve adhesive performance. For heavier loads or outdoor exposure, consider a reinforced cloth tape or solvent-based tape designed for those conditions. Test adhesion on a sample surface if using on coated or delicate materials to avoid damage.
