Product Description

3M™ Scotch® Bi-Directional Filament Tape 8959 is a specialty packaging tape reinforced with continuous glass yarns in both the longitudinal and transverse directions. This bi-directional reinforcement, combined with a biaxially oriented polypropylene backing, provides excellent abrasion, moisture, and scuff resistance. The pressure-sensitive synthetic rubber-resin adhesive ensures strong adhesion to a wide variety of surfaces, including metallic, plastic, and fiberboard.


Key Features

  • High Cross-Directional Tensile Strength: Provides excellent cut and tear resistance in both machine and cross directions, making it ideal for heavy-duty applications.

  • Transparency: Allows printing and illustrations to be visible through the tape, facilitating easy identification and branding.

  • Excellent Shear and Initial Adhesion: Ensures immediate holding power and long-term performance, reducing the need for additional reinforcement.

  • Durability: Offers excellent aging properties, maintaining box closure over extended periods and under various environmental conditions.

  • Enhanced Package Life: Protects filaments and adhesive from abrasion and moisture, extending the functional life of packages.

  • Resistance to Splitting: Prevents center seam splitting in both machine and cross directions, enhancing tape performance in demanding applications.

  • Ease of Application: Requires minimal rubdown and does not need water activation, streamlining the sealing process.


Recommended Applications

  • Heavy-Duty Box Sealing: Securing heavy packages that require reinforced sealing to prevent opening during transit.

  • Cross Web Splicing: Joining materials in both machine and cross directions, ensuring structural integrity.

  • Reinforcing: Strengthening packages or materials that are prone to tearing or splitting.

  • Pallet Unitizing: Securing multiple packages on a pallet to prevent shifting during transportation.
