Technical Data Sheet

tesa® 4591 is a general-purpose bidirectional filament tape reinforced with glass filaments laminated to a polyester (PET) film backing and coated with a synthetic rubber adhesive. Designed for industrial bundling, palletizing, and securing applications, it combines high longitudinal tensile strength with minimal elongation for reliable holding power. The synthetic rubber adhesive provides strong adhesion to a variety of substrates, including low-surface-energy materials such as polyethylene (PE) and polypropylene (PP). Featuring high initial tack, fast bond build-up, and excellent adhesion to corrugated and solid board surfaces, tesa® 4591 also offers outstanding tear resistance for reliable packaging and fastening applications.

Used for a range of industrial purposes, including:
Bundling and palletizing
Heavy-duty carton sealing
Transport securing
Fixing
End-tabbing
