Professional-grade transparent polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and aerospace applications. Quick-stick, high-strength formula with superior temperature resistance and chemical compatibility.
3M™ Polyester Film Tape 850 is a professional-grade industrial adhesive tape designed for demanding splicing and web processing applications. Featuring an aggressive acrylic adhesive that provides quick stick and excellent long-term holding power, this tape is engineered to meet the rigorous requirements of modern manufacturing environments. The transparent polyester backing combines high strength with low thickness, ensuring it won't interfere with machinery processes while providing superior abrasion resistance and protection against rough handling.
This industrial tape is ideal for a wide variety of applications including web processing, label protection, core starting, sealing, and marking operations. The transparent formulation is particularly valued for applications where readability is critical and chemical resistance is required. With tensile strength of 28 lb/in and an elongation at break of 120%, the tape delivers reliable performance across diverse industrial settings. The polyester backing resists tearing and protects surfaces from abrasion, making it an excellent choice for applications requiring durability and consistent performance.
The tape operates effectively across an impressive temperature range from -60°F (-50°C) to 300°F (150°C), making it suitable for both cold storage and high-temperature industrial processes. Meeting ASTM specifications D3330, D3652, and D3759, this tape is certified for aerospace applications and meets stringent industry standards. Available in a convenient 48-inch width by 72-yard length format with 1.9 mil thickness, each roll comes as a single unit per case, making it practical for bulk industrial operations.
