Industrial-grade black polyester film tape with aggressive acrylic adhesive for splicing, web processing, and marking applications. Quick-stick formula with excellent long-term holding power, temperature resistant from -60°F to 300°F. 48 rolls per case.
3M™ Polyester Film Tape 850 in Black is a premium industrial-grade adhesive tape designed for demanding splicing and web processing applications. This high-performance tape features an aggressive acrylic adhesive that provides quick stick and excellent long-term holding capabilities, making it ideal for applications requiring permanent, secure bonds. The tape comes in a convenient 3/4 inch width, 72 yard length format with a case containing 48 rolls, providing substantial inventory for continuous production operations.
The backing material is a thin, high-strength polyester film that meets low caliper requirements, ensuring it won't interfere with most machinery processes. This design feature is critical for modern manufacturing environments where tape thickness must be minimized to prevent equipment disruptions. The polyester backing resists tearing and provides exceptional protection against abrasion and rough handling during web processing, core starting, and splicing operations. The tape maintains its integrity across a wide temperature range from -60°F to 300°F, making it suitable for both cold storage and high-temperature industrial environments.
The 1.9 mil thickness combined with the pressure-sensitive acrylic adhesive creates a reliable solution for core starting, splicing and web defect marking, sealing, labeling, protecting, decorative edging, and tape hinge applications. This versatile tape meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications, ensuring compliance with industry standards. Its tensile strength of 28 lb/in provides excellent holding power, while the 120% elongation at break offers flexibility for various substrate types.
