Professional industrial polyester film tape with aggressive acrylic adhesive for splicing, web processing, and marking applications. White color, 6 inch width, 72 yard length per roll, 1.9 mil thickness. Temperature resistant -60°F to 300°F. 8 rolls per case.
3M™ Polyester Film Tape 850 is a professional-grade adhesive tape specifically designed for splicing and web processing applications in industrial environments. Featuring an aggressive acrylic adhesive that provides quick stick and excellent long-term holding power, this tape is ideal for applications requiring permanent bonds that won't fail under stress. The thin, high-strength polyester backing meets low caliper requirements, ensuring it won't interfere with most machinery processes while providing exceptional resistance to tearing and abrasion during rough handling and web processing operations.
This versatile tape is engineered to perform in demanding industrial conditions with a wide temperature operating range from -60°F to 300°F (-50°C to 150°C). The polyester backing resists tearing and protects surfaces from abrasion and rough handling, making it an excellent choice for core starting, splicing, sealing, labeling, and protective applications. Available in multiple colors including white, transparent, red, black, and silver, the tape offers high visibility options for applications where marking or identification is critical. The transparent version provides chemical and solvent resistance, making it suitable for aerospace applications and sensitive environments.
Each case contains 8 rolls of tape, with each roll measuring 6 inches wide by 72 yards long with a 1.9 mil thickness. The pressure-sensitive acrylic adhesive grabs on contact and holds butt splices securely, making it reliable for web defect marking, label protection, decorative edging, and tape hinge applications. This product meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications and is suitable for use across multiple industries including automotive, construction, electronics, food and beverage, metalworking, military, packaging, and transportation.
