Premium industrial polyester film tape with aggressive acrylic adhesive for splicing, web processing, and label protection. Quick-stick formula, temperature resistant -60°F to 300°F, meets aerospace specifications.
3M™ Polyester Film Tape 850 is a premium industrial adhesive tape designed for splicing applications requiring quick stick and aggressive permanent hold. This high-performance tape features a thin, high-strength polyester backing that resists tearing and protects surfaces from abrasion and rough handling during web processing. The aggressive acrylic adhesive grabs on contact and holds butt splices securely, making it ideal for demanding industrial environments. The tape meets low-caliper requirements to ensure it won't interfere with most machinery processes, and it's available in white, transparent, and silver versions to meet various application needs.
The 3M Polyester Film Tape 850 offers exceptional temperature resistance, performing reliably in high-temperature operations with a wide operating range from -60°F/-50°C to 300°F/150°C. With dimensions of 2 inches wide by 72 yards long and a thickness of 1.9 mil (0.05mm), this tape is engineered for precision applications in web processing, label protection, and marking operations. Each case contains 24 rolls, providing bulk availability for production environments. The polyester backing resists chemical and solvent intrusion, making it suitable for aerospace specifications and specialized industrial applications where reliability is critical.
This industrial-grade tape is specifically formulated for applications including core starting, splicing and web defect marking, sealing, labeling and protecting, decorative edging, and tape hinge applications. The transparent version meets aerospace industry specifications and provides excellent readability for label protection, while the silver version offers reflective sensing capabilities for defect flagging. Engineered to meet ASTM D3330, ASTM D3652, and ASTM D3759 specifications, the 3M Polyester Film Tape 850 delivers consistent performance across appliance, automotive, construction, electronics, food and beverage, metalworking, military, packaging, paper, print, and transportation industries.
