Professional-grade polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and high-temperature applications. Quick-stick formula with excellent long-term holding power.
3M™ Polyester Film Tape 850 is a high-performance 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 for applications requiring permanent, secure bonds. The thin, high-strength polyester backing meets low caliper requirements, ensuring it won't interfere with most machinery processes while providing superior abrasion resistance and protection against rough handling. With tensile strength of 28 lb/in and elongation at break of 120%, this tape delivers exceptional durability and flexibility for demanding industrial environments.
The tape is available in a 3-inch width by 72-yard length configuration, with a total thickness of 1.9 mil (0.05mm), packaged in convenient 12-roll cases for industrial operations. Its polyester backing resists tearing and protects surfaces from abrasion and rough handling, making it ideal for web defect marking, core starting, sealing, labeling, and decorative applications. The tape operates reliably across a wide temperature range from -60°F (-50°C) to 300°F (150°C), enabling use in both cold storage and high-temperature industrial operations.
This industrial-grade tape meets multiple ASTM specifications including ASTM D3330, ASTM D3652, and ASTM D3759, ensuring compliance with industry standards. Suitable for use across diverse industries including automotive, aerospace, electronics, food and beverage, metalworking, packaging, and transportation. The transparent version offers chemical and solvent resistance for specialized applications, while colored versions provide high visibility for marking and identification purposes.
