Premium 3-inch silver polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and marking applications. 72-yard rolls, 12 per case, temperature-rated -60°F to 300°F.
The 3M™ Polyester Film Tape 850 in Silver is a premium industrial adhesive tape specifically engineered for splicing and web processing applications. Featuring an aggressive acrylic pressure-sensitive adhesive that provides quick stick and excellent long-term holding power, this tape delivers reliable performance in demanding industrial environments. The thin, high-strength polyester backing meets low caliper requirements, ensuring it won't interfere with most machinery processes while resisting tearing and protecting surfaces from abrasion and rough handling.
This professional-grade tape is designed for applications requiring permanent, secure bonds with minimal setup time. With a width of 3 inches and a length of 72 yards per roll, each case contains 12 rolls for bulk purchasing convenience. The tape maintains performance across a wide temperature range from -60°F (-50°C) to 300°F (150°C), making it suitable for both cold and high-temperature operations. The silver color variant provides high visibility for applications where marking or identification is essential, such as defect flagging where reflective sensing is required.
Meeting multiple aerospace specifications and industry standards including ASTM D3330, ASTM D3652, and ASTM D3759, this tape is ideal for core starting, splicing and web defect marking, sealing, labeling, protecting, decorative edging, and tape hinge applications. The 1.9 mil thickness and 120% elongation at break ensure flexibility and durability. Recommended for industrial and occupational use only, this tape is not intended for consumer applications and must be used in compliance with applicable health and safety regulations.
