Professional polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and sealing applications. Temperature resistant from -60°F to 300°F with 72 rolls per case.
3M™ Polyester Film Tape 850 is a professional-grade industrial adhesive tape specifically engineered for splicing and web processing applications. This transparent tape features an aggressive acrylic adhesive that provides quick stick and excellent long-term holding power, making it ideal for 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.
Designed for a wide range of industrial applications including web processing, label protection, marking, core starting, and sealing, this tape delivers reliable performance across multiple industries. The polyester backing is engineered to withstand extreme temperature ranges from -60°F (-50°C) to 300°F (150°C), making it suitable for both high-temperature operations and cold environments. The transparent version is particularly valued for applications where readability is critical and for aerospace industry specifications.
Each case contains 72 rolls of 1/2 inch width by 72 yards length tape with a 1.9 mil thickness. The tape meets rigorous ASTM specifications (ASTM D3330, ASTM D3652, ASTM D3759) and is chemical and solvent resistant, providing superior protection in challenging industrial conditions. For industrial and occupational use only, this tape is engineered to deliver consistent, reliable performance in manufacturing, packaging, electronics, automotive, and aerospace applications.
