Industrial-grade transparent polyester film tape with aggressive acrylic adhesive for splicing and web processing. Quick stick, permanent hold, temperature resistant -60°F to 300°F. 1.5 inch width, 72 yard length, 24 rolls per case.
3M™ Polyester Film Tape 850 is a premium industrial adhesive tape engineered for demanding splicing and web processing applications. This transparent polyester film tape features an aggressive acrylic adhesive that provides quick stick and excellent long-term holding power, making it ideal for butt splices and permanent bonding requirements. The thin, high-strength polyester backing meets low caliper requirements to ensure it won't interfere with most machinery processes while maintaining superior abrasion resistance and tear protection during rough handling and web processing operations.
The tape delivers exceptional performance across a wide temperature range from -60°F (-50°C) to 300°F (150°C), making it suitable for both high and low temperature industrial environments. With a tensile strength of 28 lb/in and 120% elongation at break, this tape provides reliable performance in critical applications. The transparent formulation is particularly valued for label protection applications where readability is essential, and it meets various aerospace specifications for specialized applications. Each case contains 24 rolls of 72-yard length tape, providing ample supply for continuous production operations.
This industrial-grade tape is designed specifically for professional and occupational use in manufacturing, automotive, construction, electronics, and food processing industries. The pressure-sensitive acrylic adhesive grabs on contact and holds securely, eliminating the need for additional fastening methods. The polyester backing resists tearing and protects surfaces from abrasion while the chemical and solvent-resistant properties of the transparent version make it suitable for challenging industrial environments.
