High-strength transparent polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and marking applications. Wide temperature range -60°F to 300°F. 2 inch x 72 yard rolls, 24 per case.
3M™ Polyester Film Tape 850 is a premium industrial adhesive tape designed for demanding 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 butt splices and temporary bonding tasks. The thin, high-strength polyester backing meets low caliper requirements to ensure it won't interfere with most machinery processes, while maintaining exceptional durability through rough handling and abrasion-prone environments.
The tape is engineered to withstand a wide temperature range from -60°F (-50°C) to 300°F (150°C), making it suitable for both cold storage and high-temperature industrial operations. With a tensile strength of 28 lb/in and 120% elongation at break, this tape delivers superior performance in web processing, label protection, marking applications, and core starting operations. The transparent version is particularly valued for applications where visibility and readability are critical, such as aerospace specifications compliance and chemical-resistant sealing.
This industrial-grade tape comes in a convenient 24 roll case format, with each roll measuring 2 inches wide by 72 yards long and 1.9 mil total thickness. The polyester backing resists tearing and protects surfaces from abrasion while the pressure-sensitive acrylic adhesive grabs instantly on contact for secure, permanent holds. Compliant with ASTM D3330, ASTM D3652, and ASTM D3759 specifications, this tape is the preferred choice for manufacturing, aerospace, automotive, and packaging industries requiring reliable splicing solutions.
