Premium transparent 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, temperature resistant from -60°F to 300°F.
The 3M™ Polyester Film Tape 850 is a premium industrial-grade 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 permanent bonding tasks. The thin, high-strength polyester backing offers superior abrasion resistance while meeting low caliper requirements to ensure compatibility with most machinery processes without interference.
This versatile tape is engineered to withstand extreme temperature conditions, operating reliably from -60°F (-50°C) to 300°F (150°C), making it suitable for high-temperature industrial operations. The polyester backing resists tearing and protects surfaces from abrasion and rough handling, ensuring reliable performance in challenging manufacturing environments. Available in a 1-inch width by 72-yard length with 1.9 mil thickness, each case contains 36 rolls providing substantial coverage for large-scale industrial applications.
The transparent version is particularly valued for applications requiring chemical and solvent resistance, including label protection where readability is critical and aerospace applications meeting various industry specifications. With its pressure-sensitive acrylic adhesive that grabs on contact and holds securely, this tape is the preferred choice for web processing, label protection, marking, and core starting applications in diverse industrial sectors including automotive, electronics, packaging, and manufacturing.
