The DuraStick® Industrial Zone Tapes utilize DuraFab® Industrial Fabrics and have an adhesive on the edges of one side. These tapes are manufactured from woven fiberglass substrates, possess an optimal PTFE (Fluon®) content, leave a minimal fabric impression, and have a proprietary adhesive system. The absence of adhesive in the center zone allows for faster heat transfer through the tape, and makes the tape an excellent choice for specific types of impulse sealing applications, such as the manufacture of plastic bags. Impulse sealing wires and ribbons are free to expand and contract without being encumbered by adhesive, helping to extend their working life. The DuraStick® Zone Tapes are a quick, easy and economical means of applying a non-stick surface to heat-sealing platens.

What Are DuraStick® Industrial Tapes?

DuraStick® PTFE Coated Zone Tapes are engineered to retain the distinctive properties of PTFE; however, by adding a glass fabric to the matrix, AFC is able to obtain the added benefits of dimensional stability, excellent tensile strength, and extremely low elongation (<1). The addition of adhesive strips on the edges eliminates the need for mechanical fastening. This proprietary adhesive system is extremely aggressive, has an unlimited shelf life, and operates over a range of temperatures from -40°F to 350°F (-40°C to 177°C); while the center, non-adhesive, zone can withstand temperatures ranging from -400°F to 550°F (-240°C to 288°C). These tapes have received USDA approval for food processing and handling, and are FDA compliant (21 CFR177.1550).
