Teflon™ Coatings Serve High-Heat Packaging with High Performance

Teflon™ Coatings Serve High-Heat Packaging with High Performance

Dec 4th 2019

The flawless, repeatable release properties of Teflon™ coatings make them ideal for a number of applications on packaging lines. Teflon™ coatings consistently convey goods and packaging materials, seal plastic bags, and line glue pots, among many other functions. These coatings cover the high-temperature bars that seal plastic packages, as well as the glue pots that dispense glue for sealing.

Popular Teflon™ Systems for Packaging

The 3-Coat Reinforced System (857G-040/-140/-240) is the preferred Teflon™ coating for packaging because of its high temperature rating, nonstick properties, and industry-leading durability. Other applications on packaging lines use FEP Teflon™ S One Coats, and pure FEP and PFA topcoats.

The 3-Coat Improved Standard is the premium Teflon™ coating line reinforced for scratch and durability. The line is for end-uses that require non-stick, thermal stability to 500° F, and high lubricity. Decades of innovation and technology have led to significant improvements in this coating. This water-based, multi-color system is a unique blend of PTFE, PFA, and FEP fluoropolymer chemistry. The three coats are Primer (855G-021), Midcoat (857G-135 or -130), and Topcoat (857G-240).

These coatings are available in FDA-Compliant versions. It’s always a good reminder to note that that there are 21 FDA-compliant Teflon™ coating systems. According to the FDA website: “It is the responsibility of the manufacturer of a Food Contact Substance (FCS) to ensure that food contact materials comply with the specifications and limitations in all applicable authorizations.” In the simplest terms, FDA compliance means that any material that might contact food is inert and safe for human consumption.
