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.
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.
