Anti-Static Roll Covers
Industrial anti static roll covers for manufacturing equipment.
Fluoron anti static roll covers are heat shrink conductive fluoropolymer covers for industrial rollers used in paper, film, converting, and electronics assembly. These are not anti static bubble wrap, foam rolls, or ESD packaging materials. Fluoron is a US manufacturer of industrial roller covers since 1990, a Spectrum Advanced company.
Anti-static roll covers from Fluoron’s Fluoro-Stat system. Carbon-reinforced PTFE heat-shrink sleeves that bleed static charge to ground while delivering the non-stick release and chemical resistance of standard PTFE. Engineered for flexible packaging, converting, solvent processing, and any line where uncontrolled static is causing product defects, fire risk, or equipment damage.
When standard PTFE is creating a static problem
Standard PTFE is an excellent insulator, which is exactly the problem when your line is generating static. Web flutter, dust attraction, ignition risk near solvent vapors, and finished product defects all come from charge that has nowhere to go. Anti-static roll covers solve it by adding controlled carbon reinforcement that gives the cover a defined surface resistivity, dissipating charge to ground while keeping the release performance you came to PTFE for.
- Your line is generating static that causes web flutter, edge curl, or dust attraction
- You are running solvent-based coatings or printing inks where ignition risk is real
- Finished product defects are tied to electrostatic discharge during converting
- You need PTFE-class release plus controlled conductivity in a single cover
- Standard tinsel bars or active static eliminators are not enough or are too maintenance-heavy

Anti-static vs static-dissipative vs conductive
The terminology around static control gets confusing fast. Here is how the three terms relate, and where Fluoro-Stat sits.
- Anti-static typically means a surface that resists building up a charge in the first place, often a coating treatment. Resistivity is usually 10^10 to 10^12 ohms per square.
- Static-dissipative means a surface that bleeds an existing charge to ground at a controlled rate, typically 10^6 to 10^9 ohms per square. This is what Fluoro-Stat delivers and what most production lines actually need.
- Conductive means a true electrical conductor, typically below 10^6 ohms per square. Useful for grounding paths but overkill for most static control needs.
Fluoro-Stat is static-dissipative. We refer to it as anti-static because that is the search term most engineering and production teams use when looking for the solution to their problem. Functionally, what you need on a converting line, a film processing line, or a solvent-handling line is a cover that drains charge fast enough to prevent the problem, without becoming a true conductor that creates new ground-path issues.
Where anti-static roll covers fit best
- Flexible packaging converting lines where film static causes web flutter or layup defects
- Solvent-based printing and coating where electrostatic discharge near flammable vapors is a fire risk
- Dust-sensitive processing lines where static-attracted contamination is a quality problem
- Electronic and circuit film handling where ESD damage to product is a real cost
- Dry solvent process lines in pharmaceutical, food, or specialty chemical manufacturing
Frequently asked
What is an anti-static roll cover?
An anti-static roll cover is a heat-shrink tube of carbon-reinforced PTFE that slides over an existing roll body and shrinks tight to the substrate when heat is applied. The carbon loading gives the surface a defined static-dissipative resistivity, bleeding charge to ground at a controlled rate while preserving PTFE-class non-stick release and chemical resistance.
How does an anti-static roll cover compare to tinsel bars and active static eliminators?
Tinsel bars and active eliminators are point-source devices that handle static at one location on the line. An anti-static roll cover handles charge at the roller surface itself, continuously, with no moving parts and no maintenance. For continuous low to moderate charge generation, Fluoro-Stat often replaces multiple tinsel stations. For high-velocity webs and heavy static loads, customers pair Fluoro-Stat with one upstream active eliminator instead of a network of tinsel bars.
Are anti-static roll covers food contact compliant?
No. The carbon reinforcement that makes Fluoro-Stat work also disqualifies it for direct food contact under 21 CFR 177.1550. For food contact applications, use Fluoro-Wear PTFE (opaque white) or Fluoro-Clear FEP (translucent), both of which are FDA compliant.
Can anti-static roll covers be installed onsite?
Yes. We mobilize installation crews to customer sites for large-diameter rolls, in-place assets, and converting lines that cannot easily be torn down. Tell us the roll location and accessibility and we will quote shop versus onsite.
How long do anti-static roll covers last in service?
Service life depends on web abrasion, temperature, and chemistry. Typical Fluoro-Stat installations on flexible packaging converting lines run 18 to 48 months between replacements. The carbon reinforcement does not measurably reduce wear life vs standard PTFE. We track each installation to inform future specs.
