Film Sticking
Packaging film can adhere to heated contact points and disturb sealing speed or finished pack quality.
Application solution
PTFE Release Liners for Packaging Machinery
Heat-resistant non-stick fabrics, fitted liners and custom converted parts for sealing jaws, guides and packaging machine contact surfaces.
Process context
Application Overview
Packaging machinery often places heated jaws, guides and sealing surfaces in repeated contact with films and adhesives.
Buyer pain points
Challenges in This Application
Adhesive Buildup
Residue on jaws and guides increases cleaning work and may contribute to unplanned machine stops.
Complex Geometry
Machine contact areas often require accurate holes, slots, folds or fitted liner shapes.
Frequent Replacement
Wear parts need repeatable specifications and practical packaging for maintenance inventory.
Recommended material system
Our Solution
Use PTFE-coated fiberglass, selected liners or fabricated parts as release surfaces shaped for the machine and sealing area.

Frequently Asked Questions
Which PTFE material is used on packaging sealing jaws?
PTFE-coated fiberglass fabrics and fabricated liners are common starting points, but the final construction depends on temperature, pressure, jaw geometry and wear.
Can liners be manufactured from a machinery drawing?
Yes. Custom parts can be converted from dimensioned drawings, CAD references or an approved physical sample.
Are adhesive-backed PTFE liners available?
Adhesive-backed constructions may be available depending on temperature, mounting surface and replacement requirements.
What should I include in a packaging machinery inquiry?
Provide the machine location, drawing, dimensions, temperature, pressure or contact conditions, current material and expected quantity.
