PTFE Adhesive Tapes for Heat Sealing and Non-Stick Industrial Surfaces
PTFE adhesive tapes provide a durable non‑stick, low‑friction surface for heat seal jaws, guides, chutes, and wear points on packaging and processing equipment across New Zealand. Brown International supplies PTFE glass cloth and skived PTFE film tapes from leading global manufacturers, with local technical support and custom slitting to suit your machinery.
Key features
Non‑stick PTFE surface to prevent product build‑up and sticking on heat seal jaws, guides, and chutes.
High temperature resistance for continuous service in demanding sealing and conveying environments.
Excellent chemical resistance to oils, acids, solvents, and cleaning agents used in production lines.
Good dimensional stability and tensile strength, especially in PTFE glass cloth constructions for higher mechanical loads.
Electrical insulation properties for use in coil wrapping, composite processing, and masking in electronics manufacturing.
Typical applications
Heat seal jaw covers on flow wrappers, L‑bar sealers, vacuum sealers, and form‑fill‑seal machines.
Non‑stick liners and wear strips on guides, chutes, and transfer plates in packaging and plastics processing.
Release surfaces on heat platens and sealing bars to prevent sticking of films and laminates.
Electrical insulation and low‑friction wraps in electronics, composite bonding, and general industrial equipment.
Available constructions and formats
PTFE glass cloth tapes for high‑strength, wear‑resistant non‑stick surfaces on jaws and guides.
Skived PTFE film tapes for smoother, more conformable low‑friction surfaces in lighter‑duty applications.
Silicone and acrylic adhesive systems to suit different substrates and operating conditions.
Options supplied with or without liners to match manual or automated application processes.
Custom slit rolls to your required widths for specific seal bar lengths and machine setups.
How to specify PTFE tape
When you contact us, it helps to confirm:
Application (e.g. heat seal jaws, guide strips, electrical insulation, release surface).
Operating temperature range and line speed.
Substrate material the tape will be applied to (e.g. aluminium jaws, stainless steel, plastics).
Preferred construction (glass cloth or film) and any requirements for thickness or wear life.
Required roll width, length, and whether you need linered or linerless tape to suit your installation method.
PTFE Tape Constructions
Step-by-Step Application Guide
1.Prepare the surface
Start by cleaning the surface thoroughly. Use a clean cloth and a suitable solvent to remove any contaminants like grease, oil, or dust.
2. Measure and cut
Measure the required length of tape and cut it to size for the area you need to cover.
3. Remove the release liner
Peel off the yellow corrugated release liner to expose the adhesive backing.
4. Apply the tape
Carefully position and apply the tape to the surface, ensuring it is aligned properly and covers the intended area completely. Press gently for optimal adhesion.
5. Smooth out imperfections
Use a roller or flat tool to eliminate air bubbles or wrinkles, ensuring a smooth, even application.
By following these steps, you can achieve a professional-grade finish every time. At Brown International, we supply high-quality PTFE adhesive tapes designed for industrial precision and durability. Contact our team today to learn how our products can enhance your operations. With their non-stick surface and heat-resistant properties, our tapes are built to perform under pressure.
The choice between a liner or no liner for PTFE adhesive tapes significantly impacts both handling and application:
With Liner:
A liner acts as a protective layer over the adhesive, preserving its tackiness and preventing contamination until the tape is ready for use. Liners enable easier handling, precise positioning, and clean processing, especially in production environments where tapes are die-cut, kiss-cut, or custom slit to narrow widths.
Without Liner:
PTFE tapes supplied without a liner are ready for immediate application, which can be advantageous for manual or high-speed automated processes where a liner would slow down production. However, tapes without a liner are more susceptible to premature adhesion, contamination, or damage during handling and storage. They are less suitable for applications requiring intricate die-cutting or precise placement, as the adhesive is always exposed.
