Packaging machines run hot and run all day, so a worn sealing jaw or belt quickly becomes lost production. PTFE (Teflon) for packaging machines solves the two core problems: hot plastic sticking to metal, and uneven seals. This guide explains the three PTFE products used in packaging lines, which one fits which machine, and how to order the right size. It is based on more than 10 years of supplying PTFE belts, fabrics and tapes in Egypt.

Why packaging lines use PTFE

Sealing machines press hot jaws against plastic film. Without protection, melted plastic sticks to the metal, leaves residue and produces weak or broken seals. PTFE has one of the least sticky surfaces available, handles heat according to its grade, resists chemicals and has low friction. The result is cleaner seals, less cleaning and fewer stoppages.

The three PTFE products for packaging machines

1. Self-adhesive PTFE tape on sealing jaws

The quickest and cheapest protection. The tape sticks directly onto the jaw and is replaced in minutes when worn. We supply 80 to 180 micron tape in widths from 10 to 100 mm and wider to order. See self-adhesive PTFE tape.

2. Solid PTFE belts (pull belts)

Closed loops of PTFE-coated fiberglass fabric that pull the bag or package through the sealing jaws and resist sticking to the hot surface. They must match the machine exactly, so we make them to your size. See PTFE belts for packaging machines and thermal PTFE belts.

3. PTFE coated fabric

Rolls of PTFE-coated fiberglass fabric in brown, beige, black and white, sold by the metre or by the roll. Cut it to cover hot surfaces that must not stick. See PTFE coated fabric.

Which product fits which machine?

  • Bag sealing machine: adhesive tape on the jaws, plus a pull belt if the machine feeds automatically.
  • Continuous wrapping or flow-pack machine: solid belts and tape on the sealing jaws.
  • Shrink and automatic packing lines: belts made to the machine size.
  • Heat press or hot plate: coated fabric or a belt, depending on the machine.

How to order the right size

  1. Identify which part touches hot plastic: jaw, pull belt or hot plate.
  2. Measure the jaw length and width for tape, or the loop length and width for a belt.
  3. Tell us the sealing temperature so we can recommend the grade and thickness.
  4. If the product touches food, order food-grade material.
  5. Order a spare so a stoppage takes minutes, not days.

Mistakes that hurt seal quality

Fitting tape on a dirty or hot jaw, so it lifts at the edges. Choosing the wrong thickness. Running past the point where tape or belt is worn. Ordering a belt with an approximate size. Cleaning with sharp tools that scratch the PTFE surface.

Keeping PTFE lasting longer

Keep jaws clean and flat before fitting new tape. Wipe residue with a soft cloth regularly. Set temperature and pressure no higher than the material needs. Check edges and joints often and replace before failure. Keep spares in your machine sizes.

Food packaging

If your machine packs food, specify food-grade PTFE that meets food safety requirements. We supply food-grade materials on request.
