What’s the Best Weld for Polyester Strapping?

Polyester strapping offers a much more flexible material that’s appropriate for all but the heaviest, non-compressible loads.Lets see about the different ways of creating closures for polyester straps. The strap is only as strong as its weakest link, after all, which is the point where it’s joined together.

So which method of closure should you be using when you use polyester?

Seals, Friction or Heat Welding

We have three choices for closing polyester strapping.

  1. The first one is to use a metal closure. This can be a good choice for light-duty, low-volume packaging. With this method, the seal joint is usually less than half of the overall material’s strength.
  2. Friction joint weld, or?friction welding. In this method, rapid vibration creates enough heat to fuse the two ends of the polyester strap together.
  3. Heat welding. This method uses a thermoelectric heater blade to melt the straps together under pressure.

The Type of Strapping Equipment You Use

The type of closure you use for your polyester strapping might depend on the type of equipment you have.

Friction welds are used by all?hand strapping tools?as well as most semi-automatic and automatic?strapping machines. Friction welds have evolved to become the standard in the industry. However, there are still some machines being made with thermoelectric blades, but technology has started to limit their use.
