Most heat sealing machines available today are not designed for longevity. In addition to the machine, it mostly depends on the type of sealing work you intend to do and how frequently as to decide approximately how long a heat sealer will last.
The lifespan of a heat sealer is of course not an exact science.
To emphasise the point again most sealer machines on the market are made with inexpensive materials that do not perform well for demanding projects.
Our heat sealers are professional & robust machines that are built to last. We also supply spare part kits for the most common consumables which may deteriorate with repeat use.
Here you can see there is more of a ‘value equation’ in play, as one of our machines purchased with a spare parts kit is to be seen as an investment that with care could potentially last well into the long term.
