If your business requires packaging of small parts, you may want to look into the option of an impulse sealer. A sealer uses an impulse of electricity to melt two layers of plastic together. This is most useful for sealing a plastic bag or pouch tightly closed if you are dealing with food items that need to be kept fresh or are worried about lots of small pieces escaping through holes left in a less thorough closure method.

There are a lot of factors that go into buying the proper and perfect impulse sealer for your needs such as its strength, its heating effects, length, thickness, bulkiness, etc. We’ve referenced customer reviews to bring you our list of the top 6 impulse sealers.

FAQ’s

How does an impulse sealer work?

Impulse sealers do their work when an electric current is passed through a conductor to generate heat. This heat naturally causes an increase in the temperature for specified intervals of time which is followed by a cooling period during which the jaws close themselves, causing the molten plastic to be welded together on the plastic bag, creating a seal. Once this is done, the jaws reset and the process can be repeated.

What can be sealed with impulse sealers?

The materials you can weld with your sealer depend totally on your machine. Depending on its configuration and features, an impulse sealer can seal one, all, or some of the following materials:

  • Nylon
  • FEP
  • PET
  • PE
  • HDPE
  • PVC
  • Kraft Paper
  • Polypropylene
  • Tyvek
  • Foil laminates

How big of a sealer is best suited for you?

If you need an impulse sealer for household purposes, then you won’t be needing a machine that is powerful enough for a factory. Just go for an average performing one that is conveniently sized for storage.

If you need one for your business, then you could go for something with a higher-end performance. It might be worth it to find a bigger model that can stay set up all the time depending on how frequently you use it.

If you need something for packaging purposes in a factory, then go with the most powerful sealers that also include high efficiencies of performance (~5000-6000 bags a day).

Conclusion

In the professional world, it is always imperative to put your best foot forward and this list has been curated with this in mind. In the end, however, it is your choice to go with the best sealer for your needs, but if you are looking for quality and value under the same roof, then you need not go any further. This is bound to be your one-stop-shop for an impulse sealer.
