This Metronic can seal bags as long as 12 inches and 2mm wide. The thickness of the seal remains same at 10mm. The included adjustable timer holds the responsibility for coming up with accurate and consistent seals throughout. Another difference between this sealer and its bigger version is the change in the material of the body. Where the 16” version is made out of a combination of steel and metal, this sealer is made out of Aluminum which makes it slightly more durable and a lot sturdier than its elder brother.

An adjustable timer is there for making sure that consistent seals are created every time irrespective of the thickness of the bag being used. Apart from this, the Ultrasource also includes the facility to not just seal, but trim and seal bags in a single go.

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 jaws close themselves, causing the molten plastic to be welded on the plastic bag, thus creating a seal. Once this is done, the jaws reset and the process keeps repeating.

What all can be sealed with Impulse Sealers?

What all materials you can weld with your sealer depends 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?

The answer to this is totally dependant on your own needs. If you need an impulse sealer for household purposes, then you won’t be needing a machine that is powerful enough for factory purposes. Just go for an average performing one that is more than enough to get things done.
If you need one for your shop or something, then you could go for something with a little high-end performance and also having a considerate amount of quality in its packing.
If, however, you need something for packaging purposes for a factory, then you must go with the most powerful of sealers that also include with them high efficiencies of performance in a day (~5000-6000 bags a day).

It does not depend ‘why’ you need an impulse sealer. 99 times out of 100, it is to satisfy some professional task and in the remaining 1% situation would you be needing it for some personal task and in the professional world, it is always imperative to put your best foot forward and this list has been curated while keeping the same in mind. In the end, however, it is your choice to go with any sealer that you like, but if you are looking for quality and value under the same hood, then you need not go any further. This is bound to be your one-stop-shop for an impulse sealer.
