Best Impulse Heat Sealer for Food Storage

by Tommy Grant

If you are looking to seal plastic or mylar bags, an impulse heat sealer can make it easy. Load the bag, position the bag in the sealer, and then put the seal arm down to seal it in an instant. Easy enough, but the best impulse heat sealer does it quickly, efficiently, and doesn’t break the bank. There are several options to consider when it comes to an impulse sealer: capacity, speed, maintenance, etc.

This is where we come in. We’ve researched the best impulse heat sealers, tested them, and now the results are in: the overall best, a budget option, and an upgrade option. If you need to seal some bags for food storage (or other projects), one of our recommendations will close the deal.

DIY, Versatile, and Effective

Skip the dedicated impulse heat sealer and re-use a small tool you already own.

An impulse sealer isn’t completely necessary, especially for quick jobs or those just starting out. It may take a bit more time and some practice, but you can heat seal with small appliances you may already have on hand- hair straighteners and clothes irons.

Hair straighteners are ideal since they have a long and narrow profile to reach across the opening of the bags you are trying to seal, and you don’t have to lay the bag on a surface to get it done.

Save yourself a few bucks and use what you already have if you aren’t tackling large projects or an entire pantry of food storage.

The Heat Sealers We Compared

Our research narrowed the field down to the several heat sealers that we compared: Wallaby, Vimi, Harvest Right, MSW, Metronic, and more.

You can see our full list of review criteria below in the What to Look For section, with an explanation for each.

We focused on sealers with a maximum capacity of 12 inches or less just as a baseline to compare costs and features. All of our picks come in a few size options, including 8″ and 16″.

We’re always looking for new and better equipment, so if you have an impulse sealer that you swear by let us know in the comments. Also, if you have a DIY solution as we do for our budget option, let us know. We review most of our tested equipment annually, so we can always get it in the next roundup round and see if it makes the cut and we can see if it will beat out our top picks.

What to Look For

The best heat sealers have several important features to look for:

  1. Value
  2. Capacity
  3. Speed
  4. Maintenance
  5. Quality

When you get the right blend of these, you can find a sealer that will consistently close bags without any leaks. Below, we break down what each of these features means for the impulse sealers that truly set themselves apart.

Value: Cost vs. Benefit

The amount of money you spend on something like a heat sealer shouldn’t blow out your entire budget. Don’t go overspending or overdo it. Budget according to your risk and your needs rather than just spending lavishly.

On the flip side, you don’t want to go too cheap or just plain get the wrong thing. There are handheld heat sealers that are no different than a hair straightener but are marketed and marked up as heat sealers. Don’t go out and get something scammy- you’ll be relying on the seal it makes.

You never want to spend too much money on one resource, especially something like a small appliance with a niche use. It’s better to diversify your preparedness gear to make sure you are covered for a wide range of scenarios.


There is a wide range of lengths available for heat sealers, and the larger you go the more versatile they are. For home use, you’ll find most impulse sealers go up to 18″, which can typically handle two-gallon bags.

Capacity can also be measured by the thickness of the mylar bags the impulse sealer can close. Very thick bags may need a higher heat setting and a longer set time to completely seal.

Check the manual of your specific model to see which setting to use for the various thicknesses of plastic and mylar.


Impulse sealers are meant to be quick. You don’t need to sit the arm on the bag and wait- it should only take a few seconds to seal depending on the thickness of the bag.

Both models we suggest have a finish light, and depending on the instructions you may want to delay a little past that to ensure a good seal.


The main consumable parts of an impulse heat sealer are:

  • Fuses – be sure to have spares on hand to easily swap out blown fuses
  • Heat strips – a heating element that can be replaced quickly when it stops working
  • Pads – pads become damaged with use, so you need to be able to swap these as well.

All of these are relatively easy to swap out on most models we researched and tested, so combined with the maintenance instructions you shouldn’t have much trouble. Our upgrade pick did come with plenty of spare parts to make maintenance much easier. The quality of the parts can extend their life, making maintenance less frequent.


When you invest in any appliance, quality is important. Especially if that appliance is a part of your emergency plans. Besides the manufacturing quality inherent in an impulse sealer, the service quality is important too.

You’ll also need a reliable supplier for your sealer because there are replaceable components inside of them that you will either need to have on hand or be able to get them quickly. In our tests, our upgrade pick (Wallaby) and Harvest Right had the two most responsive service departments.

How to Use an Impulse Heat Sealer

Using an impulse heat sealer may seem easy at first, but it can be a little finicky and require some maintenance. Most have replaceable fuses and sealer bars available. You’re also dealing with heat so you always need to be careful what you put into a sealer to make sure you aren’t starting a fire or creating toxic fumes.

Here is Dimitri on YouTube giving some great tips on how to use it with plastic:

Who Needs an Impulse Sealer?

Impulse sealers are not a necessity, but they are very nice to have on hand if you plan on doing a lot of sealing. People investing in food storage, for instance, really stand to benefit. For those who plan to use mylar bags and oxygen absorbers, it can pay off to make sure your seal is good by using a proper tool.

We recommend an impulse heat sealer for your:

There are other uses for heat sealers, and they can be used for a wide range of storage purposes.
