Then check out this post.

I reviewed ten of the best portable heat sealing machines you can currently find on the market. Find out more about their design, compare their features, and check out my advice on what are the things you need to consider when purchasing one.

The Rundown

What Heat Sealers Are Portable?

There are various models you can choose from, depending on the power source and design. You can choose an electric or battery-powered model. It can be a small, handheld sealer or a classic-sized one with a lightweight design. The most important thing is that you can take such a sealer with you in your RV, mobile home, boat, camping trip, or work.

Key Components Of Portability

To ease up the search for such a portable model, here are the key components you need to focus on if you want to find the most suitable model.

• Size. In the terms of heat sealers, size is certainly one of the most important factors. There are mini models that feature about 5 inches big units and those standard-sized ones that are about 12 inches big.
• Weight. Mini heat sealers weigh just a couple of ounces which makes them ideal for traveling, trips, and office, as well as those small sealing actions you need at your home, for example for chips and snacks. Standard models weigh up to 10 pounds. They are great for sealing classic food bags and to be used in motor homes.
• Design. This component determines the way you can use your mini sealer and store it when you don’t need it. Thanks to its design, the mini sealer can be stored in a bag or a pocket, and used anywhere, while the standard model needs a drawer or cabinet, and can be used in those places where you have a power source.



• Safety. In the terms of portability, safety is an important component. If you want to carry your new heat sealer around with you, it needs to have a safety lock.

Can I Heat Seal Any Plastic Bag?

Yes, almost any type of poly bag can be heat sealed. That includes polyethylene, polythene, and polypropylene bags. You can also heat seal chip bags and other snacks.

Different Model Options

You have 3 model options of portable heat sealing appliances. Here are the details.

• Jaw sealers are handheld models that are designed with 2 jaws. So in order to use such a model, you need to press together two of its handles. These sealers are designed to fit comfortably in the palm of your hand and can work with different types of bags, including plastic, kraft paper, and cellophane.
• Impulse sealers are actually standard heat sealers designed to be used at the top of the table or countertop. In order to use this model, you need to lower down its top which features a flat heat sealing bar.
• A mini bag sealer is a truly small heat sealer that can fit in the pocket of your shirt. It usually features an aesthetic and modern design and it is great for heat-sealing snacks and potato chip bags.

Biggest Pluses Of Portable Sealer Machines

As with any other sealing model, this too comes with many advantages and benefits. Here are just a couple of them which will make your decision on buying this handheld kitchen appliance a lot easier.

Seal Customization

What is great about portable mini handheld sealers is their ability to create custom and unusual seal patterns. This is great if you have a business too.

Double Seals

With these models, you can easily create double seals for extra oxygen and moisture barrier protection.

Keep Food Fresh & Tasty

Portable small sealers will keep almost any type of food fresh and tasty for months. That includes snacks, cookies, fruits, vegetables, meat, fish, nuts, herbs, and more, whatever you need, wherever you are.

Minimize Your Waste

While traveling, you tend to open a lot of different food and snacks. Now, by using a convenient small sealer, you will minimize waste and save money.

Quiet Performance

Small heat sealers produce as minimal noise as possible. That can be convenient if you don’t want to disturb your colleagues at work or kids at home.

Easy To Use

Most heat sealers are really easy to use as they feature a start button and a couple of sealing modes. They can easily be used by both beginners and professionals.

Here Are The Details On Features & Functions

Before buying a new heat sealer that is defined by its portability, there are some specs and features you need to know which will help you in deciding which model is a perfect match for your household.

Two Construction Options

There are 2 possibilities in the terms of construction. Standard heat sealers can be made from plastic or stainless steel. Both materials are strong and durable. Mini heat sealers are made only from plastic.

Sealing Power

The sealing power of the heat sealer is what determines the efficiency of the created seal. Most portable models come with multiple heat sealing levels that allow you to adjust the temperature depending on the type of bag you want to seal.

Sealing Width

Depending on the width of the flat wire element, sealers are available in 2-3 mm, 5 mm, 8 mm, or 10 mm. If you want to seal thicker materials, you need a wider seal width for better heat operation.

Heating Time

Another thing you need to take into consideration is the time it takes the sealer to heat up. Units that require an electrical power source are usually ready to be used immediately while the battery-operated ones need a few seconds or minutes to heat up.

How Does A Portable Mini Heat Sealer Work?

It works a bit differently than standard models. While for a classic heat sealer, you just need to place the opening of the bag in the heating wire and then close it with the top, a mini model works a bit differently but on the same principle.

1. Heat up the sealer for a couple of seconds or minutes, depending on what the official instructions say.
2. Place the opening of the bag between the opened sealer.
3. Lower the top and press the bag. Move the sealer from one side of the opening to the other. Do not open it until you go all the way.
4. That’s it, your bag is now closed and sealed.

Can I Use An Iron Instead Of A Heat Sealer?

You might, but you shouldn’t. It is not safe to seal with it and it might lead to a fire. The same goes for a hair straightener which can get damaged if you use it for heat sealing.
