It is a device that removes air from a plastic bag and seals it for future consumption. Typically, it is used to preserve food. However, in some models, they can be utilized for other purposes, like saving documents, shirts, etc.
The basic models have suction motor and heat sealer. But other commercial-grade units include air compressor to further suck the air out of the bag.
Most of the time, it is used with food items, especially perishable ones. People utilize this machine to retain food’s freshness for a longer period of time. This method of preservation is said to be more effective than when you left it open to the air. It will also prevent food from freezer burn.
Standard units come with only three options to seal food. First, food items are placed inside a plastic bag. Then, the open end of the bag is placed in the machine. The sealer will vacuum the air out of the bag.
Once the air is removed, the unit seals the bag. But not all units can perform this function. By sealing the bag, it means heating and melting the plastic to create a solid closure. When you need to open it, it needs to be cut below the heat seal.
Other units, on the other hand, have special functions that allow users to create a custom-sized bag from a roll. You can cut the plastic to your desired length.
For larger units, they have attachments that let you vacuum special canisters. They come with a hose that you can attach to the sealer.
Some units offer several speeds, letting you customize the amount of pressure that you can place on the food. They are especially great to avoid crushing of delicate foods.
Why Do You Need The Vacuum Sealer?
There are several advantages of using a food vacuum sealer, regardless of the type and model you have. Its major benefits will include:
- Preserving the nutrients in your food.
- Maintaining freshness of the food.
Other benefits of vacuum sealing your food are listed below:
Avoid freezer burn
When you freeze your food in a freezer, it can be “freezer burned.” But this can be avoided by vacuum sealing your food. The sealer will take out all air from the plastic preventing your food from getting freezer burned.
Freezer burned will result when there is air surrounding the plastic, which causes condensation and formation of ice crystals.
Because it prevents freezer burning, your food stays fresher and its taste is also better even if you store it for a longer period of time.
Buy in bulk
Buying in bulk will usually result in spoilage, even though it allows you to save money. By properly storing it, your food can last longer.
Thanks to the best vacuum sealer on the market, you can now purchase food in larger quantities without having to worry about spoilage. You can keep it for days, weeks or even months.
A vacuum sealer is especially useful when you need to find food items on sale. It is also great if you need to store the items and pack them for an upcoming event that you are planning.
The best food vacuum sealers are not just great for those who want to save money in purchasing food items on sale but they are also useful for people who wish to lose weight.
Portion control is one of the most recommended methods of losing weight. With the use of a food sealer, you can easily make portion sizes of your meals and store them in your fridge.
If you wish to have just three ounces of chicken per serving or meal, for instance, you can measure out the size and seal it. When you need to eat, you do not need to weigh and measure because your meal has already portioned out ahead.
With that in mind, dieting or making portion sizes becomes easier and more pleasurable.
Or you can also ask the supplier to weigh and measure your food as you purchase it. When you are ready to cook it, everything has been prepared allowing you to cook and enjoy your food a lot quicker than before.
Frozen foods and meats tend to lose their flavors. The reason for this is that ice crystal formation can cause the food to change. As a result, it loses flavor when heating it.
Then, if it is not frozen properly, it can easily absorb others from other food items in the freezer. These other food items can take away the flavor or mask the original taste of the food.
Another thing that will be lost because of improper storage is the nutrients of the food because of the air present in the plastic bag or container.
With the help of a vacuum sealing unit, your food’s flavor and nutrients are retained, besides preventing it from absorbing the flavors and odors of other units in your fridge or freezer.

Types of vacuum sealers
The main goal of the sealer is to remove the air from an oxygenated environment before sealing the container. In this way, it prevents air from entering the de-oxygenated atmosphere.
One of the reasons people use food savers is of hygiene. With it, you can control the environment where your food is stored. Because there is no oxygen in the container or plastic bag, chemical reactions will not take place. In other words, it prevents aerobic bacteria from thriving and feeding on your food.
Another reason people are using this type of device is that it lessens the volume and space it takes up for the food to be stored in the fridge or cupboard. That said, it allows you to store more food.
There are different types of sealers but the most common are the nozzle, chamber and channel.
Nozzle Vacuum SealerChannel Vacuum SealerChamber Vacuum Sealer
If you want something more reliable and a bit stronger, you could purchase a Nozzle Vacuum Sealer. These are a little more versatile, as they use a retractable nozzle to remove the air from the bags. This means that you don’t need specially textured plastic materials in order to store your food. Another neat feature is the fact that they allow you to use a gas, like nitrogen, to increase the preservation process. The downside here is that this technique creates uneven sealing, and thus it might take longer for the products to be cooled off.
