Vacuum Sealer 5

A vacuum sealer is a versatile tool that has taken the culinary world by storm. Known for its ability to extend the shelf life of food, it has become a staple in many households and commercial kitchens. But the uses of a vacuum sealer extend beyond food preservation. From home cooks to outdoor enthusiasts, more and more people are discovering the benefits of owning a vacuum sealer. In this comprehensive guide, we’ll explore what to use a vacuum sealer for, how it works, the types available, and how to choose the right one for your needs.


A vacuum sealer is primarily used for preserving and extending the shelf life of various food items such as meats, fish, vegetables, fruits, and grains by removing air from the package and sealing it. It also offers protection from freezer burn, efficient storage, cost savings, enhanced taste, and time-saving meal preparation. Additionally, vacuum sealers can be used for preserving non-food items like first aid kits, camping supplies, electronics, important documents, collectibles, and clothing.

What Is a Vacuum Sealer and How Does It Work?

A vacuum sealer is a device that removes air from a package and then seals it, preserving the freshness and quality of the contents inside. It works by placing the items to be sealed in a plastic film package or a sealable bag. The vacuum sealer then removes the air from the package, creating a vacuum inside it. Once the air has been removed, the sealer uses a heated seal bar to fuse the sides of the bag, creating an airtight seal that prevents air from re-entering the package.

There are two main types of vacuum sealers: chamber vacuum sealers and external vacuum sealers. Chamber vacuum sealers have a sealed chamber where the product is placed inside a vacuum bag, and the air is removed from the chamber and the bag simultaneously. External vacuum sealers, also known as edge or suction vacuum sealers, involve attaching a bag to the vacuum-sealing machine externally. The machine removes the air and seals the bag outside the machine, using a heat sealer.

Types of Vacuum Sealers

There are various types of vacuum sealers available in the market, each with its own advantages and disadvantages. The main types of vacuum sealers are:

  • Chamber Vacuum Sealers: These sealers are designed for commercial use and high-volume applications. They require the entire package to be placed inside the vacuum cavity area of the machine. Chamber vacuum sealers are available in various models, from small tabletop machines to large double chamber machines.
  • External or Suction Vacuum Sealers: These sealers are more common and suitable for home use. They work by sucking the air out of a compatible plastic bag before sealing it by melting the ends of the bag together. External vacuum sealers are less expensive than chamber machines and are ideal for operations that occasionally seal foods.
  • Handheld Vacuum Sealers: These are the least expensive and smallest type of vacuum sealers. They attach to specially made plastic bags or containers and evacuate the air through an integrated valve. However, they usually have smaller motors and are inferior at creating a strong vacuum compared to other types of vacuum sealers.
  • Retractable Nozzle Vacuum Sealers: These are a type of non-chamber vacuum sealers and are considered more commercial than edge-type sealers. They are available in various models with different features and capabilities.
  • Edge Vacuum Sealers: Also known as external clamp vacuum sealers, these machines require the use of special bags often referred to as channel or mesh bags. They are similar to external or suction vacuum sealers in function.

Key Advantages of Using a Vacuum Sealer in the Kitchen

Using a vacuum sealer in the kitchen offers several key advantages:

  • Extended shelf life: Vacuum sealing deprives food of oxygen, inhibiting the growth of mold, bacteria, and fungi, thus extending the shelf life of various food items.
  • Protection from freezer burn: Vacuum sealing creates an air-tight environment that prevents the formation of ice crystals, which cause freezer burn, keeping food fresh and moist for an extended period.
  • Efficient storage: Vacuum-sealed food takes up less space in your refrigerator or freezer, allowing for better organization and easier visibility of stored items.
  • Cost savings: Vacuum sealing allows you to buy perishable items in bulk and preserve them for future use, reducing food waste and saving money on groceries.
  • Improved taste and marinating: Vacuum sealing helps retain the juiciness, moisture, and flavor of food, and it also allows for more effective marinating and seasoning.
  • Time-saving: Vacuum sealing enables you to prepare and store pre-portioned meals in advance, saving time during meal preparation.
  • Preservation without additives: Unlike other preservation techniques, vacuum sealing doesn’t require the use of chemicals or other additives to keep food fresh.
  • Year-round freshness: Vacuum sealing helps maintain the freshness of seasonal items and perishable foods like vegetables, meats, nuts, and pasta.

Foods That Are Best Suited for Vacuum Sealing

Certain foods are better suited for vacuum sealing than others. These include:

  • Meat: Vacuum sealing meat helps preserve its freshness, flavor, and texture while preventing freezer burn.
  • Fish: Like meat, vacuum sealing fish extends its shelf life and maintains its quality.
  • Vegetables: Vacuum sealing vegetables preserves their color, flavor, and nutrients, making it especially helpful for seasonal produce.
  • Fruits: Vacuum sealing fruits helps maintain their flavor and texture, allowing you to enjoy them throughout the year.
  • Grains and legumes: Vacuum sealing grains and legumes prevents them from becoming stale or infested with bugs, making it a great option for bulk purchases.
  • Cheese: Vacuum sealing cheese can extend its shelf life from 1-2 weeks to several months in the fridge.
  • Bread: Vacuum sealing bread can help maintain its freshness and prevent it from going stale.
  • Soups and stews: Vacuum sealing soups and stews can help preserve their flavor and quality.
  • Dry goods: Vacuum sealing dry goods like flour, rice, sugar, and snacks can increase their shelf life.
