How Vacuum Sealers Work: Everything You Need to Know Before Buying One

If you’re wondering how vacuum sealers work, this guide will break down the process and help you choose the right one for your needs.
What is a Vacuum Sealer?
A vacuum sealer is a device that removes air from a specially designed plastic bag or container and then seals it to prevent air and moisture from entering. This process extends the shelf life of food, prevents freezer burn, and maintains flavor and texture over time.
How Vacuum Sealers Work: Step-by-Step Process
Understanding the mechanics behind vacuum sealing can help you make the best use of the technology. Here’s how the process works:
Placement of Food in the Vacuum Bag
Place the food or ingredients inside a vacuum-sealing bag, ensuring there’s enough space at the top for proper sealing.
Air Removal Process
The vacuum sealer extracts air from the bag using a pump or suction system. Removing oxygen slows bacterial growth and prevents spoilage.
Sealing the Bag
Once the air is removed, the sealer applies heat to the opening of the bag, melting and sealing the plastic together to create an airtight closure.
Storage and Preservation
The vacuum-sealed bag is now ready for storage in the refrigerator, freezer, or pantry, keeping food fresh for longer periods.
Types of Vacuum Sealers
There are different types of vacuum sealers available, depending on usage and requirements. Here are the main types:
1. External Vacuum Sealers
- Ideal for home kitchens and small businesses.
- Uses suction to remove air from the bag before sealing.
- Compatible with pre-cut vacuum-seal bags.
2. Chamber Vacuum Sealers

3. Handheld Vacuum Sealers
