Vacuum Sealer FAQs at

If you're curious about the wonders of vacuum sealing or seeking answers to common questions about these versatile machines, you've landed in the right spot. Whether you're a home cook looking to preserve leftovers or a business owner in the food industry seeking efficient food storage solutions, vacuum sealers can revolutionize the way you handle perishable items.

What is a chamber sealer?

A chamber sealer is a type of vacuum sealer that operates by placing the entire package inside a vacuum chamber. The air is then removed from the chamber, sealing the bag or container and preserving the contents. Chamber sealers are commonly used for high-volume commercial applications.

What is an external vacuum sealer?

An external vacuum sealer is a more compact and portable vacuum sealing option. It utilizes an external vacuum nozzle to remove air from specially designed vacuum bags. External vacuum sealers are often preferred for home use and small-scale food preservation.

What are the main differences between chamber sealers and external vacuum sealers?

The main differences between chamber sealers and external vacuum sealers include:

  • Operation: Chamber sealers require placing the entire package inside the vacuum chamber, while external vacuum sealers use an external nozzle for air removal.
  • Capacity: Chamber sealers are designed for high-volume processing and can seal multiple bags simultaneously, whereas external vacuum sealers are more suitable for individual bags at a time.
  • Size: Chamber sealers are larger and heavier due to the vacuum chamber, while external vacuum sealers are more compact and lightweight, making them easier to store and move.
  • Cost: Chamber sealers are generally more expensive than external vacuum sealers, as they are built for heavy-duty commercial use.

Which type of vacuum sealer is suitable for home use?

For home use, an external vacuum sealer is often the preferred choice. It is more affordable, space-efficient, and meets the needs of most home food preservation tasks effectively.

What are the advantages of using a chamber sealer?

Chamber sealers offer faster and more efficient sealing, especially for large quantities of food. They can handle liquids and liquid-rich foods without spillage. Additionally, chamber-sealed bags have a more professional appearance, making them ideal for commercial use.

Are there any disadvantages to using an external vacuum sealer?

External vacuum sealers may not be as powerful as chamber sealers, limiting the types of food they can effectively seal. They may also have limitations in sealing liquid-rich foods or liquids due to the external nozzle design.

Can I use regular plastic bags for vacuum sealing?

It is not recommended to use regular plastic bags for vacuum sealing. Vacuum sealing requires specially designed vacuum bags that are compatible with the sealer you are using. Regular plastic bags may not provide a proper seal and can compromise the preservation of the food.

Can vacuum sealing extend the shelf life of food?

Yes, vacuum sealing can significantly extend the shelf life of food by removing air and sealing it in an airtight environment. This helps prevent oxidation, freezer burn, and spoilage, keeping the food fresher for a longer period.
