Guide to Choose the Right Vacuum Sealer Bags
Why You Should Invest in a Vacuum Sealer
- Extend shelf life: By removing air, vacuum sealers slow bacterial growth and oxidation, allowing foods to last two to three times longer than standard storage methods.
- Prevent freezer burn: With minimal air contact, frozen foods retain their texture, moisture, and flavor for months (or even years) without those dry, icy patches.
- Preserve flavor and nutrients: Locking in freshness ensures you get the same taste and quality when you finally use your stored food.
- Save space and reduce waste: Vacuum-sealed packages are compact, stack neatly, and help you store more in the same amount of space.
- Perfect for sous vide and quick marination: Removing air allows marinades to penetrate faster, and sealed bags can go straight into a water bath for precision cooking.
Two Main Types of Vacuum Sealers: Chamber vs External (Edge)
Chamber Vacuum Sealers
- How they work: The bag is placed inside a chamber, and both the inside of the bag and the chamber itself are depressurized before sealing.
- Advantages:
- Handles liquids and wet foods with ease.
- Stronger, more consistent vacuum seal.
- Ideal for large quantities and commercial use.
- Drawbacks:
- Bulkier and heavier than external models.
- Higher price point and requires more counter space.
External (Edge) Vacuum Sealers
- How they work: The machine removes air directly from the open end of the bag, then seals it shut.
- Advantages:
- Compact, lightweight, and generally more affordable.
- Quick and easy for everyday sealing of dry foods.
- Drawbacks:
- Less effective with liquids or very moist foods.
- Requires special textured bags to ensure air removal.

Vacuum Sealer Maintenance Tips
Taking care of your vacuum sealer will ensure it lasts for years:
- Clean after every use: Wipe down sealing bars and surfaces to prevent food residue buildup.
- Replace sealing gaskets: Over time, gaskets can wear out, reducing suction power.
- Avoid sealing with wet bag edges: Moisture on the sealing strip can weaken the seal.
- Use the right bags: Always choose bags designed for your machine’s type (textured for external models, smooth for chamber models).
- Store in a cool, dry place: Prevents damage to internal components and prolongs lifespan.
Conclusion
The best vacuum sealer for you depends on your budget, how often you’ll use it, and the type of food you’ll be sealing. From affordable beginner models like the Geryon to commercial-grade chamber sealers like the VacPak-It, there’s an option for every kitchen and every skill level.
By investing in the right machine, you’ll keep your food fresher for longer, save money, and open the door to cooking techniques like sous vide and quick marination.
