Step 4: Submerge the Bag

  • Lowering the Bag: Slowly lower the bag into the water while keeping the top of the bag out of the water. The pressure from the water will start to push air out of the bag.

  • Watch for Bubbles: Continue to lower the bag until you see air bubbles escaping from the bag. This indicates that air is being displaced.

Step 5: Seal the Bag

  • Seal While Submerged: As air continues to escape, seal the top of the bag just above the water line. Ensure there are no air pockets left in the bag.

  • Double-Check the Seal: After sealing, check the bag for any leaks or unsealed areas to ensure a tight closure.

Pro Tip:

Use a vacuum sealer designed to work with bags that have a channel. This can help ensure that water does not seep into the sealer during vacuum processes.

Step 6: Complete the Process

  • Final Check: Once sealed, check for any remaining air. If the bag is not perfectly sealed, you can repeat the process or reattempt sealing.

  • Store Properly: Place the vacuum-sealed bag in the refrigerator or freezer, depending on your storage needs. Foods vacuum sealed can last much longer than non-sealed alternatives.

Common Mistakes to Avoid

While vacuum sealing with water is straightforward, mistakes can arise. Here’s what to watch out for:

Not Using the Right Bags

Always use bags specifically made for vacuum sealing. Regular plastic bags can easily tear or leak, defeating the purpose of vacuum sealing.

Over-Packing the Bag

Ensure to leave enough space at the top of the bag for proper sealing. Overstuffed bags are prone to leaks or improper sealing.
