How to seal our Vacuum Seal Bags on a Home Sealer

How to seal our Vacuum Seal Bags on a Home Sealer


1. Make two folds to the top of the bag prior to use. To do so, fold the bag in half length-wise. Fold a 3cm wide triangle at the top. Press to crease then unfold (see illustration to below). 

2. Add contents to the vacuum seal bag, taking care not to get the top of the bag wet as this can negatively impact the vacuum function.

3. Take the pre-folded edges, double fold over on the inside of the bag, press together and hold to form vacuum funnel.

4. Press out excess air, place open end with folds in the vacuum sealer, lower lid, and lock. Leave 3-4 inches at the top of the bag to extract the air.

5. Press ‘manual air extraction’ until the desired vacuum is achieved and heat seal bag closed. Take care not to over extract air as you may draw moisture into the vacuum chamber of your sealer.

  • Always keep the bag upright to prevent any moisture running to the open end of the bag.
  • Do not over extract air as you will draw moisture into the tubing and chamber.
  • When sealing fish or shellfish, dry with a paper towel prior to bagging to absorb any excess moisture.
  • When using a home vacuum sealer, the vacuum function may take 2-3 times longer than traditional vacuum seal bags to extract air.
  • Ensure you have used the fold mentioned above to create a vacuum funnel for air to be extracted.
  • If your machine isn’t working properly, run the vacuum function 2-3 times while the machine is empty.


    Our vacuum seal bags are made from bio or plant based bioplastic and are regenerative in the home compost. In the presence of moisture, soil, heat and oxygen the biofilm is broken down and renewed by soil organisms, fungi and worms to become soil.

    1. Wash bag in warm soapy water and dry.

    2. Reuse bag.

    3. When you are finished with the vacuum bag, rip or cut the bag into strips and place in a warm home compost.

    4. Cover or lightly turn compost
