Controlling Liquids When Vacuum Sealing

Most raw food and some cooked foods have some or a lot of liquids in them

Liquids, when vacuum sealing is your worst enemy and I hear it all the time “ Yeah the blood goes up to the top but that’s OK”. Well IT’S NOT OK

Here’s Why

If liquid gets up into the area that is to be heat sealed it simply will not seal properly, it may give the appearance that it has but there is a good chance it will let go and when you go to the freezer a few months later your meat has freezer burn. I here it all the time. Also if the liquid has gone to the top of the bag it probably has been sucked into you vacuum sealer and over time you will damage your vacuum sealer

This also is the case if you use any of the hand pump or vaclock machines with the valve in the bag. The liquid will stop the valve from sealing and the liquid will damage the hand held pump over time


  • Leave 80mm – 100mm above the food when making bags from roll film
  • Use pre made bags that are 80mm – 100mm bigger than the food
  • Very damp food, roll the top of the vacuum bag down so you do not get moisture on the top area of the vacuum bag where it is to be sealed

Solution no. 1

All raw meat has liquid on the out side and the inside of it, so simply pat the meat dry on a piece of paper towel before you put it into the vacuum sealer bag

Solution no. 2

Roll a piece of paper towel up and put it inside the bag from side to side and between the food and the seal area. This is great if you are doing fish. The liquid will get to the paper towel and get soaked up by it while you get all the air out and seal it up

Solution no. 3

If you are vacuum sealing very liquid food such as soaps and stews, make the bag and put the soap in then place the open bag in the freezer for ¾ of an hour so that it partially freezes the soap. Vacuum seal the bag and because it is partially frozen the liquid will not move and you can still push it down flat to pack away

Final Note

If any liquid does get close to the sealing area either shut the vacuum sealer down or switch it manually over to seal and then drop the bag down and do a second seal to make sure. All of the ZeroPak machines have these functions

If you get liquid into the seal area using any machine, the bag will not seal properly, simple really
