If all you’re looking to do is to vacuum seal dry food items, then you won’t have many issues. On the other hand, vacuum sealing liquids can be messy and disastrous, especially if you don’t know how to do it right. The most significant problem with vacuum sealing liquids is having a poor seal that splits before you remove it.

Then again, you don’t need to worry about that anymore. You can learn how to vacuum seal liquids with FoodSaver by following the tips and tricks provided below.

How to Vacuum Seal Liquids with FoodSaver

Are you tired of having to throw away spoiled sauces, juices, and other liquids? With this guide, you can save yourself a lot of mess and a lot of money by not having to toss out that extra sauce.

Here are the techniques for sealing liquids using a FoodSaver:

Keep Your Vacuum Sealer Above the Bag

Keep Your Vacuum Sealer Above the Bag

It really is as simple as that. The method involves using one hand to support your bag while the other remains on the vacuum sealer itself. It’s an easy way to seal your liquids in a fast manner.

When choosing this method, it is better to have a more modern FoodSaver that enables you to vacuum and seal by touching a button.

All you need to do after filling the bag with the liquid and hanging it off of the edge of the counter is to lock the sealer into place. Then, press the vacuum and seal button to close the bag.

Freezing Method

Using the freezing method is one of the more popular ways of vacuum sealing liquids, and it’s very simple to do. Liquids can be frozen in plastic containers, and it is easier to remove because it’s flexible. If you need to know how to vacuum seal liquids with FoodSaver because you intend on using a sealer bag, you have a few different options available to you.

When sealing liquids in a sealer bag, it’s suggested that you first pour the liquid into the bag and then place it into a bowl, container, or use something stable that is going to keep the bag propped up. Once you’ve done that, freeze the liquid for an hour.

For example, if you are using your vacuum sealer to seal soup, you can freeze it for an hour and remove it from the freezer when it is only partially frozen. Then, all you need to do from there is to seal your liquid in the same manner that you use to seal your dry food.

It’s important to realize that you can’t just seal liquids in the same way that you seal dry foods unless the fluid is partially frozen first. There is a little more work that gets put into sealing liquids, so if you know you are going to be sealing more fluid than dry foods, it’s best to consider looking into a high-quality FoodSaver.

Other Methods to Vacuum Sealing Liquids

Paper Towel Method

The paper towel method can seem really out there, but it does actually work. What you need to do is to fold one, or more, pieces of paper towel into a flat strip that measures the same length of the bag you are sealing. After that, place the paper towel above the lid of the vacuum sealer but make sure the paper towel doesn’t get clamped.

The paper towel that you use is going to absorb any liquid that might seep out as you seal your bag. You might find yourself asking about the paper towel that’s in the lid afterward. While it is okay to leave it in there, you might want to get it out, and there is a trick to doing that.

If you want to make sure that you can remove the paper towel after you have sealed the liquid in, you need to leave a little extra bag space than you usually might. You can use the extra room to vacuum seal above the paper towel and then cut off the portion with the paper towel once your bag is adequately sealed.

Other Methods to Vacuum Sealing Liquids

Believe it or not, FoodSaver has actually released liquid blocker bags in quart sizes that make it easier to seal your liquids. These FoodSaver bags have a built-in blocking strip that keeps your juices and any moisture from escaping the pocket during the vacuum process.

Unfortunately, the FoodSaver liquid block bags are more expensive than ordinary bags, but if convenience is worth more, the bags might be an excellent fit for you. Using liquid block bags is a great alternative to having to go out and buy a chamber vacuum sealer, which is far more expensive.


It’s been concluded that vacuum sealing your liquids can be a nightmare, but as long as you know the right process to follow, you’re going to be okay. Any horror stories that you might hear are likely coming from people that didn’t do enough research before sealing their liquids.

Following the tips above is going to give you the experience that you need. Who knows? Soon enough, you might find yourself spending the time to teach others how to vacuum seal their liquids properly.
