Whether you're saving this year's strawberry harvest fresh from the garden or saving last night's stroganoff for another meal, a vacuum packer can be a great tool. Vacuum seals work by removing air from the storage bag and then sealing the bag before the air can return. In combination with refrigeration or freezing, vacuum packaged foods can be stored safely for a long time.
However, choosing the right vacuum seal can be a challenge. There are many different brands to choose from and often many different models from each brand. This article gives you a basic idea of what features to look out for and how to determine which features are right for you. However, if you are also looking to buy vacuum sealers for your home usage then look at this site where they have a lot of options.

Automatic and manual mode:
Most vacuum sealers are available in automatic mode. This mode does most of the work for you, testing the air pressure to shut it off when a certain pressure is reached, and then automatically starting the sealing process.
For most casual consumers, this is ideal and takes a lot of the guesswork out of vacuuming food. For more experienced users and for more sensitive applications, some machines offer a manual mode. The user can then observe the process itself for more precise control.
While most models provide a single vacuum pressure, some devices allow the user to adjust the amount of pressure for better control. Again, this is more or less important depending on how you plan to use your vacuum sealer. Finer items may require less pressure to prevent damage. If the condition of the item to be sealed is important, it may be necessary for you to find a variable pressure unit.
