What is vacuum food packaging?
Before we describe the benefits of vacuum food packaging, we will explain it. Well, vacuum packing is the best way to protect food. It consists in placing the selected product in a tightly closed package with the amount of oxygen reduced to a minimum.
Why is oxygen reduction so substantial? You certainly know that oxygen creates excellent conditions for the development of microorganisms. Therefore, food that oxidizes just spoils. Vitamins oxidize, mould develops, and food changes taste and smell. It is food spoilage that makes vacuum packaging of food necessary.
How to vacuum-pack food?
Vacuum food packaging is not complicated. All you need is basic knowledge and proper equipment to pack your food properly.
What do I need to vacuum-pack food?
If you want to vacuum pack your food, you should invest in a vacuum food sealer. This sealer is a special device that allows you to pack food perfectly. Such a welder performs two very important functions. The first is to suck the air out of the bag you pack the food in. The second function is to close the package by welding its edges tightly.
You can easily get food vacuum sealers from our Food Vacuum Sealer store. Remember, if you are looking for a vacuum food sealer, there are several aspects to consider:
- The hardware must be solid. European producers offer the best quality food sealers.
- The hardware must be easy to use for you.

The vacuum food sealer alone is not enough. You also need to have the right food packaging accessories. For example, you will need special bags and foil for food vacuum packing. Choose bags and foils that have been specially designed for welding machines.
Attention! Never use ordinary plastic bags. Most of them are not durable and will be destroyed if you try to heat them. Besides, You should not use even solid plastic bags for food packaging. They are made of poor-quality plastic. They are also often not BPA free. By purchasing special bags and foils for vacuum packaging, you can be sure that your food will be safe.
