What Is a Gas-Filling Machine?
A gas-filling machine is a packaging machine that fills a sealed container with gas.
They can also be used for vacuum packaging and cooking applications without adding gas. A wide lineup of machines is available, from small to large, depending on the size of the packaged product. They are designed to reduce gas consumption while increasing efficiency by increasing the gas displacement rate.
Uses of Gas-Filling Machines
Gas-filling machines are used for packaging food, medical equipment, etc. Filling sealed containers with inert gases such as nitrogen or carbon dioxide prevents oxidation and preserves the freshness of food. In the context of medical instruments, it is used for packaging syringes and syringes to prevent dust and impurities from adhering to them. Because of the sterility it can provide, vacuum packaging is used when hygiene is paramount.
Inert gases are stable gases that do not affect other substances. Nitrogen and carbon dioxide are the most common. Since these gases are originally present in the air, they are characterized by their high safety.
Principle of Gas-Filling Machines
The air in a pack containing food, medicine, etc. is removed to create a vacuum, and then the pack is filled with inert gas or other gases to seal it. When vacuum-packing, gas is not added.
