Gas Flushing (Basic)

The “gas flushing” option for a VFFS machine is a feature that helps to flush out oxygen from the package before sealing it. This option is particularly useful for packaging products that require an oxygen-free environment, such as fresh foods, or for packaging products that need to have a long shelf life.

A VFFS machine with the gas flushing option typically includes a gas supply system that injects an inert gas, such as nitrogen or carbon dioxide, into the package before it is sealed. This process removes oxygen from the package, creating a modified atmosphere inside the package that can help extend the shelf life of the product and prevent spoilage.
