What is vacuum packaging?

Vacuum packaging means evacuating the air out of certain area. In food industry, this way of packaging means removing the air out of the product packaging right before sealing. This method can be manual and automatic. Vacuum bags are used in the manual method, and vacuum film is used in the automatic method.

There are multiple ways of separating vacuum film:
