Evacuation

The process of drawing the air out of the pack to create a vacuum. It is the basis of vacuum packaging and, with MAP, takes place before the protective gas is added. On thermoforming packaging machines it is done by edge evacuation or with a narrow top film, while tabletop chamber machines reach up to 99.8 % vacuum.
