A packaging process comprising: providing an evacuation station having a first chamber, a second chamber, and a dividing wall, the dividing wall separating the first chamber from the second chamber and having a gap fluidly connecting the first chamber and the second chamber, the second chamber being fluidly connected to a vacuum source (110, 112, 116) configured to apply a controlled vacuum pressure to the second chamber, the evacuation station being provided with a control unit configured to control the vacuum source (110, 112, 116); providing a package containing a product to be packaged, the package being made from a film and having an open end; arranging the package in the evacuation station such that: - a terminal portion of the open end is positioned within the second chamber, - a non-terminal portion of the open end and the product are positioned within the first chamber, and - an intermediate portion of the open end passes through the gap, the intermediate portion extending between the terminal portion and the non-terminal portion of the open end, the open end putting an inner volume of the package in fluid communication with an inner volume of the second chamber; controlling, by the control unit, a pressure differential between a first internal pressure in the first chamber and a second internal pressure in the second chamber to cause aspiration of gas from the inner volume of the package, characterized in that the step of controlling the pressure differential comprises increasing the pressure differential, the step of increasing the pressure differential including decreasing the size of the gap; or the step of controlling the pressure differential comprises decreasing the pressure differential, the step of decreasing the pressure differential including increasing the size of the gap. providing an evacuation station having a first chamber, a second chamber, and a dividing wall, the dividing wall separating the first chamber from the second chamber and having a gap fluidly connecting the first chamber and the second chamber, the second chamber being fluidly connected to a vacuum source (110, 112, 116) configured to apply a controlled vacuum pressure to the second chamber, the evacuation station being provided with a control unit configured to control the vacuum source (110, 112, 116); providing a package containing a product to be packaged, the package being made from a film and having an open end; arranging the package in the evacuation station such that: - a terminal portion of the open end is positioned within the second chamber, - a non-terminal portion of the open end and the product are positioned within the first chamber, and - an intermediate portion of the open end passes through the gap, the intermediate portion extending between the terminal portion and the non-terminal portion of the open end, the open end putting an inner volume of the package in fluid communication with an inner volume of the second chamber; - a terminal portion of the open end is positioned within the second chamber, - a non-terminal portion of the open end and the product are positioned within the first chamber, and - an intermediate portion of the open end passes through the gap, the intermediate portion extending between the terminal portion and the non-terminal portion of the open end, the open end putting an inner volume of the package in fluid communication with an inner volume of the second chamber; controlling, by the control unit, a pressure differential between a first internal pressure in the first chamber and a second internal pressure in the second chamber to cause aspiration of gas from the inner volume of the package, characterized in that
