DESCRIZIONE
A packaging process and a packaging apparatus are provided. The packaging process comprises the steps of directing towards a semi-sealed package containing a product (20) to be packaged a flow of gas (17) and creating relative motion between the outlet (16) of the gas flow and the semi-sealed package such that the flow of gas passes the semi-sealed package, thereby compressing it and expelling gas present within the package. The packaging apparatus comprises a gas blower (13) , an outlet (16) coupled to the gas blower (13), and a means for moving the semi-sealed package (30). The means for moving (30) are configured to move the semi-sealed package, thereby creating relative motion between the outlet (16) and the semi-sealed package such that the flow of gas (17) passes the semi-sealed package, thereby compressing and expelling gas present within the semi-sealed package. The apparatus can further comprise a housing (11), for example in the shape of a tunnel. Further, the housing can be arranged in a fixed position with respect to the operating region. In particular, the housing can be configured to contact the means for moving (30) in a substantially sealed manner or it can have a tubular shape configured to encompass the means for moving (30).
