The packaging system uses a package forming tube fed from a film or spool and has a grip unit for closing the base of the formed sack. A quantity of the material to be packaged enters a cylindrical reception pipe (6) which is positioned inside the forming tube (13). The pipe (6) is independent of the tube (13). At least two tubes (5,15) are placed inside the reception pipe (6) and are independently connected to an exterior vacuum pump (10). One of the tubes (5) is porous and is used to de-aerate the product contained in the reception tube. |
