    摘要： A packaging apparatus comprising: a packaging assembly (8) configured for receiving at least one support (4) and for tightly fixing a film (18) to the support (4), the packaging assembly (8) including a lower tool (22) and an upper tool (21); an inner heater (200) carried by the upper tool (21) and having a heating surface (201) configured to heat at least a part of a film portion (18a); a peripheral heater (202) carried by the upper tool (21) and positioned radially outside with respect to the inner heater (200), the peripheral heater (202) having a heating surface (203) configured to heat seal to the at least one support (4) at least a peripheral region of said film portion (18a); a supply unit (300) configured to control energy supplied to said peripheral heater (202) and to said inner heater (200); and a control device (100) acting on the supply unit (300) and configured for commanding the supply unit (300) and control a supply of energy to the peripheral heater (202) independently from a supply of energy to the inner heater (200). Use of the apparatus and process using the apparatus are also disclosed.

    摘要： A device (1) for evacuating gas from a package (50) in a packaging apparatus, the package (50) having an open end (55), the open end (55) having a terminal portion (54), a non-terminal portion (52), and an intermediate portion (53) located between the terminal portion (54) and the non-terminal portion (52) of the open end (55), the device (1) comprising a vacuum chamber (10) having an elongated opening (14) extending along a longitudinal axis of the vacuum chamber (10), an evacuation means configured for providing the vacuum chamber (10) with an internal vacuum pressure that is lower than an ambient pressure outside the vacuum chamber (10), means for moving (30) a package (50) relative to the vacuum chamber (10), and a control unit (60) programmed for controlling the means for moving (30) to relatively move a package (50) to be evacuated with respect to the vacuum chamber (10) and activating the evacuation means to provide the vacuum chamber (10) with the internal vacuum pressure; the package (50) to be evacuated is positioned so that, during the relative movement of the package (50) with respect to the vacuum chamber (10), a terminal portion (54) of the open end (55) of the package (50) relatively moves within the vacuum chamber (10) and a non-terminal portion (52) of the open end (55) relatively moves outside the vacuum chamber (10), an intermediate portion (53) of the open end (55) passing through and relatively moving along the opening (14). The vacuum chamber (10) comprises a first sub-chamber (10-1, 10-2, 10-3) and a second sub-chamber (10-1, 10-2, 10-3), and the control unit is further programmed to provide the first sub-chamber (10-1, 10-2, 10-3) with a first pressure and to provide the second sub-chamber (10-1, 10-2, 10-3) with a second pressure different from the first pressure. A packaging process using the gas evacuation device and a packaging apparatus including the device are also disclosed.
