A packaging apparatus comprising: a support frame; a packaging station having a first tool, a second tool, and one or more actuators, operably coupled to at least one of the first tool and the second tool, to modify a position of the second tool with respect to the first tool; and a control unit comprising at least one of: a digital processor with memory, an analogical type circuit, a combination of one or more digital processing units with one or more analogical processing circuits, the control unit being operably coupled to the one or more actuators, wherein the one or more actuators have: - a first configuration, in which the first tool and the second tool are spaced from one another by a first distance, wherein the first tool and the second tool are configured to form, in the first configuration, a substantially closed chamber, - a second configuration, in which the first tool and the second tool are spaced from one another by a second distance greater than the first distance, wherein the control unit is configured to operate in a first modality wherein the control unit is configured to: - move the one or more actuators from the first configuration into the second configuration, - maintain the one or more actuators in the second configuration for a first time interval, and - move the one or more actuators from the second configuration into the first configuration; characterized in that the one or more actuators have: - a third configuration, in which the first tool and the second tool are spaced from one another by a third distance greater than the second distance, wherein the third configuration is distinct from the second configuration, and in that the control unit is further configured to operate in a second modality wherein the control unit is configured to: - move the one or more actuators from the first configuration into the third configuration, - maintain the one or more actuators in the third configuration for a second time interval, and - move the one or more actuators from the third configuration into the first configuration. a support frame;
