1. A longitudinal sealer comprising:
a housing configured to be installed in a foam-in-bag system,
an arm movably coupled to the housing; and
a heating element having a leading edge exposed through an exterior surface of the arm;
wherein a position of the arm with respect to the housing is controllable so that the arm is movable between a first location where the leading edge of the heating element is not in contact with a film in a film path of the foam-in-bag system and a second location where the leading edge of the heating element is in contact with the film in the film path of the foam-in-bag system;
wherein, when the housing is installed in the foam-in-bag system, the longitudinal sealer is configured to be communicatively coupled to a controller of the foam-in-bag system;
wherein the controller is configured to control the position of the arm with respect to the housing;
wherein the foam-in-bag system includes an actuator configured to engage the longitudinal sealer to move the arm, and wherein the controller is configured to control the position of the arm with respect to the housing by controlling the actuator; and
wherein the actuator is configured to engage a plunger of the longitudinal sealer and wherein the plunger is configured to contact the arm to cause the arm to rotate in a first rotational direction.
