Abstract: A method and system for packaging products in a container employs an active compression assembly having pressure members which are shifted from a raised position to a lowered operational position. In the operational position, each pressure member holds a respective upper container flap against a lower container flap while an interposed adhesive sets. More specifically, with the at least one pressure member pushing upon the upper flaps, both the container and the at least one pressure member are forced to move in unison along a manufacturing line while the at least one pressure member applies pressure on the upper flaps as the adhesive sets to seal the upper flaps to the lower flaps and close the upper opening.
