The disclosure relates to a pack for articles of food or other merchandise comprising a bag (30) and a carton form (40) for supporting a lower part of the bag having a base (41) with a central fold line (32) and walls (43) hinged to the base along further fold lines (44) to enable the carton and bag to be folded flat and to be erected to open the bag. The side walls of the lower part of the bag are secured to the side walls of the carton so that when the carton is erected by opening the folded base into a V-form, the bottom part of the bag is opened, and, as the V-form is progressively widened, the bag is tensioned by the walls moving apart until the base of the carton moves "over center" and inverts to brace the lower part of the bag open to receive an article or articles to be packed therein.
