A plastic bag is fastened to the inside of a carton blank at the time of manufacture so the bag becomes a part of the carton, i.e., the bag opens up at the same time the carton is set up from a flat, or knock down configuration. After the contents are loaded into the carton/bag unit, the flaps close the bag extensions over the open end and fold and seal the bag as the box flaps are closed. The operation can be manual or automatically performed as shown in the drawings.
