Abstract
A combined box and resealable bag includes a paperboard box having a front wall, a rear wall, a pair of opposed side walls and a plurality of flaps capable of forming a bottom wall. The box walls have upper ends and lower ends, inside surfaces and outside surfaces. The upper end of each of the box walls is folded outwardly and downwardly so that the inside surface of each of the upper ends forms a strip that faces outwardly. The inside surfaces of the box walls, including the outwardly facing strips, have a thermal plastic coating thereon. The combination also includes a bag made of flexible plastic material having a zippered top and downwardly extending front and rear bag walls. While the box is still in its flat blank condition, the lower edge portion of the bag walls are heat sealed to the outwardly facing strips on the box blank. Thereafter, the front, rear and side walls of the box blank are expanded to form a box.
