A first end closure flap is folded into position over the entire opening and a band of adhesive is placed across each side of the first flap with the adhesive extending onto the adjacent flaps which are then folded inwardly to create a sealed end with a fourth flap folded on top of the first folded flaps. A third band of adhesive may be used to hold the fourth flap in position and provide additional sealing qualities.
