Abstract
Sealed carton closure and method for making same particularly adapted for paperboard cartons having inwardly foldable flaps where the carton is designed to contain material which is subject to sifting or leaking out of the carton. 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.
