ABSTRACT:
A bag for containing a flowable product comprises a plurality of panels hingedly coupled along fold lines, an opening at one end of the bag, and a flap hingedly coupled to one panel along a fold line for overlapping an opposite panel and closing the opening. An adhesive layer extends across the entire width of the flap to seal the flap to the opposite panel which is provided with an adhesive coating comprising kaolin clay, to facilitate opening of the bag, but which provides sufficient bond strength during shipment and handling to preclude inadvertent opening of the bag.
