A container such as a Regular Slotted Carton (RSC) with side handles provides an improved alternative to other containers for packing, storing, stacking, displaying, handling and shipping a dense, free-flowing material such as granular clay. An integrated handle places the load of carrying the container over the full width of the hand and fingers. A cavity is created that allows the user's hand or fingers to be easily placed into the handle and prohibits the liner of the container from interfering with placement of the hand or fingers. A pour spout is also provided in the container that allows for access to the liner. The pour spout may be formed by tearing off a perforated portion of the container. A pinch closure may be provided so that the portion of the liner pulled through the spout can be secured.
