Carton flow is a form of shelving that uses a gravity feed rear load design. Each unit consists of one or more inclined runways. Merchandise is loaded in the rear of each runway. As an item is removed from the front, the item directly behind it slides forward in place of the previous.
Put simply, the main advantage of carton flow rack over static rack or shelving systems is that merchandise remains better organized and easier to find/pick. With carton flow rack, the product is automatically rotated on a first in first out basis. Merchandise is stocked in the rear of the carton flow rack and moves toward the picking station in front on an inclined shelf equipped with specially designed roller track. When a carton is removed from the picking station, the next one in line rolls to the front. Carton flow always keeps items within reach. Inventory is easier to monitor and control since products are fully visible at all times.
