Two ongoing trends have been causing headaches for warehouses utilizing bulk storage or drive-in racking – the first is the move to lighter packaging, and the second relates to ever increasing product types (SKU) with smaller and smaller lot sizes.
With lighter packaging, products that were once able to be stacked 3 or 4 high may now only be able to be stacked two high, or not stacked at all. Facilities that have large sections of bulk storage are finding their height utilization severely restricted, and may end up storing half of what they used to store in a given area.
