A filler is a load securing material used to fill empty spaces on a pallet. The purpose of a filler is to prevent the load from shifting or tipping during transportation. Filling empty spaces on a pallet also allows for better utilization of trailer space and reduces the risk of damage to the goods being transported. Fillers can be made of various materials such as cardboard, foam, plastic, or air bags. They are chosen based on the weight and shape of the goods being transported, as well as the mode of transportation used. A properly filled pallet helps to ensure that the cargo reaches its destination safely and without damage.
