Palletizers are used for load formation. They can be in the form of bag or cartons, they are called bag palletizer or carton palletizer. It increases productivity with high or low infeed bag palletizers or high or low infeed bag palletizer systems. These palletizers allow moving industry materials from one place to another. It allows lifting, transporting and rotating the industry material. They address the risk of manually lifting and lowering materials.

Palletizers and palletizers systems are machines that arrange products on a pallet for shipping, storing and moving. Palletizers have a feed area that receives the goods that are to be palletized. The feed area can be at ground level (low level) or at high level through a hopper overhead. While low level palletizers are fed from the ground level, products are fed to high level palletizers from an overhead hopper. The feed is received in a rolling or flowing fashion, in both cases, and is continuously transferred to the pallets, allowing for greater speed. Palletizers without feeds are usually robotic. In this case, the arm individually picks up, orients and places the individual item on the pallet. These robotic palletizers are often used with products that are fragile or heavy. The use of palletizers in these situations reduces the risk of injury to the workers and damage to the product.
