Palletizer machines handle the job for you, efficiently forming layers of loose jars, bundles, boxes, and cans (depending on the model chosen).  These machines are built to adapt to your specific needs.  The picking head can be customized with magnetic grippers for flat layers, standard grippers for bundles, or even a comb attachment for delicate items.  For added flexibility, the system can be configured for top or bottom product feeding, and operation can be automatic or robotic.  Ultimately, the best palletizer solution depends on your priorities: how many products you need to stack per hour (productivity), how easily you need to switch between different product types (flexibility), and how the machine fits into your existing production line layout.
