We believe our DP-4 is the most heavy-duty drop packer in the industry. If you have a heavy payload, this is the packaging machine for you. We are the only company that uses a solid aluminum casting for the case elevator instead of a weldment. Climax Packaging Machinery has drop packers in the field that are still running after 30 years of continuous service. If you want reliability and durability, the DP-4 drop packer is the machine for you.
