Four Types of Case & Tray Packers

Horizontal load, top load, bottom load and tray packing are four types of case and tray packers built at Douglas. Within these four types are multiple styles of case and tray packers designed to provide packaging solutions for a variety of applications. Each style of case and tray packer offers different advantages that can solve unique packaging automation opportunities. At Douglas Machine, we create custom-built case and tray packers for a wide range of market segments. Although no two packers are exactly the same, the machines we produce belong to broad groupings. Whether you are in need of a packer to increase production, or your old packer is in desperate need of replacement, we can design the perfect packer for your application. This post will provide you with an overview of the types of case and tray packers that we build here at Douglas.

1. Horizontal Load
