Continuous Motion Sealbar Machine

Polypack’s CMS series machines are inline shrink wrappers running in continuous motion, designed to provide a bullseye wrap to products longer than 4 inches. These machines have belt-to-belt transfers, controlled by motor inverters for positive transfers. The CMS series shrink bundling machine can be installed at the end of atray multipacker to shrink wrap each tray after they are formed and loaded.

POLYPACK’S CMS SERIES machines are available as stand-alone systems that can either be handloaded or fed by an existing conveyor. The CMS series machines are also available with a wide array of product collation modules as well as a pad feeder to create pad-supported shrink multipacks.
