Marathon's new Foam Baler is a horizontal baler specially designed to handle the unique characteristics of polyfoam products. Foam fabricators experience labor savings by generating bales twice the density of a typical vertical baler. In addition, the Foam Baler can be conveyor or cart fed for further automation and cost savings.
  • The powerful compaction process means less air and bales of foam that weigh more than 1300 pounds!
  • The simple "spring back control chamber" provides space for the foam to expand to prevent obstruction of the feed chamber while loading.
  • Bales are tied in the short direction which also aids in bale density and integrity.
