Corrugated Squaring Bundler CB4000SQ
The highest quality palletizing and unitizing equipment at the lowest cost of ownership



Polychem’s lumber press secures loads of lumber, plywood, O.S.B., M.D.F, and particle board with our AAR approved 5/8" polyester strap to improve production efficiency and reduce cost. Our ruggedly designed system can be outfitted with automatic dual or magazine bunk feeders to increase production throughput. In addition, our system can be outfitted with automatic top and bottom edge protection to prevent strap indentation or damage to your lumber and panel products. Polychem’s PLTS is equipped with a high speed TR19HT strapping head which heat seals our polyester for safe and consistent joint efficiency. Our AAR approved strap is available in standard or jumbo coils to increase production uptime. Additional options include semi-automatic press operation with tool and balancer, tank heater for cold weather operation, and additional entry and discharge conveyor.
