Doboy S-CH-S High-speed Continuous Band Sealer

The S-CH-S is a high-speed, industrial, continuous band sealer designed for sealing polyethylene, foil laminates, Poly/Tyvek pouches, paper laminates, and almost any heat sealable material!

The S-CH-S band sealer is engineered for use in the most demanding applications where thick bag material and high-speed operation are essential.

It excels at running thick, side-gusset bags at very high speed and is most often used as an integral part of an automatic bagging system.
