The Bosch Doboy B-550 is an industrial, continuous band sealer designed for sealing heat sealable materials including polyethylene, foil laminates, Poly / Tyvek pouches, paper laminates, and almost any other heat sealable bag or material!

The B-550 is made in the USA and is a hybrid version of its popular and proven predecessor - the Doboy B-500 - and its big brother, the Doboy CBS-D.
