Doboy B-550M Validatable Band Sealer

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

The expanded heat sealing section permits higher speed operation.  This Doboy sealer still features compression (gusset) rollers standard!

Ideal for sealing bags of medical devices, surgical kits, bio-pharma products, garments, uniforms, chemicals, at medium to high speed.
