B-550 Industrial Band Sealer (Retired Demo Unit)

BaggingGuys is currently offering this 2016 Bosch Doboy B-550 Industrial, Continuous Band Bag Sealer.  It was built in 2016 and utilized for a customer demonstration in a bakery environment for less than 1,000 production hours.  Since that demo, it's been kept at the Doboy factory and only utilized for Bosch demonstration and seal testing purposes!

This B-550 is a (RIGHT-to-LEFT feed) industrial-grade, 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!

This Doboy B-550 was made in the USA and ships from New Richmond, WI.

Recently replaced by the all-new, Syntegon Doboy CBS-D-750 sealer, this Model B-550 is ideal for sealing bags of dry food, fresh food, produce, snack mixes, tortillas, flat bread, candy, bakery mixes, single-serve bakery products, Mil-spec packages, pastry bags, IQF products, shredded cheese, shredded tobacco, garments, uniforms, chemicals, etc. at medium to high speed.
