Thiele traces its history back to 1931 when the first Deltaseal bag sealing machine was completed and sold by a special branch of the Bemis Company that would later become Bemis Packaging Machinery Company (BPMC). In the late 1940's that branch was established as a separate business unit of the Bemis Company and was moved into the building at its current location in northeast Minneapolis.
At about that same time (1949) Thiele Engineering Company was established by Ed Thiele. A short time later, from a facility in Hopkins, MN the company manufactured its first reciprocating placer for promotional coupons.
During the decades that followed, both companies grew and flourished, expanding their product lines through acquisitions and development. Thiele Engineering eventually moved to Minneapolis and in 1995 the firm was acquired by Barry-Wehmiller. Later in 1995, Barry-Wehmiller also acquired Frontier Equipment of Fergus Falls, Minnesota, combining the two companies into a single entity but retaining both locations and manufacturing operations. The Bemis Packaging Machinery Company was acquired by Barry-Wehmiller in 1997.
In 2018, brands under the Thiele Technologies banner became part of BW Flexible Systems and BW Integrated Systems.
Thiele provides advanced high-speed packaging and converting automation solutions worldwide to a variety of industries including fresh and frozen food, dairy, bakery, pet food, beverage, horticultural, paper goods, pharmaceutical, medical devices, cosmetics, commercial printing, contract packaging, mailing and fulfillment and petro chemicals.
