HST Packaging Machines is a key division of Häußler & Sauter in Kressbronn on Lake Constance.

For over 70 years, our engineering department, supported by a highly skilled team, has been developing and manufacturing high-performance packaging machines across various series, with a particular focus on tea bag machines. Thanks to our close links with our own packaging facilities and decades of experience with hundreds of packaging machines, our product development is problem-oriented and closely aligned with market needs. This approach has proved so successful that HST machines have been used successfully by many tea packers worldwide for decades.
