Top seal for stand-up pouches: 3 stations in 1

Herrmann Ultraschall has developed a sustainable and space-saving solution for the hermetic and cosmetic seals of stand-up pouches: with the COS upgrade of the top seal module (TSM), packaging machine manufacturers will be able to perform several work steps with just one station.

While not interfering with the airtightness of the package, a cosmetic seal conveys the idea of a securely packaged product, actually helping to build customer confidence. For manufacturers, however, this would mean acquiring an additional dedicated station in addition to those for hermetic sealing and cooling.

To save space and cost in this process, Herrmann has therefore added a new feature to the TSM module, which not only does both jobs in one station but also makes the cooling station superfluous, since the packaging films only heat up in the sealing area, inside the film itself.

While packaging machine manufacturers therefore save valuable space and components on the line, users benefit from a more compact and economical machine.

The new COS functionality can also be applied to already installed top seal modules with a simple upgrade.
