Three in one go

You can save two stations with the new cosmetic seal upgrade for Herrmann's TSM, as the hermetic and cosmetic seal is sealed in just one station and does not require a cooling station.

New top seal solution from Herrmann combines three stations in one

It’s a space-saving and sustainable solution for sealing hermetic and cosmetic seals on stand-up pouches: with the COS upgrade for the top seal module TSM from Herrmann Ultraschall, manufacturers of packaging machines will be able to perform several work steps in just one sealing station.

Though they do not contribute to the security of the packaging, a cosmetic seal suggests an all-around securely packaged product and helps to create customer trust. For manufacturers, however, this means that in addition to the stations for hermetic sealing and cooling, they needed another station just to seal the cosmetic seal.

In order to save valuable space and costs in this process, a new function has been added to Herrmann's TSM top seal module. As a result, the module can now apply the hermetic and cosmetic seal in one station. A cooling station is not necessary because the packaging films only heat up in the sealing area inside the film. While manufacturers of packaging machines save valuable space in their line, their users benefit from a more compact machine as well as lower acquisition costs. Top seal modules that have already been installed can also be supplied with the new upgrade.

Although the hermetic and cosmetic seal are inserted in one station, this is still done in two consecutive steps. This makes it possible to optimize and monitor the quality of both of the processes separately. If there is an error in the sealing process, for example due to incorrect positions in the sealing station or due to folds in the head area, this is detected immediately and the rejection of the pack is signaled by the ultrasonic generator.

Defective seals caused by residual product in the sealing zone are prevented with the TSM, as the vibrations of the ultrasonics displace the product from the sealing area. Thanks to the constant monitoring of the sealing processes and the safe sealing, several tons of rejects can be saved every day, while at the same time increasing the shelf life of the food.

The top seal module from Herrmann is particularly suitable for sealing stand-up pouches and sachets – regardless of the temperature or the nature of the contents. Heat is generated only for a short time by friction inside the materials and does not have to be applied externally. As a result, even mono-materials can be sealed visually flawless despite their sensitive characteristics. In addition, there is no need to heat up the tools, which not only saves time but also up to 75 percent energy. As a result, the new TSM helps companies to achieve their sustainability goals while at the same time optimizing their packaging processes.
 

Sustainable and efficient sealing with the new TSM

Sealing eco-friendly materials securely with the Top Seal Module from Herrmann

Save energy and material permanently: with the TSM Top Seal Module Herrmann Ultraschall offers a simple solution for sealing packaging materials more efficiently and reliably. Thanks to the new solution for sealing the hermetic and cosmetic seal at the same time, companies can also reduce the size of their packaging machines.

When switching to environmentally friendly packaging materials, companies also have to change their processes as conventional joining methods often lead to damage to the sensitive materials. A particularly gentle method to seal mono-materials, paper-based packaging materials and more is ultrasonic sealing.

With the Top Seal Module (TSM) from Herrmann, heat is only generated for a short time by friction inside the materials when sealing stand-up pouches. Therefore, heat does not have to be conducted through the packaging material from the outside. This guarantees a perfect appearance even with single-layer films with the narrowest process windows and prevents burns with paper-based packaging materials.

At the same time, the module contributes to reducing reject rates. The vibrations of the ultrasonics ensure that product residues or contamination are removed from the sealing area and produce a tight seal. This reduction in waste not only saves costs and packaging material, but also improves the sustainability record and significantly reduces food wastage due to leaking packaging. In addition, the intelligent ultrasonic generator monitors each individual seal. If faults do occur, for example, due to incorrect layers or folds in the seal area, the removal of the package is initiated directly from the generator.

Energy consumption can also be significantly improved by switching to the TSM. Since the module seals without warm-up time and external heat, you can save up to 75 percent in energy with ultrasonic sealing - a major advantage in view of rising energy prices.

The TSM can be easily integrated into new or existing packaging lines for sealing stand-up pouches. The big advantage, thanks to the new COS upgrade, is the module can seal the hermetic and cosmetic seals in just one station. Therefore, packaging companies benefit from a more compact machine, more free space for additional stations in the filling machine, and lower purchasing costs.
