Syntegon Technology, formerly Bosch Packaging Technology, will showcase two innovations at interpack 2020, including its “paper-ON-form” upgrade kit for horizontal flow wrapping machines to form cold-sealable barrier paper, in Düsseldorf, Germany, May 7-13.
The solution was engineered in the company’s development center in Beringen, Switzerland, and consists of a patented flow-wrap forming unit and sealing jaws for paper cold-sealing applications. The new kit is already being used on lines from international manufacturers for packaging chocolate bars in paper.
Syntegon Technology will also present an extended stroke length for Amplified Heat Sealing (AHS) applications on new horizontal flow wrappers. The innovation helps to optimize the thermal heat input and enables faster processing of mono-materials. “Sustainable paper and mono-material packaging are trending. As an innovation leader, we act in a future-oriented, sustainable way. Our upgrade kit allows customers to transition to sustainable packaging materials like cold-sealable paper on their existing horizontal flow wrapping machines – without any restrictions regarding speed or format,” said Christoph Langohr, project manager of sustainability horizontal packaging at Syntegon Technology.
The patented forming unit shapes paper without creasing or tearing it, and the customized cold sealing jaws gently create the sealing seams. At interpack, the new product will be presented as part of the Sigpack HRM bar-wrapping line and the Syntegon Pack Series flow wrappers. “Comprehensive tests and first field applications have repeatedly demonstrated that there are no restrictions regarding output rates, thus proving that paper flow wrapping easily matches the performance and usability of conventional flow wrapping,” Langohr added.
“The ‘paper-ON-form’ upgrade kit can be used for different types of paper as well as for conventional packaging materials, which makes it possible to gradually switch to paper,” Langohr further explained. The forming unit and sealing jaws are pre-configured by the Syntegon Technology experts based on the desired pack size and the material characteristics before being installed on existing Syntegon Technology machines, such as the Sigpack or Pack Series flow wrappers.
Amplified Heat Sealing with Extended Stroke Length
Amplified Heat Sealing (AHS) technology with linear drive was first introduced in 2017. By superimposing the rotational movement of the sealing tools on the linear movement of the transverse sealing station, the heat input into the packaging material can be increased, which allows for an optimal sealing quality. At interpack 2020, Syntegon Technology will unveil the new AHS. Since mono-materials often consist of a more temperature-sensitive outer layer than composite films, it can easily lead to faulty sealing seams. The AHS technology ensures an accurate heat input, which makes it easier to process delicate mono-materials for products such as cookies and crackers.
