New sealing technology for the flowmodul
The latest model variant of the Flowmodul flow-wrapping component features an even more open machine layout, which further facilitates accessibility for maintenance and cleaning. Additionally, Schubert now offers an even more extensive selection of possible sealing technologies. This enables customers to choose the most suitable processes for their products. For example, Schubert has developed a new heat-sealing technology specifically for highly sensitive products. In the case of hot-seal films, the Flowmodul adapts seamlessly to the variable speeds of the upstream F44 robots, without this having an effect on the seal quality or the tightness of the flow-wrap bags. The patented flying transverse sealing unit used here is highly flexible and ensures that the sealing times remain constant. If hermetically sealed packages are required, the sealing time can be set accordingly.
The machine exhibited at PackExpo is equipped with this new, quickly-adjusted heat-sealing technology. The exhibit will package mixpacks with two different products – one biscuit each with white chocolate and one with brown chocolate. The machine achieves an output of 250 products or 125 flow-wrap bags per minute. Alternatively, the flow-wrapping machine can be provided with a non-rotating ultrasonic longitudinal sealing unit, which is especially suitable for films with high barrier effect. Both systems are characterised by low heat development, which makes them ideally suited for heat-sensitive products such as chocolate.
With the Flowmodul, Schubert offers a flow-wrapping component with which the packaging of products in flow-wrap bags can be fully integrated into the packaging machine manufacturer’s modular machine concept. Thanks to the uniform machine control of the TLM system and the flow-wrapping component, operation is user-friendly. The flow-wrapping component can be operated together with the entire line via a single HMI interface. The Flowmodul is supplemented by standard Schubert components such as the image recognition system, which ensures that only perfect products enter the feed chain. If the product needs to be placed in a carton or plastic tray, this function can be easily implemented with an additional sub-machine.
