In addition to the developments for the rapidly evolving circular economy, Br\u00fcckner Maschinenbau is also sticking to its ambitious targets for further increasing efficiency in film production. From the company's point of view, this means reducing the use of raw materials, ever decreasing energy consumption and \u201ezero waste\u201c in film production.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The more efficient and high-output a film stretching line is, the lower the specific energy consumption. These parameters can mainly be influenced by the line speed and the line width: In the production of the two packaging films BOPP and BOPET, the benchmark in production speed has so far been around 600 metres per minute. To the K 2022<\/a> becomes Br\u00fcckner Mechanical Engineering<\/a> New system concepts with significantly higher running speeds<\/strong> introduce.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

BO films made of polyamide are particularly suitable for packaging oily, fatty foods and frozen foods. The need for this is constantly increasing and with it the demand for corresponding film stretching systems. Presented are New system types based on an increase in production speed from 220 to 350 metres per minute<\/strong> and a system extension from 6.6 to 7.4 metres with up to 80 percent more power.<\/p>

In the battery separator film and capacitor film segments, the previous (already exclusive) system width of 5.5 metres will be gradually increased to more than 6.0 metres and the associated Performance increases of over 20 per cent<\/strong>. In addition, both the sequential and simultaneous stretching technology for capacitor films<\/strong> further developed: The focus was on higher film yields and optimised film properties, particularly for films in the 2-\u00b5m range.<\/p>

Thanks to a new type of \u201edirect fluff dosing\u201c, the edge trimmings and waste generated during production can be fed directly back into the extrusion process in a higher percentage without a prior regranulation process.<\/p>
