That is why Brückner Maschinenbau is sticking to its ambitious goals for fur- ther increasing efficiency in film produc- tion in addition to the developments for the rapidly developing circular economy. This means decreasing raw material use, ever lower energy consumption and "zero waste" in film production. Faster and wider BO plants The more efficient and higher output a film stretching line is, the lower the spe- cific energy consumption. These parame- ters can mainly be influenced by the line speed and the line width. BOPP and BOPET : In the production of the two most popular packaging films, BOPP and BOPET, the benchmark in pro- duction speed has so far been around 600m/min. At K 2022, Brückner Maschi- nenbau will present new line concepts with significantly higher running speeds. BOPA : BO films made of polyamide are particularly suitable for packaging oily, fatty foods and for frozen foods. The de- mand for this is continuously increasing and with it the demand for corresponding film stretching lines. At K, Brückner Maschinenbau will present new line types with up to 80% more out- put – based on an increase in production speed from 220m/min to 350m/min and a line widening from 6.6m to 7.4m. Battery separator foils and capacitor foils: In these segments, the previous (already exclusive) line width of 5.5m is being in- creased step by step to over 6m and the associated increase in output of over 20%. In addition, both the sequential and the simultaneous stretching techno- logy for capacitor films were further de- veloped: the focus was on higher film yield and optimised film properties, espe- cially for films in the 2 µm range. Technical innovations for more sustai- nability in film production Direct recycling: Thanks to a new type of "direct fluff Ddosing", the edge trim- mings and waste produced during pro- duction can be directly fed back into the extrusion process in a higher percentage – without any prior re-granulation pro- cess. This saves energy, conserves raw material and comes very close to the goal of "zero waste" in production. Intelligent stretching oven management: Instead of the heat exchangers previously used for heat recovery, a patented, energy-efficient oven control system across all temperature zones of the stret- ching oven now ensures an energy saving of around 200 kW per year. Aerodynamic zone separation The patented process guarantees even better and more uniform film quality across the entire working width and for ever higher production speeds. This in- creases the proportion of A-grade film on the winder, reduces production waste and lowers specific energy consumption.  生产线改造包BOPP–ILC（在 线涂层）可在现有BOPP生产线上生产 可回收超高阻隔膜（UHB）。创新的在 线涂层（ILC）技术是在薄膜生产过程 中直接对塑料薄膜进行湿化学涂层（水 基）。在MD和TD方向之间执行该步 骤。纳米级涂层增强了进一步的加工步 骤，如金属镀，显著减少了异物含量的 使用，从而允许根据欧盟指令94/62/EC 生产可回收薄膜。  新的BOPP–PE生产线改造包 通过LLDPE或HDPE的选择扩展了所有 BOPP薄 膜 拉 伸 生 产 线 的 产 品 组 合。BOPE薄膜具有非常好的机械性 能，允许仅在一半厚度上替换PE吹塑薄 膜，从而实现完全可回收的单材料结 构。必要的改进步骤，通常在挤出、流 延单元和MDO区域，根据现场生产线和 n 在今年的K展会上，布鲁克纳服务 技术（Brückner Servtec）将展示新的 定制转换包（生产线改造包），通过转 换现有薄膜拉伸生产线上的薄膜类型支 持循环经济、降低能耗和提高生产工艺 质量的新解决方案，进一步增加了薄膜 生产的可持续性。此外，将展示已建立 的Brückner ONE数字服务平台的新功 能，这将大大方便薄膜拉伸线的维护和 操作。 布鲁克纳服务技术的新生产线改造 包旨在将现有的薄膜拉伸生产线转换为 可持续生产可回收的单材料薄膜类型， 如BOPP、BOPLA或BOPE。必要转换 措施适用于各类生产线，适用于任何时 期的生产线。与生产线运营商一起，对 工厂进行现场评估，并由此确定转换的 具体要求。 薄膜拉伸线可持续性发展的智能解决方案 情况进行各别调整。 混合式机器设计优化了高产量，为 操作员提供了有利于继续以全产量生产 BOPP和BOPE薄膜的选择。  BOPET–PLA生产线改造包， 允许生产这种生物基的原料。BOPLA薄 膜具有优异的透湿性能，具有较高的自 然表面张力，可工业上堆肥降解。转换 包将挤塑和原料进料领域的所有必要调 整与生产高质量和高产量PLA薄膜所必 要的工艺技术相结合。 Brückner ONE数字服务产品已在 2019年K展会上向全球公众展示，自此 以来，已安装在全球350多条生产线 上，占可连接资产的近50%。客户受益 于全球可用的在线服务模块、备件管 理、轻松通信和高级在线文档。所有数 据均是通过TÜV Nord体系认证的最高数 48 2022 Extrusion Asia Edition 2/2022
