The focus is on mono-material film with superior mecha- nical and optical properties, which will be able to substitute previous multi-layer films made from different materials. These are ideal for the use in new, single- origin packaging and guarantee good sortibility in waste separation and opti- mal recycling. Combination of BOPE and BOPP pro- duction : For the K 2019 Brückner will introduce two completely new line con- cepts for the production of BOPE films (biaxially oriented polyethylene). Film producers can chose between a working width of 6.6 m and an output of 3 t/h, or a working width of 8.7 m and an output of 5 t/h. These are 5 layer concepts for an extended range of films. The new lines also have the flexibility to produce BOPP films: Specialities such as UHB films and coated films for high-bar- rier uses alongside conventional packag- ing film. As the demand for innovative BOPE films is only now starting to deve- lop, film producers will be able to react swiftly and flexibly to market trends. New inline coater : Even if recycling stands at the forefront of a circular eco- nomy, new mono-material structures must fulfil the highest demands and must not be inferior to previous packag- ing films. This is why Brückner has developed a new inline coater for all BOPP and BOPE lines, installed in the line before the transversal stretching, it makes the pro- duction of extremely thin functional lay- ers within the nano-range possible. Due to the extreme thinness, the layers don’t disrupt the sorting and recycling, but cater, for example, for an improved adherence during metallising and excel- lent barriers in combination with the equally thin but effective aluminium oxide coating. The focus remains on raw material and energy saving : Despite all develop- ments for the rapidly developing circular economy, Brückner Maschinenbau is keeping to its own ambitious objectives for a decreasing raw material usage and an increasingly minimal energy con- sumption during film production. Des- pite all legitimate demands about recy- cling and reusability, the challenge of cli- mate change and the reduction of the carbon footprint throughout the entire packaging production chain must not be forgotten. In the fight against climate change, we will still need plastic packag- ing that is produced in a resource-saving way. Speciality film lines : Alongside stretch- ing lines for the production of packaging films, machines for speciality films are becoming more important in Brückner’s portfolio. The company will be present- ing various innovations for the K 2019: • New high-temperature concept for BOPP capacitor film – this is interesting, for example, for the use in electrical components installed near motors • Lines for the production of stone pa- per based on BOPP or BOPE with a calci- um carbonate proportion of over 60%: not only with good printability and wa- terproof, but also environmentally friendly in production • Biaxially oriented polyester films (BO- PET) for optical applications. Brückner’s new, patent pending Relax System en- sures homogenous film properties and thus high film quality and better proces- sability • BOPI (biaxially oriented polyimide) is perfect for flexible optical applications, e.g. flexible displays. The stretching ovens and systems need to be suitable for very high temperatures of up to 400°C, is in Brückner’s new line con- cepts. Battery separator films: New techno- logies for growing markets : In the field of battery separator film for lithium-ion batteries, Brückner Maschi- nenbau has made a good name for itself in the market with leading film manufac- turers thanks to its successfully running lines.
