Extrusion International 6-2019

PREVIEW 64 Extrusion International 6/2019 At Interplastica 2020 in Moscow Brückner presents new solutions re- garding plastics and environment, recycling and circular economy. Rus- sian, CIS and Eastern Europe’s plas- tics film producers can look forward to various solutions directly from Brückner’s unique R&D center: Mono-materials: Brückner Maschi- nenbau is working on a means to make films with the highest possible recycling capabilities producible on film stretching lines. The focus is on mono-material polyolefin film struc- tures made of BOPP or BOPE with superior mechanical, optical or bar- rier properties, which will be able to for innovative BOPE films is only now starting to develop, film producers will be able to react swiftly and flex- ibly to market trends: The new lines also have the flexibility to produce BOPP films. 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 ex- tended range of films. Line concepts for recyclable shrink films: Polyolefin shrink films are the trend for a better sortability and re- cyclability of bottles and sleeve la- bels. Brückner Maschinenbau has de- veloped special low-density sleeves, fulfilling exactly this, and offers dedi- cated stretching line concepts. For low, medium and high shrink films made of PETG, PLA, PS, PVC or even a combination Brückner offers highly efficient lines. New inline coater: Even if recycling stands at the forefront of a circular economy, new mono-material struc- tures must fulfil the highest demands and must not be inferior to previous packaging 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 allows the production of extremely thin functional layers within the nano-range. Due to the extreme thinness, the layers don’t disrupt the sorting and recycling, but cater, for example, for an improved Biax Film Production for a Circular Economy 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 optimal recycling. One example: Ultra-high barrier BOPP films with a super-thin EVOH coating – allowing packaging laminate simplification and reducing the number of further converting steps. Hybrid line concepts: Combina- tion of BOPE and BOPP production: Brückner will introduce two com- pletely new line concepts for the pro- duction of BOPE films (biaxially ori- ented polyethylene).
