According to a press release Brückner Maschinenbau 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 film with superior mechanical 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 optimal recycling.

For the K 2019 Brückner will introduce two completely new line concepts 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-barrier uses alongside conventional packaging film. As the demand for innovative BOPE films is only now starting to develop, film producers will be able to react swiftly and flexibly to market trends.

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 production of extremely thin functional layers 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 excellent barriers in combination with the equally thin but effective aluminium oxide coating.
