Brückner Maschinenbau, the marketer for film stretching lines, is a member of the Brückner Group, Germany, a worldwide leading supplier of tailor-made engineering solutions and services for the plastics and packaging industry, with more than 2,400 employees. Other members of the group include Brückner Servtec, offering service & upgrading solutions for film stretching lines, Kiefel, specializing in machines for forming and joining plastic materials for a variety of industries, and PackSys Global, one of the world’s leading packaging equipment manufacturers.
Brückner Maschinenbau has developed mono-material packaging solutions with the highest possible recycling capabilities. So, the life cycle of plastic packaging can be closed, as requested by brand owners and legislation. The state-of-the-art materials BOPP and BOPET have a great potential for high-value second life products in an upcoming circular economy. A new opportunity is opening up with BOPE. Mono-material polyolefin film structures made of BOPP or BOPE with superior mechanical, optical, or barrier properties will be able to supplement multi-layer films made from different materials. These are ideal for use in new, single-origin packaging and guarantee good portability 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.
Brückner introduces two completely new line concepts for the production of BOPE films. 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: The new lines also have the flexibility to produce BOPP films. Film producers can choose 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.
Even if recycling stands at the forefront of a circular economy, new mono-material structures must fulfill 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 adherence during metallizing and excellent barriers in combination with the equally thin but effective aluminum oxide coating.
At the joint Brückner Group booth, besides Brückner Maschinenbau and Brückner Servtec, Kiefel will be showing the latest developments for the packaging, medical and appliance industry.
