Technology to increase production of value-added oriented films
Brückner Maschinenbau, one of the market-leaders in film stretching lines, presented its latest technologies at Feiplastic 2015 in Sao Paulo, Brazil, earlier this month.
The German company helps Latin America's film producers to manufacture a variety of functional plastic films. It displayed line concepts for multilayer film applications with dedicated functional layers for cost-optimised film production. In its own technology center, Brückner has developed several promising new multi- layer film types and has implemented this expertise in its film stretching line technology, such as for high-barrier BOPP films in five, seven or nine layers.
To meet the fast-growing demand for a wide variety of thin-gauge BOPET packaging films, Brückner presented its range of shrink films for trendy labels and full body sleeves or tamper-evident packaging, which offer enormous potential and two-digit growth rates.
The company also focussed on special lines for the production of technical films for photovoltaic applications, screens of all kind made of BOPET optical film grades, high quality capacitor films made of oriented PP, PET or PVDF, printed electronics, membranes, high temperature films, thermal transfer printing ribbons (TTR films) and battery separator film. In all lines, Brückner Maschinenbau continues to optimise the possibilities for
energy savings and thus to reduce CO2 emissions. The measures presented at Feiplastic included low energy twin screw and single screw extrusion systems, a TDO heat recovery system, regenerating energy for line drive systems and an energy monitor for measuring and analysing the consumption of the film production process. Additionally, Brückner provides more solutions for a sustainable film production. This includes complete new lines, as well as modifying existing lines for bio-plastics processing, down gauging of films to reduce raw materials used or the development of an ultra-high barrier.
Brückner's technology centre enables
comprehensive research and development for all kinds of film stretching technologies under one roof. Feiplastic visitors had access to the latest information about several extensions, such as inline coating, enhanced in-line measuring technology, the new second laboratory line and Brückner's ‘Innovation Test Centre’ for verifying and validating new equipment developments. Also on the joint Brückner Group stand, visitors got the chance to meet Kiefel, showing the latest developments for the packaging, automotive, medical and appliance industry.

New large-surface light-emitting plastic film from VTT
VTT Technical Research Centre of Finland has developed an opportunity to create patterned and flexible light-emitting surfaces using OLED technology (Organic Light-Emitting Diode) implemented by a printing machine. These can be used on advertising displays, info signs and lighting fixtures, for example, and the method also enables transparent smart surfaces to be attached to window panels or packaging.
OLED technology is commonly used in mobile phone displays and television sets, though until now has only been found in glass surfaces, implemented using traditional microelectronics manufacturing methods. Using VTT's method, OLED elements can now be printed not only onto

glass or steel surfaces but also onto flexible plastic films, enabling significantly larger light surfaces and expanding the usage possibilities of the technology.
This type of light-emitting plastic film and
processing in ambient atmosphere has not been created before on this scale. Traditional printing methods such as gravure and screen printing, enabling very large production volumes, are used for manufacturing OLED light surfaces. Production is possible in facilities such as traditional printing houses. It is also possible to use OLED light as a transmitter in wireless data transfer. “The plastic film is optimally suited to advertising campaigns, in which large light- emitting surfaces can be used to draw significantly more attention than can be
gained through mere printed graphics or e- ink-type black-and-white displays that do not emit light,” says head of research area Raimo Korhonen from VTT.
