K2016 is approaching for Bandera

K2016 is approaching for BanderaAt K2016, visitors will have the chance to see Bandera’s latest high tech solutions for packaging and converting in action.
For example, a 5-layer coextrusion blown film line featuring top flexibility – suitable for producing both polyolefin and barrier film, equipped with an innovative device specifically designed by Bandera engineers to enhance film quality.

Moreover, simultaneously with K2016, an Open House will take place at Bandera’s The House of Extrusion® in Busto Arsizio, where other blown film lines and also flat die extrusion lines intended for rigid packaging sector will be live on show.

Nowadays, it is essential to combine specialisation and flexibility. At first glance, they are two contradicting concepts, but the market players increasingly demand them. For this reason, Bandera’s team act as pace setters to develop equipment with a view on both the aforementioned concepts. SmartFlex® and Techno FLEX® Plus series prove the above focus: capable of manufacturing different kinds of film, they maintain and ensure top level performance, and unrivalled quality. A further example is Bandera BarrierFlex® 7-layer extrusion line, a solution that offers top polyolefin film output capacity together with high barrier and lamination film production.
Last but not least, an ever increasingly crucial topic: industrial energy efficiency. Bandera is committed to minimising power consumption by developing new solutions focused on ensuring the most effective cost to performance ratio.

The packaging and converting sectors have a bright future. This global market is very important for Bandera. Requests for cutting edge technology are increasingly coming from every corner of the globe – the consolidated European trend is to look for very technical performing film combined with minimised costs, and to shift from mono- to 3-layer film, to get to the cutting edge 5-, 7- and 9-layer extrusion lines, according to customers’ final product. In order to promptly answer any customer’s requirement through cutting edge solutions, Bandera has always kept 100% of its research and development, design and manufacturing, extrusion line testing, and, last but not least, its precious know-how, in-house.
