Mono is alive and bio is coming

About 120 experts from 20 countries were in attendance at Polyrema’s Open House event that took place in Troisdorf-Bergheim, Germany at the end of last year. The visitors used the opportunity to see the new mono-layer blown film line in operation and take a close look at it.

Manfred Kurscheid, managing director of POLYREMA, led through the programme and answered central questions around the Open House and the changing market for film products.

When the doors of the Technology Centre opened on December 2 and 3, POLYREMA presented a line that had just been ordered by a customer featuring exactly the details that the company originally wanted to present in the run-up to the plastics trade fair, K 2016 in Düsseldorf. The single-layer (‘mono’) blown film line was extensively tested under production conditions on two days: On the first day, HDPE film was run while on the second day, a biodegradable film from BASF resin was produced.

The ubiquitous HDPE films used as ultra-thin T-shirt carrier bags for fresh produce are one of the reasons for the growing trend towards the new ecological films that are demanded above all in France today. Kurscheid said: “Shopping bags made from this kind of film can be reused as bio-waste bags or they can be composted. The new line can produce both types of films: classical and biodegradable ones.”

However, the focus of the event was not only on ultra-light bag film. POLYREMA demonstrated that the capabilities of mono-layer lines are far beyond this application: With an additionally installed Ultra Flat Plus unit it is possible to produce a high-quality film of slightly increased strength which can be laminated and coated. Marcel Perrevort, sales director at POLYREMA, added: “This film can also be laminated with paper to produce, for example, the typical wrap film for butter packaging.”

A further highlight presented by POLYREMA for the production of biofilm is a special screw cooling system installed in the Reifenhäuser extruder.

It was just these quality features that made the customer, whose line was in the focus at the Open House event, opt for the POLYREMA line. In the future, the company will produce on it mainly draw tapes for garbage bags. The customer puts high value on a superior-quality film with low stretching behaviour to prevent that heavy garbage bags are becoming longer and longer on the path to the dustbin.

“We also want to convince other customers of our approach and provide proof of the fact that there is a broad and still growing range of applications for mono films.”

Visitors from many branches of the plastics processing industry came to the first Open House of POLYREMA, including those from SMEs and big concerns from all over the world.
