MDO (machine direction orientation) can be used for the production of polymer films that have unique properties. By using an optimized machine and control technology, existing MDO applications can be produced much more efficiently and new areas opened up.

Stretching the Limits  

A new method for foam extrusion combines the advantages of physical and chemical blowing agents. Solid carbon dioxide (dry ice) pressed into pellets is used as blowing agent that is added via the extruder hopper. The foaming method, which is simple to retrofit, provides a good entry-level solution to foam extrusion.

Since the recent market trend is gradually growing more in favour of synthetic components than bituminous ones, Amut S.p.A., Novara, Italy, now offers extrusion lines producing waterproofing membranes capable to process different thermoplastic materials, such as F/PVC, TPO, TPE in a single step. The use of these materials improves the technical performances and the physical features of the membrane, complying with international standards and requirements in the civil works sector.

Like plastics manufacturing and processing, the recycling of plastic products requires specialization to be efficient. Accordingly, a Dutch company has dedicated itself entirely to the recycling of agricultural and packaging films ¿ and invested in a machine technology, which was found along tortuous ways.

The Institute for Plastics Processing in Aachen is drumming up support for an innovative event that will demonstrate diversity and present the unexpected. Even the event's initiator, Prof. Hopmann, is keyed up and can't wait to see what will be presented there ¿ as he divulged to us in an interview.

Call for papers for a symposium for lateral thinkers  

As already known since the previous K, “EVO Ultra Flat” from Reifenhäuser Blown Film GmbH, Worms, Germany, improves the flatness properties of blown film. A new laser-measurement system now enables the improvement to be quantified precisely: laminating and barrier films are up to 40  % flatter while sagging is reduced by up to 90  %. The measuring unit records the topography of the fine film web and then sets the correct production parameters. Reifenhäuser will be demonstrating at its booth how this ultra-flat measurement with integrated closed loop control functions.

Not only the interest of tuning experts has recently focused on design in the engine compartment. Previously, the most conspicuous element – the motor cover – was expected primarily to meet acoustic demands, but to an increasing extent this component has now become an object for design. Decorative film layers can provide increased freedom of design whilst simplifying its implementation.

Electrostatic charging may cause problems in the production of plastics and plastic semi-finished products. A new generation of ionizers meters the charge in an object, and then discharges it in a precise and reliable way.

The demands placed on packaging films are so multifaceted that they can only be met by combining different raw material components. This in turn requires blown film dies that are able to process a wide range of materials and thus provide greater flexibility for the film manufacturer.

Jointly organized by the Institut für Produkt Engineering (IPE) and Hanser Publishers on March 12–13 in Duisburg, Germany, and with well over 100 participants, the conference was a great success. The participants enjoyed highly topical subjects, top-class speakers, and lively discussions hosted by Professor Johannes Wortberg.

It was not only the 5-layer coextrusion blown film system itself that attracted around 100 visitors to the plant of Kuhne GmbH, in St. Augustin, Germany, at the beginning of April, but also the manner in which it was presented. Over a period of two weeks, the machinery manufacturer gave visitors the opportunity to participate in the first test and production runs of the 20 m high system, which stood completely assembled in the technical center.

Brückner delivers sequential film stretching lines 

Xiamen Changsu orders production line for BOPA film 

The Chinese global film supplier invests in two 7-m sequential film stretching lines for the production of BOPA films. 

The Chinese BOPA film producer Xiamen Changsu just now ordered two new sequential film stretching lines from Brückner Maschinenbau which are, according to their own information, the fastest, widest and most powerful of their kind so far: a working width of 7+m, a production speed of 340 m/min and an output of more than 2.5 tons per hour have not been achieved yet. 

Mr. Wang Zhefu, Chairman of Xiamen Changsu says: „When we decided to make this investment, we had a clear goal in mind: lowest production costs with highest film quality at the same time. The new lines surpass our largest machines to date by 35% in speed and 50% in output. And based on our long-lasting experience with the Brückner technology we can safely assume outstanding film qualities with the finishing characteristics our customers expect.” 

Reinhard Priller, Sales Director Brückner Maschinenbau, adds: „The new lines also mark the latest development stage in the field of sequential PA film stretching: From 4.2 to 5.1 to 6.6 meter we now reached a proud 7+ meters. And Xiamen Changsu made all these steps along with us.“ 

The lines are to start production in the last quarter 2021, right in time to produce film for the year´s end business.
