Film manufacturers who are producing 3-layer film on older lines have noticed that they can no longer compete with new, high-performance BOPP lines. A qualified line modification to 5- or 7-layer technology provides for the possibility of producing new products and entering new highmargin markets with a reasonably modest investment.

Film Stretching Technology: Fitness Program for New Markets 

Multi-layer cast films can be created using a multi-manifold die or by means of an injector block and an end-fed die. The numerical simulation helps to better understand the coextrusion process for polyester films and the emergence of clear edges. In addition, it can be determined how different viscosities influence the film structure.

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.

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.

On March 19 and 20, 2014, the Institute of Plastics Processing (IKV) is presenting another International Colloquium of Plastics Technology. With the slogan “Nachwuchs, Netzwerk, Innovationen” (New Generation, Network, Innovations), the research crucible is presenting its entire portfolio. Visitors can look forward to a revised event concept with top-class talks and innovative processing techniques.

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.

Air-quenched blown film was solely a domain of polyethylene until a few years ago. With the polypropylene grades that have since been introduced into this area of processing technology, the application and property spectrum of films produced by this method has considerably widened. New product developments in the area of random and heterophase copolymers are taking account of this trend and permitting economic solutions in the packaging sector.

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.
