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.

In 2013, Reifenhäuser introduced the high-performance extrusion lines for PET thermoforming sheets with the patented mechatronic polishing stacks of the MIREX-MT-V design series. Now Reifenhäuser introduces the next generation of this line type.

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.

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.

Cracks often appear on screws and unsettle customers. The manufacturer EJS is often confronted with this effect and has got to the bottom of it.

The range of offerings from the manufacturers of machines for film and sheet was almost impossible to take in: there were 64 exhibitors in the area of blown film and 105 in the field of flat film and sheet extrusion. As usual the achievable output rate of the systems above all was a key topic for many plant constructors. Keywords such as high speed machines, low temperature screws as well as improved cooling and winding concepts were crucial points in discussions. Furthermore, the processing of PET was also once again a hotly debated topic.

Previously it was not possible to apply a solar protection film on acrylic or polycarbonate (PC) substrates without blisters being formed. Plastic S15 which was developed by 3M Deutschland GmbH, Neuss, Germany, is the first protective polyester film that can be blister-free bonded to PC or acrylic substrates. This has been made possible by a special aging resistant acrylic adhesive system that hinders blister formation in spite of outgasings from the polymer.

Décor films based on polyamide are replacing varnishing in the area of engine covers, giving them precious metallic looks. For several years already, films have been successfully used as protective and decorative elements in sports articles. They impress consumers by their constantly new and sumptuous designs.

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.

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.
