There is little doubt where we are heading: multilayer packaging will have to become easier to recycle – but what does that mean for the technology? And what solutions will the market need and accept? Manufacturers of branded goods are not the only ones who will have to rethink their specifications.

Europe Needs to Catch up

With innovations in metrology, processing and automation, the film industry is again pursuing the goal of process optimization and digitalization this year. But efficiency and sustainability are also the focus of the machine manufacturers, who will be serving up pioneering innovations at K 2019.

The Circular Economy – Sustainable yet Efficient?

A Perfect Concept All Round

A machine manufacturer is expanding its wide program of cast and blown film lines with a system for water-quenched blown film extrusion. This provides a unique system portfolio for the production of flexible packaging. The article presents these extrusion processes, their specific characteristics and the resulting application areas.

Beumer Group packs a wide variety of goods using its stretch hood lines and films that are often custom-made. Safely and economically.

Stretch hood lines are initially more expensive than stretch wrapping lines. However, they offer an advantage for many tasks

Special Requirements of Jam and Roof Tiles

The increasing volume of plastic waste and the growing pollution of the oceans by such waste have brought the sustainable handling of plastic products into the focus of society and politics. Both recycling and bioplastics can be a part of a strategy for greater sustainability, but they are not free of side effects. In order to avoid irrational decisions, it is important to assess their effects comprehensively.

If a film is used in the packaging sector, it should be made of at least a recycled material – leading to the common opinion that assumes that materials in circulation are automatically more sustainable. However, a detailed life cycle analysis, which considers all relevant energy and material flows on the basis of a generally valid calculation method, shows that it is not that simple

Why Recycled Films Are Not Necessarily Sustainable

Desire for hygiene and food safety increase worldwide demand for flexible packaging films.

What defects can the systems detect? Can the measurement data be used for process control? What is the technical standard and how are the inspection systems used?

Film inspection system in a blown film line: the image processing systems detect surface defects such as gels, black specks, fish eyes, coating cracks, streaks, flow lines or insects.

On the Spot at Windmöller & Hölscher

Brückner Maschinenbau focuses its trade show presence on higher plant efficiency and sustainable film production.

BOPP and BOPET are among the most popular packaging films. They are now produced on lines at speeds of over 600 m/min.

World premieres, technological advancements and joint projects: there was plenty of evidence at K of the impressive progress made in sustainable solutions in extrusion in many different directions over the past number of years.

During the daily machine show, Windmöller & Hölscher demonstrated a fast product changeover per autopilot. When K finished, the line was delivered to IsoFlex Packaging, in Nashville, TN/USA.

In the field of film extrusion and processing the number one topic at this year's K was the circular economy and sustainability.

A Common Goal: The Circular Economy

In October 2008 the plant and equipment manufacturer Kuhne GmbH hosted the first “Kuhne Autumn Week“. The very latest developments in blown and flat film manufacture were presented to an international audience at their headquarters in Sankt Augustin, Germany. A range of informative presentations by guest speakers rounded off the in-house exhibition. Alongside issues relating to specific materials, aspects of measurement and control technology were discussed. 

Extrusion: Spotlight on Film 

Until now, materials and processes have been colored holograms in large print runs. This could all change thanks to a new holographic photopolymer. A specially developed polycarbonate film with application-oriented material properties has proved a suitable carrier material for this photopolymer in the high-security holograms sector.

The current range of packaging films extends from shrink wrapping film via synthetic paper through films made from biopolymers. From these materials packagers can themselves design a packaging unit to suit their needs. This survey points out the possibilities, including advantages and disadvantages, that the various materials and their associated processing methods afford for the production of an economical and attractive package. 

Film Design: Packaging with the Right Film 

It is not possible to detect flaws on surfaces with complex texture patterns, e.g. artificial leather, using commercially available film inspection systems. By incorporating texture analysis algorithms into the film inspection system, comprehensive quality control is now also possible for these products.

Brückner Maschinenbau Places Major Order with Coperion

Brückner Maschinenbau has placed an order with Coperion for more than 50 ZSK Mc18 twin screw extruders.

Brückner Maschinenbau, a leading manufacturer of film stretching lines, has placed an order with Coperion for more than 50 ZSK Mc18 twin screw extruders. These will be integrated into plants for the production of flexible BOPET packaging films, which Brückner will install in China. The ZSK extruders have screw diameters ranging from 70 to 177 mm.

Brückner Maschinenbau’s substantial repeat order is based on many years of close cooperation with Coperion. With this order, Brückner is once again putting their trust in proven Coperion technology, which the company has already integrated into numerous film stretching lines. The ZSK extruders are used to melt the compounds that are fed into the lines. Thanks to their high torque, Coperion’s ZSK Mc18 extruders achieve very high throughput rates while maintaining low product temperatures and thus ensuring first-class product quality.

“We are very pleased that Brückner Maschinenbau is once again relying on our technology and know-how,” says Jochen Schofer, Business Segment Manager Recycling & Direct Extrusion at Coperion. “We very much appreciate this familiar, long-standing cooperation with the pioneer for plastic film lines. Our companies pursue very similar aspirations. We both develop high-quality technologies for plastics production with very high throughput rates. The efficient use of resources and high recyclability of the end products are important to us.”
