Statutory recyclate quotas and the specifications of brand-name producers are weighing heavily on the packaging branch these days and turning recyclate availability into a hot issue. Some polymers are simply not available in sufficient amounts. Experts at the 31st Dresden Packaging Conference provided insights into the current situations and explained why the situation could worsen in the future.

Recyclates of many polymer types are hard to get right now.

Sustainability is the megatrend of our times. And the hype surrounding the circular economy is not mere utopia, it is a realistic goal.

Next Goal: Circular Economy

In the interest of sustainability, film extrusion plants have to process recycled materials and also produce recyclable products. Monomaterial products and a plant layout optimized for the products are the current trends. A multilayer structure as such does not pose a problem for recycling as long as all layers are made from the same class of plastic. Digitization continues to be an important driving force as digital tools contribute to solving the problems that need to be overcome.

When Less Is More

Apart from injection molding and in-mold labeling (IML) additional automation steps are necessary to make the entire process for producing container packaging as efficient as possible. For this purpose, Beck Automation offers customer-specific solutions for the downstream handling of such packaging.

Downstream automation, like the packaging of drinking cups in cartons, increases efficiency and reduces the risk of contamination by persons

In plastics processing, efficient production methods are required, especially for articles with high volumes and exacting quality requirements, and these must be constantly optimized. The container specialist Walther Faltsysteme has been successfully working together with the Austrian moldmaker Haidlmair for many years.

Ultra high performance polymers such as polyaryletherketones (PAEK) are typically not thermoformable for thick gauge applications because of their semi-crystalline nature.

Styrenics can be polymerized using different technologies and it can be modified with a range of copolymers. The resulting plastics offer a wide range of properties allowing to customize them for different applications. Because of this range of properties they are suitable for many industries. Strong demand is for example driven by the automotive industry, healthcare and the packaging industry.

Styrene copolymers are frequently used in the exterior of vehicles. The Chinese manufacturer Lixiang, for example, uses an ASA for the radiator grill of its electric vehicles

Diverse Shapes and Applications

Continuous Compression Molding (CCM) technology can be applied to multilayer solutions and is referred to as Continuous Compression Molding Multilayer (CCMM). In addition to the usual benefits of CCM it offers further advantages over competing technologies. In packaging applications, compression technology makes it possible to use minimal quantities of barrier material, thus combining excellent performance with low raw material costs.

Paying Attention to Layers in-between

In order to avoid bubble ruptures during the production of blown film, the velocity of the cooling air is often reduced. The use of air guiding systems (AGS) can prevent such bubble instability. A novel AGS was developed at IKV in Aachen, Germany, using iris diaphragms in order to increase the cooling efficiency of blown film extrusion and thus improve the productivity of an existing plant

For almost two decades, an expert committee, meeting once a year, has supported Kunststoffe magazine in determining the state of play in the plastics industry and identifying current technical developments. This time, the traditional spring meeting gave it an opportunity to debate the consequences of the Corona virus.

Taking new paths: during the Corona crisis, certain technical obstacles were also overcome by the Kunststoffe publisher advisory committee, who held a round table discussion by video conference for the first time. Present by video link were, among others, (top, from left) Dr. Guiscard Glück, Prof. Christian Hopmann (bottom, from left) Martin Würtele and Dr. Achim Eggert
