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.

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.

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.

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.

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

Even more than with foodstuffs, what matters in most cases with drug packaging is the contents protected by the wrapping. These are not good conditions to pursue a cycle concept for packaging. But times are changing – perhaps.

Steps to More Sustainable Packaging in the Medical and Cosmetics Industries

No Chance for the Cycle Concept?

Contrary to the current perception, plastics, as a component of packaging materials, often represent the most environmentally sound option. The plastics industry is currently undergoing a transformation, shifting the focus onto the realization of closed material loops as well as reducing the resource input with highly efficient materials.

Resisting the Pressure

The goal of the European Union (EU) to recycle all plastic packaging in Europe in an economically viable manner by 2030 is exerting enormous pressure on the packaging industry. It is very common that packaging films are made of different materials, and this causes challenges since they are often not easy to recycle.

Can One Material Be Enough?

The challenges associated with recycling food packaging are particularly great in the flexible-packaging sector. Multilayer composites are often a hindrance to mechanical recycling, yet are irreplaceable in many applications. Replacements will not be found until recyclable and ecologically sustainable packaging solutions are devised.

Compared with conventional thermoforming molds made from epoxy resins or aluminum, a new type of casting resin system not only enables heat-resistant and high-quality thermoforming molds to be produced in a much shorter time, but the user can make the molds himself. The system can also serve as an alternative to injection molding to achieve a favorable price-performance ratio.

Extrusion blow molding enables cost-effective production of hollow plastic articles with complex geometries and differing volumes. One disadvantage, however, is that blow-molded components often fail at the weld line. Variothermal temperature control can be utilized to significantly improve the quality of the weld line.
