Flexible, sustainable pharmaceutical packaging

In the field of secondary packaging, IWK will present for the first time at interpack the latest‑generation horizontal cartoning platform. At the show, the CH4 cartoner will package injection pens into sturdy cardboard trays that are automatically inserted into folding cartons. Both the folding cartons and trays are produced by partner Kartonveredelung Knapp.

The CH platform combines precise carton positioning with high flexibility and outstanding energy efficiency. An innovative servo drive recuperation system significantly reduces energy consumption by up to 21%. The linear process layout allows for fast, reproducible, tool‑free format changes. Thanks to its modular design, the platform is highly future‑proof and suitable for a wide range of applications in pharmaceuticals, cosmetics, and non‑food.

Process‑reliable ultrasonic sealing technology

IWK is also setting new standards in tube filling technology. Tubes are sealed using ultrasonic technology, which offers several advantages over the conventional hot‑air process. High‑frequency mechanical vibrations generate the required heat directly within the material, allowing the sealing surfaces to be welded locally and with exceptional control. This makes the process highly energy‑efficient. Even with creamy, oily, or pasty products, clean, secure, and reproducible seals can be achieved. In addition, the ultrasonic unit is immediately ready for operation, as it requires no heating or cooling of sealing jaws.

For premium segments such as pharmaceuticals and cosmetics, flawless seam quality is critical. This technology therefore expands the possibilities for high‑quality tube sealing. Since no external heat is applied, both the material and decoration are protected, resulting in a visually clean and narrow weld seam – an aesthetic advantage for sophisticated brand presentations. At this station, IWK will also demonstrate a microdosing solution.

As the inventor of the tube filling machine, IWK has stood for maximum reliability, hygienic safety in accordance with GMP standards, and impressive performance ranges of 70 to 760 tubes per minute since 1893. Precise chain conveyors, smooth stainless‑steel surfaces, and a clear separation between drive and filling areas enable fast, clean, and safe filling processes – particularly important for sensitive pharmaceutical products.

Sustainable material diversity on the fastest blister machine

A special highlight at the IWK booth is the card‑to‑card material variability of the CABLIblue 870. The system produces robust, full‑cardboard blisters entirely without single‑use plastics, thereby addressing key requirements of the new EU Packaging and Packaging Waste Regulation (PPWR).

The blister system clearly demonstrates its future readiness: at interpack, the machine processes four different fiber‑based materials – virgin material, recycled fiber, grass fiber, and Silphium – simultaneously within an integrated forming and sealing process, a world first. IWK engineers will showcase how high‑quality full‑cardboard blisters can be manufactured efficiently, resource‑savingly, and with stable processes even under new regulatory conditions.

The lidding cards and matching blister hoods are supplied and premium‑produced by packaging specialist Karl Knauer KG. Live on the booth, a bamboo toothbrush and a toothpaste tube will be packaged – two products that exemplify the trend toward plastic‑free packaging solutions.

With its modular design, ergonomic stations, and exceptional material diversity, the CABLIblue 870 not only meets current market demands but also future regulatory requirements for recyclability, material reduction, and sustainable packaging design. It is ideally suited for cosmetics, DIY products, medical technology, and pharmaceutical applications – industries in which sustainable packaging transformation is progressing particularly rapidly.

With its card‑to‑card technology, IWK positions itself as a forward‑thinking design partner that does not merely react to market changes but actively develops new solutions. The CABLIblue 870 exemplifies how IWK develops innovative technologies that support companies in transitioning to paper‑ and fiber‑based packaging – making a decisive contribution to plastic reduction, compliance with future regulations, and the establishment of a true circular economy.

Comprehensive service portfolio

In addition to the numerous trade show highlights, IWK will present further key topics from its overall portfolio as well as service offerings in the areas of maintenance and aftersales. IWK Service focuses on global availability, technical expertise, and comprehensive support throughout the entire machine lifecycle. This includes preventive maintenance, rapid spare parts supply, process optimization, and a broad training program at the Technical Training Center. The goal is maximum machine availability, safe production processes, and fast response times – whether by phone, digitally, or directly on site.
