Packaging Trends
High speed of innovation
Packaging-related mechanical engineering in Europe has a decades-long tradition to call upon. The histories of the German companies Jagenberg, Hesser and IWK, for example, reach back into the 19th century. After the war, new companies are founded all over the world. Within a few years, Germany is one of the leading exporting nations in packaging machinery. As in other areas of the economy as well, there is a concentration process in the industry because small companies find it more difficult to keep up with the pace of innovation.
Fast but isolated
The packaging industry has increased the production quantities and upped the pace and now faces the problem of bottlenecks in primary and secondary packaging. The designers of the packaging machines therefore attempt to increase the output quantities of their models. The joining-together of individual machines into lines is developed by the industry, but can only be partially realized. The integration of weighing and dosing machines into the packaging process, on the other hand, is accomplished successfully. The range of photoelectric counting devices is also improved. With the model PZG 3 from the company Firma R. Weber (Germany), magnets and couplers can be switched in less than 1/100 of a second: A speed which packaging machines are still a long way off achieving in practice.

A sensation for pharmaceuticals (1958)

At interpack in 1958, Höfliger & Karg (now Bosch Packaging Technology, D) presented the art of packaging machine construction from the 1950s with a filling and packaging machine for coated tablets. The synchronization of six individual machines into one line was a special achievement. The unit, which was named the “Bellergal line“ after the drug it packaged, could be viewed in operation at the exhibition stand. The output was up to 4,800 packs per hour.
In-line packaging (1958)

The finest engineering can be found in this new machine, which was launched in 1958 by three design engineers in Paris. It was the first continuous form, fill and seal machine. The three partners applied for a patent and formed the company Plastmecanique, which now operates under the name of Erca-Formseal (today Oystar Erca-Formseal, F).
Controlling and regulating (1958)

In 1958, Siemens (D) launched Simatic, a series of ready-wired, electronic systems for controlling and regulating small subtasks on production lines. These components contain a combination of logical functions with output amplifiers, enabling activation of contactors, solenoid valves or other control elements within one wired programmed controller.
