In the case of DÜPOLEX® bags and sacks, an electrically conductive, black special coating (≤ 105 Ω) is applied by grid printing to a highly pure pharma-grade carrier material. Due to the absence of migrating antistatic agents, the film is film can be stored for longer and can also be reliably used in the very dry process air (humidity approx. 30%) in filling plants.
filling plants (humidity approx. 30%). In addition, it meets the stringent cleanliness and hygiene requirements of the pharmaceutical and hygiene requirements of the pharmaceutical industry, because the print is applied exclusively to the outside: clean and abrasion-resistant. This means that APIs and intermediates can be packaged safely and securely because they are
only come into contact with the high-purity, already approved pharmaceutical film. In addition, the
filling process can be better monitored thanks to the transparency. Thanks to the consistent use of a monofilm and recyclable printing ink, DÜPOLEX® meets all requirements for easy recyclability. After an extensive test phase, companies such as BAYER are relying on the innovative product.

It was the exciting application developments around the plastic polyethylene (PE) in the nearby BASF that laid the foundation for RHEIN-PLAST, with today's headquarters in Bad Dürkheim/Pfalz, as early as 1959. Since then, 3 generations of the Eisemann family have been engaged in offering tailor-made bags and sacks made of PE monofoil to demanding customers from all over the world and from a wide variety of industrial sectors.
In the meantime, the main customers are large groups from the pharmaceutical, biotechnology and medical industries. However, RHEIN-PLAST also develops packaging solutions for special applications and products in the food and chemical industries, i.e. wherever hygienic, pure and top quality packaging is required. These include pharmaceutical-grade, electrically conductive films for customers such as Bayer, as well as innovative special solutions for many global players in the pharmaceutical industry. Well-known automotive suppliers also have the packaging materials specially adapted to them manufactured by the medium-sized company with 85 employees. RHEIN-PLAST has its own extrusion department with 17 lines, a second hall for packaging and an in-house print shop for film printing.
Since February 2022, RHEIN-PLAST has been a member of the RINGMETALL SE group of companies, where, together with sister companies Nittel Halle GmbH and Tesseraux GmbH, it forms a three-man team of packaging experts, the INDUSTRIAL PACKAGING LINER division (booth 9-237).
