Pharma & healthcare
In the pharmaceutical and healthcare industry, product safety, hygiene and sterility are critical requirements.
At the same time, sustainability, recyclability and plastic-free packaging solutions are becoming increasingly important in regulated packaging environments.
With NP® SiOPack® , a water-based, inorganic SiO₂barrier coating technology for pharmaceutical and medical packaging, enabling paper-based packaging materials to achieve a reliable functional barrier against moisture, oils and microorganisms – without the use of polymer-based coating.
The technology enables food-contact compliant and hygienic paper-based packaging solutions that are industrially scalable and process-reliable. It represents an innovative and sustainable alternative to conventional plastic-based barrier systems, while meeting the strict regulatory and functional requirements of the pharmaceutical and healthcare sectors.
NP® SiOPack® uses a water-based sol-gel process to apply an ultra-thin SiO₂ layer (5-100 nm) to the paper surfaces.
After drying, a chemically stable, glass-like surface is formed, combining hydrophobic and oleophobic properties.
The coating remains mechanically flexible and does not affect the tactile properties or visual appearance of the base material. At the same time, it provides a high-performance functional barrier coating for paper-based pharmaceutical and medical packaging, fulfilling the demanding protection and hygiene standards required in regulated packaging applications.
The SiO₂barrier coating can be integrated into various paper-based pharmaceutical and medical packaging applications, enabling safe, hygienic, recyclable and sustainable packaging solutions that meet industry regulations.
The NP® SiOPack® approach provides the cosmetics and chemicals industries with a sustainable, food-contact compliant and process-compatible solution that combines functionality with regulatory compliance — ideal for the development of innovative, environmentally responsible packaging solutions.
