Polymer-Free Barrier Coatings for Paper Cups and Single-Use Packaging
NP® SiOPack® is nanopool GmbH’s polymer-free, silicon dioxide-based barrier technology for paper, paperboard and moulded fibre packaging. Our current partnering priority is paper drinking cups for hot and cold beverages, alongside other single-use food and beverage packaging applications.
Nanopool brings more than two decades of experience in functional surface technologies. Our expertise combines coating development, substrate-specific application and integration into industrial production. Industrial implementation of SiOPack® in carton packaging with Van Genechten Packaging was featured in Packaging Journal, and the technology received the Green Product Award 2022.
We are seeking cup manufacturers, packaging converters and food and beverage brands interested in implementing polymer-free barrier technology in their packaging. For drinking cups, our focus is on translating the barrier technology into finished products that meet the intended hot- or cold-beverage requirements.
Collaboration can include material selection, printing and application trials, finished-cup performance evaluation and production-line integration. Our objective is to establish commercially scalable packaging solutions together with industrial partners, with paper drinking cups as a lead application.
About Nanopool GmbH
Nanopool GmbH is a German nanotechnology research and development company founded in 2002 that specializes in functional surface coatings based on proprietary Liquid Glass (SiO2) technology. The company operates as a technology platform, focusing on the development and manufacturing of ultra-thin, transparent, and environmentally friendly protective layers. These coatings are engineered to provide surfaces with specific properties, such as water and dirt repellency, antimicrobial protection, and durability, while largely maintaining the original appearance, feel, and breathability of materials like glass, metal, plastic, textiles, and paper. Their products are developed through interdisciplinary research and are often patented or patent-pending, with a strong emphasis on sustainability and resource efficiency.
By providing tailored coating systems, Nanopool helps partners across diverse industries—including healthcare, construction, photovoltaics, and sustainable packaging—to enhance product performance, improve hygiene, and reduce maintenance requirements. Their SiOPack initiative, for instance, offers a recyclable, plastic-free barrier coating for paper-based packaging that protects against moisture and grease. The company’s solutions have been recognized with numerous scientific and environmental awards and are designed for integration into industrial production processes, helping customers achieve more durable, hygienic, and sustainable material applications.
