More than 20 years of Sol-Gel innovation - built on patents, intellectual property rights and proprietary know-how.
As early as 2007, nanopool developed the first chemically inert, water-based SiO₂ sol-gel coating for paper, board and moulded fibre products – long before sustainability became an industrial benchmark.
SiOPack® is a transparent coating technology for paper, developed and manufactured by nanopool in Germany.
The glass-like protective layer, just 5–100 nm thick, completely replaces conventional polymer barriers:
100% plastic-free, PFAS-free, SUPD-compliant, compostable and recyclable within the paper recycling stream.
Developed and manufactured in Germany – validated through international testing and recognised with multiple awards.
From an idea to international recognition:
More than 20 years of Sol-Gel innovation - built on patents, intellectual property rights and proprietary know-how.
As early as 2007, Nanopool developed the first chemically inert, water-based SiO₂ sol-gel barrier coating for paper,
carton and fibre-based packaging materials – long before sustainability became an industrial benchmark.
The glass-like protective layer, just 5–100 nm thick, completely replaces conventional polymer barriers:
100% plastic-free, PFAS-free, SUPD-compliant, compostable and recyclable within the paper recycling stream.
NP® SiOPack® is based on an advanced water-based sol-gel coating technology that deposits an ultra-thin SiO₂ layer (5–100 nm) onto fibre-based substrate This glass-like yet flexible surface forms a durable and transparent functional barrier layer, preserving the natural appearance, tactile properties and printability of the base material.
NP® SiOPack® is based on a water-based sol-gel process in which a SiO₂ layer just 5-100 nm thick is applied to fibre-based materials.
This glass-like, elastic surface forms a durable, transparent barrier that leaves the feel and look of the base material unchanged.
The SiO₂ barrier coating is designed for a wide range of industrial packaging applications and can be seamlessly integrated into existing production lines via inline or offline processing. The technology is already successfully used across multiple sectors:
The innovative performance of NP® SiOPack® has received several international awards - including the Green Apple Award, Green Product Award, the Golden Green World Award and the CFI Award „Best Green Alternative Innovation Europe“.
These recognitions confirm the strong technological performance, regulatory compliance and environmental value of this next-generation sustainable packaging barrier solution.
