Glassine
Glassine by SiOPack® is a paper-based solution that, for the first time, enables high transparency and can replace conventional plastic windows in packaging. Developed using SiOPack®-technology, the material combines design, sustainability and industrial feasibility.
A new option for transparent packaging
Transparent viewing windows have traditionally relied on plastic films. These complicate recycling and increase material complexity.
Glassine by SiOPack® offers a paper-based alternative – fully recyclable and compatible with existing processes.
Plastic-free folding carton with Glassine viewing window - FACHPACK 2025
At FACHPACK 2025, SiOPack presented® Together with Optima, an innovative folding carton with transparent viewing window based on Glassine by SiOPack®. The solution shows how classic plastic windows can be replaced by a paper-based alternative - with a high level of transparency and recyclability in the paper stream.
The packaging presented combines product visibility with sustainable design and is particularly suitable for applications in the food, consumer goods and high-quality packaging sectors.
