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.
Key benefits at a glance
High transparency for clear product visibility
