More sustainability, efficiency, and recyclability
Thanks to significantly improved heat resistance, BOPE films are now not only more recycling-friendly but also more versatile and faster to process. The varnish creates a broader processing window and reduces the risk of sticking to sealing jaws. In addition, higher sealing temperatures enable increased cycle times on machines, thereby enhancing the efficiency of the production process.

Another key advantage of this innovation is that hubergroup's Gecko 2-Component Varnish makes BOPE films suitable for pouch applications, which was previously a challenge due to the limited temperature resistance of BOPE films.

Technical features of Gecko 2-Component Varnish 70GL426590
The new varnish is ethanol-based and has been specially developed for applications requiring high chemical resistance. It is suitable for both flexographic and gravure printing processes and can be applied to a wide range of surfaces as well as for food and beverage packaging. Its outstanding properties include:
- Deep Freeze Resistance – Maintains integrity even at ultra-low temperatures
- Superior Ink Adhesion – Ensures vibrant and long-lasting print quality
- Exceptional Scratch Resistance – Protects packaging from wear and tear
- Outstanding Water Resistance – Shields against moisture exposure
- Brilliant High Gloss Finish – Enhances visual appeal and shelf presence
- Robust Rub Resistance – Withstands friction and handling stress
- High Solvent Resistance – Ideal for demanding packaging applications

Based on migration test results, the final printed varnish will comply with legal requirements for packaging of all types of food when printed on the non-food contact side.1

Sustainable Innovation and Practical Application
Additionally, the varnish is NC-free, making it future-proof concerning current and upcoming regulatory requirements for recycling printed packaging. This underscores hubergroup's commitment to sustainable and environmentally friendly packaging solutions.

The BOPE film printed with the new varnish also contained a proportion of recycled polyethylene. This film was successfully processed into a pouch as part of the PlastikBOND project by the Institute for Plastics Processing (IKV) in Industry and Trade at RWTH Aachen University.
