Sustainable flexible packaging is becoming a strategic priority for brand owners facing stricter environmental regulations and increasing pressure to reduce the environmental impact of their products. Companies across the packaging industry are actively seeking sustainable packaging solutions that allow them to maintain product performance while improving recyclability and reducing the CO2 footprint of packaging production.
At Interpack 2026 in Düsseldorf (Stand 8A F54), Comexi will present a portfolio of ready-to-market applications designed to help brand owners address these challenges. By integrating advanced printing, laminating, slitting and laser technologies, the company enables packaging structures that reduce CO2 footprints and VOC emissions while improving production efficiency and lowering operational costs.
This approach demonstrates that sustainable flexible packaging is no longer only about environmental responsibility. When properly implemented, it can also become a driver of industrial efficiency and competitiveness.
Sustainable packaging solutions for brand owners
A key highlight of Comexi’s presence at Interpack will be the 4th edition of the Sustainable Packaging Showroom, taking place on May 11, from 10:00 AM to 5:00 PM, with a dedicated technical session from 2:00 PM to 5:00 PM in Hall 10, room 10.1.
The seminar will focus on practical industrial advantages rather than general sustainability concepts. Experts from Comexi and industry partners will explain how new technologies can help companies move toward more sustainable flexible packaging production.
The technical session will address topics such as:
• Solvent-free production processes
• Reduction of VOC emissions
• Energy-efficient packaging production
• Packaging structures designed to improve recyclability
By combining optimized packaging design with advanced machinery, converters can reduce material consumption and develop sustainable packaging solutions aligned with evolving European regulations.
Recyclable packaging innovations presented by Comexi
While Comexi will display a vast array of solutions, these four applications highlight how sustainable design can lead to material and economic savings:
- Cost-Efficient Recyclable Pet Food Packaging: This innovative pouch is made from a recyclable BOPP monostructure.
- Printed using water base inks for a High-quality Solvent Free printing featuring a high-definition graphics.
- It eliminates the need for expensive plastic zippers by using a horseshoe-shaped opening created with COMEXI LASER technology.
- The closure is maintained through a resealable BOPP label, which enhances ergonomics.
- This design increases production speed on packaging lines and provides significant material savings for the packager.
2. Monolayer Efficiency via Hybrid EB Flexo: This recyclable PE monomaterial and monolayer solution achieves a lower CO2 footprint thanks to the use of Flexo ElectronBeam inks, while at the same time reduces the production costs as it eliminates the lamination process entirely.
- This project, made in collaboration with Coveris showcases how changing the structures we can make a reciclable packaging (ALL PE) in a sustainable way (Reduction of Solvent use with EB inks) and at lower total cost (Changing one lamination process by an OPV applied direct on the CI).
- The superior properties of EB inks provide and excellent visual featuring strong colors and high-definition highlights, while the EB varnish provides the surface protection for the inks. The required barrier properties are provided by the Coextruded PE structure.
- It features an easy-open system, showcasing Comexi’s versatile laser that works efficiently across both extrusion and monomaterial lamination without needing separate equipment.
3. Paper-Based Packaging (FREEcure): For brands transitioning to paper, Comexi presents a surface printing solution powered by EB (Electron Beam) & FREEcure technology, printed in Offset CI Technology.
- The inks and varnishes are photoinitiator-free, for use in food packaging
- It offers high opacity white and an excellent color gamut at high production speeds without trapping issues.
- The offset technology is compatible with both paper and films.
- Project made in collaboration with Lecta, IST and Sunchemical
4. Circular Detergent Pouches with 40% PCR: This MDOPE + PE monomaterial pouch is designed for recyclability.
- It demonstrates that incorporating over 40% recycled resin from household waste does not require a sacrifice in shelf appeal.
- Printed with Offset CI technology, it offers a sustainable solution ready for European standards that remains competitive in cost while offering the best high-definition aesthetics.
- The pouches are presented in two versions: one is reverse printed and laminated, and the other is just a printed surface on the same structure.
- Project made in collaboration with Dow, Mespack and Reifenhauser
Advancing sustainable flexible packaging and CO2 footprint reduction
These examples represent only part of the sustainable packaging solutions that Comexi will showcase at Interpack.
The company continues to develop technologies that support the transition toward more sustainable flexible packaging production, helping converters and brand owners achieve objectives such as:
• Developing recyclable packaging structures
• Implementing monomaterial packaging strategies
• Reducing the CO2 footprint of packaging production
• Improving energy efficiency in manufacturing processes
By combining advanced machinery with optimized packaging design, Comexi enables companies to reduce environmental impact while maintaining industrial efficiency and product performance.
