Comexi, a global leader in flexible packaging machinery, arrives at Interpack (Stand 8A F54) with a disruptive message for Brand Owners: sustainability is no longer a cost, but a driver for industrial efficiency. By integrating advanced printing, laminating, and slitting and laser ecosystems, Comexi enables the creation of innovative packaging that reduces CO2 footprint and VOC emissions while improving the bottom line through optimized design and energy-efficient production.
Strategic Seminar: The 4th Sustainable Packaging Showroom
A cornerstone of Comexi’s presence is the 4th edition of the Sustainable Packaging Showroom, taking place on May 11. The event features a high-level technical block in Hall 10, room 10.1.
This seminar will move beyond general concepts to focus on tangible industrial advantages: solvent-free processes, VOC (Volatile Organic Compound) reduction, and energy efficiency. Experts from Comexi and industry partners will discuss how these factors, integrated both into machinery design and the packaging structure itself, drastically reduce the environmental impact of the final product while enhancing cost-competitiveness
Four examples of efficient sustainability
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-based inks for a high-quality, solvent-free printing featuring 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 reducing 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 recyclable packaging (ALL PE) in a sustainable way (Reduction of Solvent use with EB inks) and at a lower total cost (Changing one lamination process by an OPV applied directly on the CI).
* The superior properties of EB inks provide an 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
A Holistic Approach to Circularity
These applications are only a glimpse into the extensive range of sustainable solutions Comexi will present, including functional coatings, solvent-free lamination, and variable data coding for total traceability. A major highlight for brand owners seeking high-recycled content is Comexi Sliing’s latest solution: by integrating ESI’s EB (Electron Beam) technology directly into the slier, the process enables crosslinking that improves the surface resistance of the PE materials.
Comexi’s technology is engineered to minimize waste and energy consumption. For brand owners, this means achieving sustainability targets without compromising the performance or the visual identity that defines their products on the global stage.
