IA-05 Films and coatings for circular packaging

Expertise:

-Implementation of bio-based coatings for molded cellulose packaging using multi-layer technology (hyper-refined pulps and microfibrillated cellulose). Provides barrier properties, improve mechanical strength and reduce weight (m50g/m²), control surface finish and dust release.

-Chromatogeny treatment that provides hydrophobicity (CBE CELLUWIZ project - Food contact approved by BFRXXXVI in 08/2024)

-Application of new bio-based coatings to packaging papers using all coating and printing technologies (blade, spray, size press, printing, etc.).

-Printability expertise : assessment and recommendation for main industrial printing processes (offset, flexo, gravure, inkjet and screen) using several specific pilot presses and trials in industrial conditions

-Needs for new bio-based coatings for sealing the sheet structure and porosity, for high-performance barriers (water, vapor, gas, contaminants), and for bonding (hot-melt, cold-set, ultrasonic).

The Centre Technique du Papier (CTP) is an impact-driven organization and a key player in the ecological transition for the paper, board, fiber-based packaging and biomaterials industries. It supports companies and market players in adopting new materials, optimizing production and converting processes, and improving the environmental performance across the full life cycle of their products.

Equipped with pilot-scale platforms, CTP provides R&D, consulting, expert assessment, and laboratory and pilot services for the pulp, paper, board and related industries (including converters and printers).

Thanks to its expertise in fibers, recycling, plant-based chemistry and barrier solutions, it contributes to the development of sustainable alternatives to plastics and strengthens the competitiveness of the entire value chain.
