Céline Guezennec defended her PhD thesis from the University of Grenoble entitled "Development of new packaging materials based on micro- and nano-fibrillated cellulose".

This thesis was prepared in the Laboratory of Pulp and Paper Science and Graphic Arts (LGP2) under the supervision of Professor Alain Dufresne from Grenoble INP-Pagora, and in the Centre Technique du Papier under the co-supervision of Florence Girard, Research Engineer.

The micro- and nanofibrillated cellulose (MFC/NFC) are nanomaterials from renewable resource with a high interest and partly for the packaging development. MFC combined both interesting properties (high tensile strength, good barrier to oxygen and grease, good transparency) and the advantages of natural cellulose source. The objective of this thesis was to develop a barrier packaging board based on MFC/NFC by coating processes.

Firstly, the study focussed on the characterisation of the MFC suspensions, on the manufacturing of MFC self-standing films and on the determination of their properties. Secondly, the development of MFC based composites was studied as model films. The last part was devoted to the introduction of MFC in coating colours in order to develop a barrier layer at the board surface. Trials at pilot scale demonstrated the industrial feasibility of this product. The potential of the use of MFC/NFC was demonstrated to be used as a drying additive and as a main component of barrier layer.
