Abstract
The present invention relates to a system for the compact packaging of microfibrillated cellulose, which comprises a packaging, which comprises at least one polymer material. Said packaging encompasses a content that essentially consists of microfibrillated cellulose (“MFC”) that is present as a suspension in a solvent. The resulting system is of an essentially round or essentially rectangular or oval outer circumference, as defined by the dimensions of the packaging once fully filled out by the content. The system of the invention has the advantage, among others, to provide a solid and firm essentially round packaging shape. The resulting units of packaged MFC can be easily stacked on a pallet. The packaging maintains the water retention capacity of the suspension (paste). The present invention also relates to a process for making such a system.
