Microfibrillated cellulose can also be used as aluminum replacement in packaging applications

A repeating unit of glucose makes up the cellulose polymer, a naturally occurring linear polymer. The cellulose fibre structure found in nature is made up of single polymers that are stacked together to create fibrils, and these fibrils are then stacked together once more. With both crystalline and amorphous sections, this results in a really intriguing supramolecular structure.

The process of fibrillating cellulose fibres yields microfibrillated cellulose (MFC). The cellulose fibres are cut apart into a three-dimensional network of microfibrils with a substantial surface area via mechanical shearing. The resultant fibrils can create a network or web-like structure, as shown in the image below, and are much smaller in diameter than the initial fibres.

A natural substance known as microfibrillated cellulose (MFC) is composed of cellulose fibrils that have been removed from a source, such as wood pulp. Increased tensile strength, better barrier characteristics, smoother surfaces, and other advantages can result from the addition of MFC fibres to the paper-making process. MFC fibres link together and create strength.
