Application of Cellulosic Nano Crystals in Food Packaging Films

The term “Nano cellulose” generally refers to cellulosic material in the nanometer dimensions. Based on dimensions, performance and preparation methods, Nano celluloses are classified into three main groups: Nano crystalline cellulose (NCC), micro fibrillated cellulose (MFC) and bacterial Nano cellulose (BNC). Studies show that with the use of cheap and renewable raw materials, it is possible to produce high-performance coatings for common packaging materials. NCCs, which is easily obtained from hardwood, are capable of significantly inhibiting carbon dioxide and oxygen in the form of a thin coating on the films. Despite these advantages, interesting features such as mechanical and optical properties are also known that can be added to various packaging materials, such as antioxidant or antimicrobial agents. In certain cases, it has been used in the production of plastic film coatings.
