Abstract

The application of cellulose nanofibers in the food packaging industry, mainly due to increased demand for product health and safety, shelf-life extension, cost-effectiveness, environmental and consumer comfort, during Recent years have expanded significantly. In order to better handle packaging to meet these different demands, innovative and controlled packaging materials have been developed and optimized for commercial application potential. Recently, these materials have largely been derived from fossils extracted from plastic derivatives, but due to increasing environmental considerations, materials from renewable sources have been widely considered as a potential alternative. These materials must have the same shelf-life satisfaction as the products derived from petroleum products to protect the products offered. In fact, proper materials must have sufficient mechanical properties, and provide sufficient protection against oxygen, water vapor, light, microorganisms, and other contaminants to prevent food from spoiling. Wheat straw is one of the most important agricultural waste for the production of cellulose nanofibers. The results showed that the tensile strength and burst strength of the optimum cellulosic nanofilms produced for use in wheat straw by microfluidizer were 119/86 nm / g, 8.5 kpa / g, respectively. The results of this study showed that since this material is a kind of agricultural waste and is of little value and use and of course a considerable amount is available, it can be said to be a good raw material for the production of cellulosic nano-fibers.
