Biodegradable polymers for packaging material that can be substitute for petrochemical polymers

       In the past few decades, there is increases interest in the development of food packaging from biopolymer-based material. Consumers behaviour shows on increase inclination toward environmental friendly, biodegradable packaging material with prolong shelf–life during food preservation. The development of biodegradable polymers for packaging material that can be used as a substitute for petrochemical polymer is an interesting perspective that also provides an alternative to synthetic product will remain without decomposing for hundred, sometimes thousand and more focus in agriculture sources of income. Synthetic polymers are the most used materials and the environmental impacts caused by its accumulation in the environment are reasons for growing interest and investment of researchers in the development of alternatives to minimize these problems. The biodegradable  polymer much attention in the application of food packaging which  mainly responsible for antifungal properties  in order to improve nutrition, food safety, preserving the quality of food until consumption as well as to minimize chemical preservation and reduce environment impact. Biodegradable polymers are produced from natural polysaccharides, particularly starch, can be produced at low cost and on a large scale as well as their applications in food packaging and renewable raw materials therefore are easily decomposed in the environment, being an interesting alternative for the replacement of synthetic polymers. In addition, biodegradable films are a way of harnessing and adding value to waste materials in the food industry.Experimental results revealed that modified starch bionanocomposite film possessed high tensile strength, low film solubility, low water barrier property and high glass transition temperature. X-ray diffraction (XRD) indicate that there was an interaction and molecular miscibility among the major components while in Fourier transform infrared spectroscopy (FTIR) showed the hydrogen bonds was formed in between starch evaluated the possible interaction between major components and binder. The prepared bionanocomposite film can be useful in food packaging applications to improve the shelf life of products and safety and thus can replace the conventional plastic packaging materials.
