In this modern era, pharmaceutical scientist throughout the world is trying to explore thin films as a novel drug delivery tool. In different sectors like pharmaceuticals, food industry, papers, textiles etc., have abundant use of polymers but in recent time biopolymers are being mostly used rather than the synthetic non-biodegradable polymers.
There are many natural polysaccharides studied so far, Starch is one of them. It is considered as the richest renewable biomaterial to produce different pharmaceuticals product or food product. It has been used in various applications like edible film, biodegradable films, pharmaceutical emulsion etc. It is due to its low cost, easy-tailoring, bio-compatibility, renewability, and other interesting performances. It has been evident that native starch has numerous limitations including but not limited to water resistance, weak tensile strength, etc. So, there is need of modification of native starch to enhance the properties characteristic. Furthermore, literature suggested that starch can be modified with varieties of methods such as physical, chemical, or different enzymatic methods, which certainly have their impacts on film forming properties. Increased paste clarity, gel and paste textures, and film forming ability of modified starches have improved with these techniques.
The increasing use of modified starches in edible and biodegradable films has been supported by their good film-forming capacities, which have a wide range of applications such as pharmaceutical coating, fruit coating, and packaging materials.
