Hydrogel film rolls provide certain benefits due to their characterized nature. Chemical, mechanical and thermal characteristics of chitosan make them good candidates for those applications such as wound healing & tissue engineering because of excellent biocompatibility and hydration. Due to their high-water content; the perfect place for cells and tissue to grow in order to regenerate. Hydrogel films could also be tailored for desired mechanical properties such as elasticity and strength in those applications where they need to provide mechanical protection or support. They also provide tunability of different material properties that can be customized for different types of applications, for mechanical properties in load bearing application or optical clarity in sensor application.
