    The objective of the present study is to develop an inexpensive biodegradable film, which should have easy processability and acceptable mechanical strength. In the present study, glycerol was used as the raw material, which is the key to the development of cheaper biodegradable film since it is the byproduct of biodiesel. Many dicarboxylic acids were tested, including sebasic acid, oxalic acid, adipic acid, and maleic acid, by reacting with glycerol to make biodegradable materials. The preliminary results showed that the product of maleic acid reacting with glycerol performed best. Not only because it has better mechanical properties, but also the possibility to react through UV-curing process because of its double bond structure. The ability to combined thermo-curing and UV-curing process is crucial for mass production.
    This study also examined the peeling process and the introduction of water soluble release layer. By comparing polyvinyl alcohol (PVA), sucrose, corn syrup, and carboxymethyl cellulose (CMC), this study found that CMC performed best. This study demonstrated that it was possible to use self-synthesized biodegradable materials combined with water soluble release layer and slot die coating technology, to produce a cheaper and tougher biodegradable film.
