The primary objective of this study is to make a product for packaging that combines the better characterstics of plastics and paper. durability and degradability. In the process, the cost is reduced and nonbiodegradable products are recycled. The researchers utilized styrofoam as a source of polystyrene, which was used to coat the papers. The coated papers were tested for their durability using breaking stress test. The water absorbency and reaction to common substance of the product were also tested. Results showed that thepolystyrene-coated paper exhibited greater breaking strength than the uncoated paper. They were more waterproof and unreactive to hydrochloric acid and sulfuric acid.
