Plastic pollutants are a significant environmental concern. Biodegradable plastics are a large area of research because if plastics are accidentally released into the environment, biodegradable plastics will break down into harmless byproducts. A blister pack is a type of packaging that consists of plastic pockets that hold individual pills. Current blister packs on the market are not biodegradable and contribute to environmental harm. The goal for this research project is to find an eco-friendly material to replace current blister packs that can also handle chemical reagents (such as medical reagents). Initial testing focused on developing a film from cassava starch that was adapted from the literature. The standard ASTM D543 was used to evaluate the resistance of the material to chemical reagents. The samples were placed under strain using a 3D printed strain jig, the chemical reagent was applied, and the samples were held at fixed temperature for varied amounts of time. After chemical exposure, the samples were tested to determine changes in mechanical properties. These results will be used to determine if cassava starch can replace traditional plastic blister packs to open the door to many environmentally friendly swaps in the medical field.
