Biodegradable films and pouches ("sachets") suitable for packaging pharmaceutical formulations, e.g., vaccines. The biodegradable films and sachets contain a top layer of cellophane, an adhesive layer, and a seal layer. These layers facilitate maintenance of active ingredient viability. The top layer includes cellophane for barrier protection, while the seal layer incorporates food-grade polybutylene derivatives. The films can be made into pouches by joining a front and a back composite material at a peripheral edge to form an internal compartment that encloses the pharmaceutical formulations. The biodegradable films are compostable in soil and safe for animal consumption. The biodegradable pouches are useful for vaccinating wildlife population, such as racoons.
