PVA-based Films in Medicine

PVA-based films in medicine are thin, flexible layers made from a biodegradable polymer called polyvinyl alcohol. They are used for controlled drug delivery, wound dressings, and medical coatings because they dissolve or release medication slowly when applied to the body. These films are biocompatible, meaning they are safe to use with human tissue, and can protect wounds, deliver drugs directly at target sites, or serve as temporary barriers. Their versatility and safety make PVA films valuable in modern healthcare for improving treatment effectiveness and patient comfort.
