Pullulan‐Based Films: Unveiling Its Multifaceted Versatility for Sustainability

This article explores the multifaceted potential of pullulan‐based films across food‐packaging, pharmaceutical, biomedical, and cosmetic applications. In food‐packaging, pullulan films serve as transparent, flexible, and high‐oxygen barrier materials, effectively preserving the freshness and quality of a wide range of fruits and vegetables. Edible pullulan films extend the shelf life and enhance food safety, while active pullulan films inhibit microbial growth and oxidation, thus supports food preservation. In the pharmaceutical industry, pullulan‐based films offer promising solutions for oral drug delivery, providing biodegradable and rapid disintegration for enhanced solubility and bioavailability of drugs. Additionally, due to their mechanical strength, biocompatibility, and antimicrobial properties, pullulan films demonstrate potential in wound dressings and tissue engineering applications. Furthermore, pullulan’s utility extends to the cosmetic industry, where it is used widely in various ingredients in skincare products, cosmetics, and personal care items. Its moisturizing, stabilizing, and film‐forming properties make pullulan an attractive component in the industry. Future research directions should focus on cost‐effective production methods and expanding industrial applications to further enhance their effectiveness and versatility. This in‐depth analysis highlights the significant potential of pullulan‐based films across multiple industries and underscores the importance of continued research and development efforts to fully unlock their diverse applications and benefits.
