Formula: PHB
Form: Foil/Film/Sheet
Material: Polyhydroxybutyrate (PHB)
CAS Number: 29435-48-1
Commodity: Polymers
Thickness:
2mm
PHB Film offers excellent biodegradability, high crystallinity, and good barrier properties against moisture and gases, making it a sustainable choice for packaging, biomedical, and agricultural applications. Derived from microbial fermentation, polyhydroxybutyrate combines the functional stability of thermoplastics with environmental compatibility. Industries employ PHB film in compostable food packaging, biodegradable agricultural mulch films, and controlled-release drug delivery systems. Specific applications include eco-friendly wrapping for perishable goods, soil-biodegradable crop covers that reduce plastic waste, and polymer matrices for sustained pharmaceutical release. In research, PHB film is investigated for optimizing mechanical flexibility while retaining biodegradability, developing bio-based nanocomposites, and studying microbial degradation kinetics in various environments. Its balance of performance and sustainability positions PHB film as a critical material in green technology and circular economy strategies.
