Summary: In order to replace a nonbiodegradable sealing film, a flexible, hydrophobic, and multilayered poly(vinyl alcohol) (PVA) film was developed. Eco-friendly fillers such as cellulose nanocrystals (CNCs) or cellulose nanofibers (CNFs) were added to enhance the mechanical properties of PVA. Biodegradable and hydrophobic materials like poly(ethylene glycol)-poly(lactic acid) (PEG-PLA) and neat PLA were incorporated to form multilayered PEG-PLA and PLA hydrophobic composites. The resulting PVA film exhibited superior transparency, mechanical properties, and hydrophobicity compared to a commercially available sealing film.
