Abstract
Packaging as one kind of composite product has been studied nowadays to be partially substituted with natural materials to improve its degradability in order to be environmental-friendly. Nanofiber cellulose derived from biomass has recently gained attention to be applied as composite filler prior to its biodegradable nature, low density, high mechanical properties, economic value and renewability. Nanofiber was prepared using pineapple (Ananas comosus) leaf waste as the raw material by acid hydrolysis using 64%wt H2SO4 in 40oC for 40 minutes. Nanocomposite film was produced by blending polyvinyl alcohol (PVA), cellulose nanofiber as filler and glycerol as plasticizer. The effect of varied nanofiber and plasticizer concentrations on the physical, mechanical and morphological properties of nanocomposite film was evaluated. Peak shown in FTIR graph would confirm acid hydrolysis in order to gain nano-sized fiber. The best formula selected aimed to be the most potential reinforcement selection in packaging composite film application
