Barrier, Mechanical and Thermal of Polyvinyl Alchol/Microcrystalline Cellouse Composites in Packaging Application

Abstract

In this study Polyvinyl alcohol (PVA) and (3, 5, 10%)wt microcrystalline cellulose (MCC) were prepared using a solution-casting method. The films that were produced characterized with Fourier Transform Infrared Spectrometry, Differential Scanning Calorimetric, Tensile test, and Barrier properties. The results from FTIR shows that PVA and MCC were considered miscible and compatible owing to hydrogen bonding interaction. Results for Thermal analyses increased in the glass transition temperature (Tg) thermal stability of polyvinyl alchol. Tensile strength of the films were increased with the increased loading of MCC to a composites films. Water vapor permeability of the MCC composites was increased with increasing with content of MCC in the films but oxygen transmission rate was decreased.
