Development and Characterization of Pullulan-Carboxymethyl Cellulose Blend Film for Packaging Applications

Edible packaging materials have widespread applications in pharmaceutical industries. In this study, the physical, thermal, colour, mechanical, and water barrier properties of a novel edible film based on pullulan (PUL) carboxymethyl cellulose (CMC) were investigated. The blend films made by solution casting method with 3 g total solid content. following percentages 100/0, 75/25, 50/50, 25/75, 0/100 used to prepare films. Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) analyze interaction between PUL CMC. At level 75/25 percentage PUL, CMC showed lowest EAB% (5.55%), highest values for TS (17.30 MPa), WVP value ( 4.12 × 10 − m-1s-1Pa-1), contact angle 63.43°. By increasing concentration, became slightly greenish yellowish but appeared transparent UV blocking ability. This study reveals that (PUL/CMC) has good potential can be producing protect quality products interesting specifications.
