Abstract

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

包装用普鲁兰羧甲基纤维素共混膜的研制与表征

食用包装材料在制药工业中有着广泛的应用。在本研究中，研究了一种基于普鲁兰（PUL）和羧甲基纤维素（CMC）的新型食用膜的物理、热、颜色、机械和防水性能。采用溶液浇铸法，用3 g总固体含量。使用以下百分比100/0、75/25、50/50、25/75和0/100来制备膜。利用傅立叶变换红外光谱（FTIR）、X射线衍射（XRD）、扫描电子显微镜（SEM）和热重分析（TGA）分析了PUL与CMC之间的相互作用。在PUL的75/25%的水平上，CMC膜显示出最低的EAB%（5.55%），TS的最高值（17.30 MPa），WVP值（4.12×10−10 g m-1s-1Pa-1），水接触角为63.43°。随着CMC浓度的增加，共混膜呈微绿色和淡黄色，但呈现透明，具有紫外线阻挡能力。本研究表明，75/25（PUL/CMC）共混膜具有良好的潜力，可用于生产可食用包装膜，以保护具有有趣规格的药品的质量。
