The Preparation of Packaging Films from Ramie Based Carboxymethyl Cellulose

ABSTRACT

In this study, ramie fiber was used as the biomass material to prepare carboxymethyl cellulose (CMC). Additionally, the films were prepared by casting method using the ramie-based CMC, and the glycol was added as a plasticizer to overcome the fragility of the films. The films were extensively characterized using FT-IR, XRD, and TG&DSC. Moreover, the physicochemical characteristics and tensile properties of the CMC films were also evaluated. It was demonstrated that the CMC films prepared from ramie fiber with good film performances and better tensile properties which are suitable for packaging applications. This study provides a new way for value-added ramie fiber.

摘要

本研究以苎麻纤维为生物质原料制备羧甲基纤维素(CMC). 此外, 使用苎麻基CMC通过流延法制备薄膜, 并添加乙二醇作为增塑剂以克服薄膜的脆弱性. 使用FT-IR、XRD、TG和DSC对薄膜进行了广泛的表征。此外, 还评估了CMC膜的物理化学特性和拉伸性能. 结果表明, 由苎麻纤维制备的CMC膜具有良好的膜性能和较好的拉伸性能, 适合包装应用. 本研究为苎麻纤维的增值提供了一条新途径.
