- Abstract
The development of synthetic polymers makes profit for industry but creates some serious environmental problems. Due to environmental concerns, various biodegradable polymers are used by industries for different applications. These polymers are used as a replacement of synthetic polymers. They are obtained from nature and used as an overflow material for solid waste system. Nowadays, SPI is mostly used as a biodegradable polymer in plastic indutsries due to low cost and easy availability. It is obtained from plants and primarily utilized by food industry for packaging applications. Recently , it is frequently utilized as a prime material for preparation of various products such as containers, trays, fibers, and packaging material. The present work represents the preparation of SPI/PVA biocomposite thin films via solution casting method. These films were investigated for their thermal, mechanical, and morphological properties. The structural properties were performed by XRD and FTIR. The tensile strength and the thermal stability of the prepared biocomposites were reduced due to inclusion of SPI in PVA film. The surface morphology revealed the information of uniform dispersion and roughness of SPI molecules onto the surface of PVA matrix. The aim of this paper is to prepare SPI/PVA biocomposite for packaging applications.
