Initial Properties Identification of Refined- and Semi Refined-Carrageenans as Raw Materials for Biodegradable Plastic Production

Powdered refined- and semi-refined carrageenans (RC SRC) have been characterized as alternative raw materials for industrial bioplastic production. Several basic parameters, i.e., the melting temperature, crystallinity, chemical structure (FTIR), tensile properties, were observed. The temperature of RC was slightly higher than that SRC, 176 °C 172 °C, respectively. These temperatures corresponded to their crystallinity degree (performed by X-ray diffraction). Nonetheless, SRC demonstrated an overall thermal stability during heating. produced a clear transparent film. Meanwhile, yellowish less transparent. mechanical properties showed more flexible film SRC. However, both relatively equal strength. In general, could be potentially used biodegradable production with different applications. suitable plastic film, whereas rigid
