Biodegradable films based on rice starch and rice flour

Effect of Plasticizer Type and Concentration on Tensile, Thermal and Barrier Properties of Biodegradable Films Based on Sugar Palm (Arenga pinnata) Starch

“…In the case of GS-plasticized films, tensile strength reduction was observed from 15.82 to 3.99 MPa at the same range of plasticizer concentration. The decrease in tensile strength of starch based films as plasticizer concentration increased were reported by numerous authors [6,7,30,52,[58][59][60][61][62][63][64][65][66][67]. This phenomenon can be explained through the role of plasticizers in diminishing the strong intra-molecular attraction between the starch chains and promoting the formation of hydrogen bonds between plasticizers and starch molecules.…”

“…Thus, starch has attracted a great deal of interest as a potential alternative to conventional plastics for packaging applications. Several studies have investigated the development and characterization of starch based films from corn [4,[6][7][8], potato [9][10][11][12][13], cassava [14][15][16][17][18][19][20], banana [21], yam [22,23], pea [1], sago [24][25][26], rice [27][28][29][30], maize [31][32][33][34], Kudzu [35] and agar [36][37][38][39]. According to Sahari et al [40] sugar palm starch is also a potential biopolymer material for making biodegradable films.…”

“…The most common plasticizer utilized for starch based films are polyols such as glycerol and sorbitol, amongst many others. Several researches have been conducted regarding the effect of polyols (especially glycerol and sorbitol) on the properties of films based on various starch origins [10,[52][53][54][55][56][57].Of recent, Sahari et al [40,43] investigated the effect of glycerol content (15,20,30 and 40 w/w%) on the physical and thermo-mechanical properties of SPS. They concluded that 30 w/w% glycerol plasticized SPS exhibited better mechanical properties.…”

Characterization of thermoplastic starch/poly(lactic acid) blends obtained by extrusion and thermopressing

“…The parameter C, classically associated with the sorption heat of the monolayer, did not show different behavior for the samples and the magnitude of this parameter was consistent with values reported by other researchers for biofilms. 1,20,24 There were no significant differences in the value of k for the different blends studied. Since this parameter is related to multilayer sorption heat, it was consistent with the results obtained for the other parameters.…”

Preliminary study for acetylation of cassava bagasse starch and microfibrillated cellulose of bamboo

“…Furthermore, environment issue about replacement commercial plastics is harvesting by raising the demand bioplastic with renewable sources. Starch-based bioplastic have been employed several sources, such as banana [1], potato [2], sago [2][3][4][5], rice [6], corn [7], soybean [8], and cassava [9]. Cassava starch has been broadly utilized to be used in bioplastic reinforced with clay nanoparticles [9], thermoplastic chitosan [7], poly lactic acid [10], gelatin [11], bamboo nanofibrils [12], bacterial cellulose [13], and green coconut fiber [14] in order to overcome drawbacks of starch-based bioplastic, such as mostly water-soluble, low resitancy, and low mechanical property.…”
