“…Thermoplastic cassava starch was reinforced with cassava baggase cellulose nanofibrils [10]. Cellulose microfibrils from potato tuber cell waxy starch cellulose nanocrystals were also added to TPS films [2,11]. All results showed that the addition of cellulose nanofibers increases the mechanical performance of TPS films.…”

“…Starch consists of amylose and amylopectin. Amylose is a linear polymer consisting of -(1,4)-D-glucopyranose, while amylopectin is a highly branched macromolecule composed of both -(1,4) and -(1,6) glucopyranosyl linkages [2].…”

Thermoplastic starch-polyvinyl alcohol composite films were prepared by casting method with cellulose nanofibers as reinforcement agent and glycerol as plasticizer. The obtained cellulose nanofibers with a diameter of 27.23 ± 8.21 nm were isolated from oil palm empty fruit bunches (OPEFBs) by mechanical treatment. The addition of cellulose nanofibers until 3 wt% increased tensile strength and crystallinity of the composite films. In contrast, it decreased their elongation at break and water vapor transmission rate. Meanwhile, the addition of glycerol increased elongation at break and water vapor transmission rate of film matrix but lowers tensile strength of composite films.

“…As it is well known, when starch is mixed with an appropriate plasticizer in presence of water and heated to an appropriated temperature, the starch granules are disrupted and the crystalline domains are destroyed . This process, known as gelatinization, results in a material called plasticized starch (PLS) which could be a green candidate to substitute synthetic polymers in packaging applications . Thermoplastic starch (TPS) is obtained when a mechanical energy is also applied during the gelatinization, usually by extrusion.…”

In the present work, D‐isosorbide and 1,3‐propanediol are proposed as alternative plasticizers obtained from renewable resources. Plasticized starch films were prepared by solvent casting method. The influence of using different “green” plasticizers in the final properties of starch‐based films was analyzed. Besides, the characterization of the films was also performed after storage time in order to evaluate the effect of the plasticizer on aging. UV‐spectrophotometry results showed better optical properties for both glycerol and D‐isosorbide films with higher transparency. The thermal and mechanical properties resulted influenced by the nature of the plasticizer. It was demonstrated that water vapor permeability was governed by the starch‐water interactions, whereas the oxygen permeability depended on the plasticizer's nature. The storage time affected the surface, mechanical, and thermal properties of the plasticized starch films. Atomic force microscopy results concluded that the topography of the films changed due to aging. The use of D‐isosorbide as plasticizer reduced the evolution of the mentioned properties and enhanced the reliability of the material. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
