“…The higher tensile strength value resulted from the higher energy required to deform the angles and distances of the bonds between the atoms of the polymer chain. This energy was generated by the positive interaction of starch and CMC elements, specifically starch OH and CMC-COOH [21]. The type of starch source, starch content, and additives such as plasticizers and fillers all have an impact on how well tensile strength in bioplastics demonstrates its properties.…”

The general public uses plastic extensively, particularly in food packaging. Plastic raw materials are generally petroleum derivatives with advantages such as high tensile strength, low cost, lightweight, ease of manufacture, and application. However, there are other disadvantages to plastic, which is not easily biodegradable. As a result, researchers have expressed a strong desire to develop biodegradable plastics in order to reduce the accumulation of non-biodegradable plastics in the environment. One of the candidates for producing bioplastic using natural resources is biodegradable plastics. Bioplastics based on starch are a common material used in the production of bioplastics. However, because bioplastics have lower tensile properties than conventional plastics, fillers are used to increase the strength of bioplastics. Fillers are used to reduce plastic cost, shrinkage during the setting process, and to improve tensile strength and hardness. As a result, the tensile and morphology of several starch-based biodegradable plastics with chitosan, CMC fiber, and clay as fillers will be reported in this review. According to our mini-review, sorbitol and CMC are very good plasticizers for starch-based bioplastics, and CMC has a higher crystallinity form, promoting greater interaction between the cellulose chains and starch-based matrix.

In this study, the effect of cellulose as a reinforcement agent and different ratio of glycerol/sorbitol as plasticizers to improve properties in starch biocomposite are optimized with Design-Expert method for the first time. Thermoplastic starch granule is produced with plasticized and cellulose-reinforced starch by a twin extruder. After conditioning, the starch granule, is molded into sheet using a hot press with thick plates. Dynamic mechanical thermal analysis show that cellulose increases the glass transition temperature to 120°C. Optimum point of the starch composite obtained by Design-Expert software 7.1.5, is run with 5 wt% cellulose, 17.5 wt% glycerol and 17.5wt% sorbitol that has water vapor permeability value equally of 7.81E-10g s −1 m −1 Pa −1 , tensile strength of 0.85 MPa, Young´s modulus equally of 377.65 MPa, and elongation at break of 7.08%. Field emission scanning electron microscopy of the optimized biocomposite shows uniform distribution of cellulose in the matrix. Hydroxyl stretching vibrations at 3286 cm −1 is a result of new hydrogen bonding between cellulose and starch molecules and peaks at 3366 and 1702 cm −1 are attributed to glycerol and sorbitol, respectively in the Fourier transform infrared spectra.
