“…XRD pattern of native corn starch granules showed diffraction peaks at 15.1°, 17.1°, 18°, 20°, and 23.1° which was semicrystalline materials with A‐type crystallinity [ 47 ] (Figure 2i). However, CSB composites only displayed distinct peak at 22.4° ascribed to (0 0 2) plane due to crystallinity loss of starch during thermal processing.…”

“…[ 54 ] That is because microorganisms can decompose polymers into compounds with small molecular weight through enzymatic hydrolysis, which leads to the degradation of natural polymers. [ 47 ] After 20 days, CSB 0 has largely degraded, while other samples could still maintain their original morphology. It was because adhesion interaction for CSB 0 was relatively weak without fiber integration.…”

The extensive use of nondegradable plastic tableware has brought serious environmental problems. Starch-based materials are good alternatives to plastics, but poor mechanical properties and intrinsic hydrophilicity limit their utilizations. In order to address this issue, naturally abundant bagasse pulp fiber is used as the reinforcing agent to improve the mechanical properties of starch and polydimethylsiloxane coating (CSB 35 -PDMS 50 ) to improve their hydrophobicity and hydrostability. CSB 35 -PDMS 50 reaches the tensile strength of 21.2 MPa and contact angle of 121°. The enhancement of the mechanical strength can be explained by strong hydrogen bonding between starch and cellulose, as indicated by noncovalent interaction-reduced density gradient (NCI-RDG) analysis. CSB 35 -PDMS 50 retains the low water adsorption rate within 60 h, remains stable in water for 24 h without morphology change, and maintains initial hydrophobicity after continuous abrasion in sandpaper and high-pressure water spraying due to the formation of Si─O-C bonds. The water absorption capacity of CSB 35 -PDMS 50 is less than 10% when used as the cap materials for Eppendorf tube for 30 days. Furthermore, CSB 35 -PDMS 50 demonstrates good biodegradability in the soil with 74% in 100 days. The tableware prepared from ther composites demonstrates good potentials as the competitive substitute for plastics with easy production, high strength, and biodegradability.

“…Among the agriculture product based (Exhibit 1) such as cassava starch, corn starch, potato starch, sugar palm starch, gum Arabic, sodium caseinate, wheat starch, and Janeng starch among the starch for bioplastics production (Saiful et al., 2019). Bioplastics made from starch are odorless, tasteless, colorless, and nontoxic (Ong et al., 2020). Nowadays, starch is available in form of physical and chemical modifications as natural starch is known to have high hydrophilicity of hydroxyl groups that can easily attract water and poor instability.…”

The application of petroleum-based plastic worldwide causes the accumulation of plastic waste in landfills, which negatively impacts the environment such as reducing the quality of soil and may cause soil and water pollution. Most of the conventional plastics used have a long lifespan to completely degrade. According to the rapid development of the food industry, plastic packaging plays a key role in food quality and safety, thus making it a major role in controlling the food security system. The alternative use of plastic sources from biopolymers is one of the methods to support environmental sustainability actions. This review provides an overview of studies on principles and challenges of sustainable packaging including different types of biopolymer compounds properties and biodegradability of bioplastics in soil by microorganisms. The biopolymers composition in biodegradable plastic is important in designing better mechanical, physical, and barrier properties during degradation by microorganisms and application in food industries.

In this work, carboxymethyl cellulose (CMC) with low substitution degree, followed by different posttreatments, was applied to prepare treelike CMC nanofibrils (CMCNFs) and rodlike CMC nanocrystals (CMCNCs), and their performance in CMC composite film was evaluated simultaneously. From transmission electron microscopy results, it was found that the treelike CMCNCFs exhibited a lager aspect ratio compared to the rodlike CMCNCs. As for reinforcing CMC film, 4 wt% was the best adding amount, at this time, the tensile strength of CMC/CMCNFs and CMC/CMCNCs composite films was increased by 72.1% and 47.3%, respectively. Moreover, adding these nanofillers to CMC also could enhance the thermal stability of composite films slightly, while the transmittance of composite films was reduced at the same time. In addition, CMC/CMCNFs film was designed as a packaging box to determine its performance. Therefore, this study could reveal the differences of properties for composites with different types of nanocellulose and provide a foundation for further application of nanocellulose.
