Soy protein isolate (SPI)/kapok husk (KH) based biofilms were prepared by casting method. The effect of phthalic anhydride (PA) content on tensile properties and morphology were studied. The PA was use as a crosslink agent. It was found that the increasing PA content have increased the tensile strength and modulus of elasticity of biofilms, whereas the elongation at break decreased. At 1.5 % of PA showed the highest tensile strength and modulus of elasticity of crosslink biofilms. The morphology study indicates the crosslinking with PA improved the interfacial interaction between KH and SPI matrix.

With soy protein isolate (SPI) as the main raw material, and ethylene glycol (EG) and polyethylene glycol (PEG) as two additives, a number of SPI-based films were prepared through the solution casting method. Results show that the film flexibility is obviously improved after adding EG and the film tensile strength and elongation at break could reach more than 10.5 MPa and 140%, respectively. The antimicrobial results exhibit EG has higher antibacterial effect against both bacteria ofE. coliandS. aureusthan PEG-400.

Nowadays bioplastics is the most recent study materials as the substitute for conventional plastics. The interest in bioplastics has lead to the production of polylactic acid (PLA) biocomposite films. In this study the PLA/Corn husk (CH) biocomposite films were prepared by using solvent casting method and the effect of CH content on the tensile properties were studied. The result found that increasing of CH content decreased the tensile strength and elongation at break of the biocomposites film. While, the modulus of elasticity increased with the increasing of CH content in the PLA matrix.

The mechanical properties difference between soy protein isolate-based film and whey protein-based film was researched. The elongation at break, tensile strength of the pure soy protein isolate film both are better than that of the pure whey protein concentrate film, which is respectively 10 times and 25 times. After compounding the property of the whey protein concentrate film ameliorates. The elongation at break, tensile strength of the whey protein concentrate film increases respectively by 9 times and 16 times after the glutin is mixed. The elongation at break, tensile strength of the whey protein concentrate film increases by 1.1 times and 12 times after the chitosan is added.

This research focused on the utilization of kapok husk (KH) as filler in low linear density polyethylene (LLDPE). The effect of filler content on tensile properties and morphology of LLDPE/KH eco-composites were investigated. The eco-composites were prepared by using Brabender Plasticiser EC Plus at temperature 160 °C and rotor speed 50 rpm. The results indicated that the tensile strength and elongation at break decreased with KH content increased. However, the modulus of elasticity increased with increasing of KH content. The morphology study of eco-composites exhibit poor interfacial adhesion between KH and LLDPE.

This paper explains and demonstrates the effects of beeswax on functional and structural properties of soy protein isolate films, containing different glycerol. The results showed that percentage elongation at break, water vapor permeability, and transparency of soy protein isolate films decreased when the beeswax content increased, but tensile strength and oxygen permeability increased. The higher the glycerol content, the higher the film water vapor permeability, oxygen permeability, and transparency. The results of differential scanning calorimetry and Fourier transform infrared spectroscopy suggested that beeswax cross-linked with soy protein isolate molecules via connecting with glycerol, composed the film matrix.

The aim of this study is to produce PLA nanocomposites by solvent casting incorporating Montmorillonite nanoclays (MMT) and titanium dioxide (TiO2) nanoparticles. The effects of difference loadings of MMT in PLA and different loadings of TiO2 on mechanical and morphology properties were studied. The nanocomposites were prepared by solvent casting at different loadings of MMT (0, 2, 4, 6 and 8 wt %) and different loadings of TiO2 (1 and 3 wt %) respectively. The properties such as tensile properties (tensile strength, elongation at break, and modulus of elasticity) and morphology were determined. The results indicate that 4 wt% of MMT loading produced the best tensile properties. However, the incorporation of TiO2 showed an improvement in the modulus of elasticity of PLA/MMT nanocomposites mainly at 1 wt % loading of TiO2.

Polymer blending is one of the methods used to improve some insufficient properties of conventional polymers. The objective of this work was to study the effectiveness of CR content on the tensile properties and morphology study of recycled polypropylene (rPP)/ chloroprene rubber (CR) blends. The results indicated that the tensile strength and modulus of elasticity of rPP/CR blends decreased, however elongation at break increased as increasing CR content. The morphology study of rPP/CR blends showed the incompatibility between rPP and CR with the detachment of CR particles and CR particles pulled out from rPP surface.

Purpose: The aim of this study is to examine the potential of Cellulose Nanofiber(CNF) isolated from the banana peel through chemical treatment(Alkaline Treatment, Bleaching and Acid Hydrolysis) as reinforcing agent in Soy Protein Isolate films. It also aims to find an application for this agro-industrial residue as a biodegradable material for food packaging. Study Design: Experimental Design. Materials and Methods: Chemicals such as Sodium metabisulfite, Ethanol, Potassium hydroxide, Sodium hypochlorite, Acetic Acid, Sulfuric acid, Glycerol, Sodium Hydroxide, and Hydrochloric Acid were bought from a chemical depot. FTIR Spectroscopy, SEM Imaging, Tensile Strength Test, Dimensional Stability to Heat Test were performed. Results: The results of the tests conducted(FTIR Spectroscopy, SEM Imaging, Tensile Strength Test, Dimensional Stability to Heat Test and Stability in Acidic and Alkaline Conditions Test) showed that CNFs isolated from the banana effectively reinforced the properties of Soy Protein Isolate films. Furthermore, the films fabricated are still biodegradable, displaying that the addition of the CNF does not have any significant effect on the biodegradability of the films. Conclusion: It is concluded that the addition of Banana Peel CNFs as retrofitting material to the Soy Protein Films materially strengthen the mechanical properties of the films and makes it more suitable for food packaging applications.
