“…The result of mechanical studies shows that the ternary blends have high tensile strength and high elongation at break which are better than that of binary PVA/starch and PVA/pectin blends 24,26,47 and might be used in food packaging and other applications in which high mechanical properties are required.…”

“…In nutshell, it may be inferred that tensile strength is mainly directed by the cross-linking effect, Young's modulus by plasticizing effect and % elongation by both cross-linking and plasticizing effects in the present study. The result of mechanical studies shows that the ternary blends have high tensile strength and high elongation at break which are better than that of binary PVA/starch and PVA/pectin blends 24,26,47 and might be used in food packaging and other applications in which high mechanical properties are required.…”

“…19,20 Also if the starch amount has been increased more than 25% then the tensile strength and elongation at break decrease very sharply as reported in the literature by Sin et al and Azahari et al 21,22 Blending of the PVA film with starch or pectin improved its biodegradability but reduce its barrier and mechanical properties (tensile strength and elongation at break). [23][24][25][26] Therefore, it is necessary to improve the packaging favorable properties of these composites with a fixed amount of PVA, for which the concept of ternary composites is more efficient to boost mechanical and other beneficial properties for food packaging. Also, study the effect of ternary combinations on the mechanical properties, thermal degradation, and biodegradation is in objectives.…”

The present study described reduces of plastic based non-biodegradable food packaging material and sustainability toward the environmental protection. The polyvinyl alcohol (PVA) based ternary blend biodegradable films with bio-materials (corn starch and pectin) in ratio 1:5, 1:2, 1:1 and 2:1 were synthesized by solution casting method in water as a solvent to improve the tensile strength, high % elongation at break, and sustained packaging properties. Citric acid and glycerol were used for cross-linking and plasticizing purposes which are also bio-degradable and non-toxic. Blend films were characterized by FTIR and checked out the cross-linking of different components. The dispersion of contents in films was analyzed by SEM images. Thermal stability and degradation behavior of casted films were studied with thermogravimetry and thermal stability increased in blends as compared to neat PVA film. Biodegradability of cast films was also checked by Soil Burial method and bio-degradation increased with time i.e. almost 50% degrades in 30 days and 68% after 90 days. Tensile properties of blend films were tested and found that tensile strength (18.85 MPa) and elongation at break (516%) are high in blend films as compared with neat PVA film (12.04 MPa, 170%). The films are eco-friendly and biodegradable, might be a replacement of plastic material in food packaging having improved tensile properties.

“…For example, a PVA/PEC blend was studied to evaluate the effect of PEC on the mechanical durability and water solubility of the film [14]. PEC was used as an additive in PVA membranes crosslinked with glutaraldehyde to study the mechanical properties of the obtained membranes [15]. Nanocomposite membrane were prepared by blending PEC with PVA crosslinked in-situ with a mixture of sulfosuccinic acid and glutaraldehyde [16].…”
