Effect of Plasticizers on Mechanical and Barrier Properties
In general, films plasticized with glycerol and sorbitol displayed a better solubility in water than unplasticized films, i.e. 35% (w/w) glycerol and 45% w/w (sorbitol) (optimum solubility). The tensile strength of films decreased especially in the high concentration regime of plasticizers, between 20–45% (w/w) of plasticizer/rice starch film.
Effect of banana and plasticizer types on mechanical, water
A mixture of plasticizers (glycerol and sorbitol) showed high potential to improve long-term physical stability such as through UV–visible light prevention, and improved mechanical properties and heat sealability of plasticized banana-based films.

Effect of Selected Commercial Plasticizers on Mechanical
This paper explores the influence of selected commercial plasticizers structure, which are based on esters of citric acid, on mechanical and thermal properties of Poly(3-hydroxybutyrate)/Poly
Effects of Plasticizers on Mechanical Properties, Oxygen
Tensile strength and elastic modulus of films were decreased when adding plasticizers, whereas elongation at break were increased. Therefore, it caused an increase in oxygen permeability of...
- Do plasticizers soften thermomechanical properties?
- The effect of the different single-component plasticizers (glycerol, propylene carbonate and ethylene carbonate) on the mechanical and dynamic thermomechanical properties of the films were studied. Moreover, the softening effect of the two-component plasticizer based on deep eutectic solvents (DESs) was addressed.
- Does plasticizer affect bio-degradable rice starch-chitosan blend films?
- A completely randomized experimental design was used to study the plasticizer effect on the properties of bio-degradable rice starch-chitosan blend films. Analysis of variance (ANOVA) was used to determine the effect of plasticizer.
- Do biodegradable plasticizers affect thermal and mechanical properties of poly(PHBV)?
- The effects of biodegradable plasticizers on the thermal and mechanical properties of poly (3-hydroxybutyrate- -3-hydroxyvalerate) (PHBV) were studied using thermal and mechanical analyses. Soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were used as plasticizing additives.
- How do plasticizers affect tensile strength?
- Increasing concentration of these plasticizers resulted in decreased tensile strength (TS) concomitant with an increase in elongation at break (E), water vapor permeability (WVP) and film solubility (FS). SOR plasticized films were the most brittle, with the highest tensile strength (TS, 26.06 MPa).
- How does plasticizer concentration affect film solubility?
- Increasing the plasticizer concentration decreased TS with concomitant with an increase E, WVP and FS. Type and concentration of plasticizers affected the film solubility.
- Which Plasticizers improve elongation at break properties of biocomposites?
- HEC was used as a continuous matrix to introduce formability properties, whereas different plasticizers were studied to further improve the elongation at break properties of biocomposites. Glycerol, propylene carbonate and ethylene carbonate were studied as single-component plasticizers.
