Effect of Plasticizer Type and Concentration on Tensile
The effect of different plasticizer types (glycerol (G), sorbitol (S) and glycerol-sorbitol (GS) combination) with varying concentrations (0, 15, 30 and 45, w/w%) on the tensile, thermal and...
Effect of Plasticizer Type and Concentration on Tensile
The tensile strength of G-plasticized films notably decreased from 9.59 to 1.67 MPa and that of S-plasticized films dropped from 28.35 to 5.84 MPa as plasticizer concentration increased from 15% to 45%. In the case of GS-plasticized films, tensile strength reduction was observed from 15.82 to 3.99 MPa at the same range of plasticizer concentration.
Effect of plasticizer type and concentration on the tensile
As anticipated, the increase of plasticizer concentration from 15% to 30% registered considerable increase in film elongation: 26.52%–61.63% for G-plasticized films, 5.38%–34.5% for...
Effect of Plasticizer Type on Tensile Property and In Vitro
The effect of plasticizer concentration (20–40%) on the Young’s modulus values of pectin plasticized films was shown in Figure 2 c. Young’s modulus values regularly decreased with the addition of plasticizer content, meaning that LMP films lost their stiffness and became more flexible with the addition of the plasticizer. Among the
Effects of plasticizer type and concentration on the
Physical properties of edible film from squid Todarodes pacificus mantle muscle plasticized with different plasticizers (glycerol, sorbitol, glucose, and fructose) at various concentrations (10%, 20%, and 30% w/w of protein) were determined. The results showed that tensile strength (TS) significantly decreased (P < 0.05) while elongation at break significantly increased (P < 0.05) upon
- Do plasticizers affect film tensile strength?
- The anti-plasticization effect of plasticizers on starch based films depends on their concentration level [14,79,80]. The stress–strain curves in Figure 3 clearly shows the decrease of film tensile strength and increase of flexibility as plasticizer concentration increased.
- Does plasticizer concentration affect thermal properties of s-plasticized films?
- Change in plasticizer concentration showed an insignificant effect on the thermal properties of S-plasticized films. The glass transition temperature of SPS films slightly decreased as the plasticizer concentration increased from 15% to 45%.
- Do different plasticizer types affect mechanical and thermal properties of LMP films?
- The effect of different plasticizer types (glycerol: Gly; sorbitol: Sor; propylene glycol: PG; and polyethylene glycol 300: PEG 300) and concentrations (20–40% w/w) on mechanical and thermal properties of LMP films as well as on in vitro release of indomethacin were evaluated.
- Does plasticizer type affect tensile strength of SPS films?
- Effect of plasticizer type and concentration on the tensile strength of SPS films. level [14,79,80]. The stress–strain curves in Figure 3 clearly shows the decrease of film tensile strength and increase of flexibility as plasticizer concentra tion increased.
- Does plasticizer type affect tensile strength of sugar palm starch films?
- Effect of plasticizer type and concentration on the tensile strength of sugar palm starch (SPS) films. counterparts at a constant plastici zer concentration. For example, the tensile strength values of G-plasticized films at 15%, 30% and 45% plasticizer concentrations, respectively. These results are at constant proportions.
- Does plasticizer type affect chitosan/Zein film rheological and structural properties?
- The chitosan/zein film with PEG-400 exhibited superior properties. The purpose of this study was to evaluate the effect of plasticizer type (glycerol, PEG-400, and sorbitol) and concentration (0%, 15%, 30% and 45%, w /w dry polymer weight) on rheological and physico-mechanical and structural properties of chitosan/zein blend film.
