Effect of Plasticizer Type and Concentration on the
Type and concentration of plasticizer significantly (p < 0.05) affected the mechanical and barrier properties of the films. Sorbitol (SOR) plasticized films were the most brittle, with the highest tensile strength (TS, 3.14MPa) however its effect on water vapour permeability (WVP) was low (30.41g/mm/m2/d/kPa).
The Effect of Concentration and Type of Plasticizer on the
The Effect of Concentration and Type of Plasticizer on the Mechanical Properties of Cellulose Acetate Butyrate Organic-Inorganic Hybrids 143 be used as lower cost, partial replacement for a primary plasticizer. It is possible that a plasticizer used in one formulation as a primary plasticizer could be used in a second
Effects of plasticizer type and concentration on rheological
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.
Effect of plasticizer type and concentration on
On the contrary, density and water absorption of plasticized films decreased with increasing plasticizer concentration. Raising the plasticizer content from 15% to 45% showed less effect on the
Effect of plasticizer type and concentration on physical
In this study, sugar palm starch (SPS) films were developed using glycerol (G), sorbitol (S) or their combination (GS) as plasticizers at the ratio of 15, 30 and 45 (wt)% using casting technique. The addition of plasticizers to SPS film-forming solutions helped to overcome the brittle and fragile nature of unplasticized SPS films. Increased plasticizer concentration resulted to an increase in
- 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%.
- Does plasticizer concentration affect film performance?
- The results of the investigation showed that the gradual loading of plasticizers concentration (25%, 40%, 55%) enhanced the performance of the films according to the plasticizer type. The addition of plasticizer concentration increased the thickness, moisture content and water solubility of all films, irrespective of the plasticizer type.
- Does plasticizer affect physicochemical properties and stability of shellac films?
- The effects of molecular weight and concentration of plasticizer on physicochemical properties and stability of shellac films were investigated. Type of plasticizer was previously reported to have some effects on the stability of shellac films, and polyethylene glycol (PEG) was the plasticizer of choice for plasticizing shellac films.
- 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.
- Does plasticizer concentration increase W/W?
- (15%–45% w/w). The results show that increasing the plasticizer concentration from 15% to 45% 8.514 × 10 −10 g·s−1·m−1·Pa−1 for GS-plasticized films. The plasticized films exhibited increased WVP values regardless of plasticizer type.
- Does plasticizer type affect optical properties of bioactive edible films?
- The effects of plasticizers type and concentration on the optical properties of bioactive edible films were shown in Table 3. The result indicated plasticizer improved the opacity of chitosan/zein blend films, and the opacity of films was increased significantly (p < 0.05) with an increase of plasticizer concentration.
