Effect of glycerol plasticizer loading on the physical
Glycerol (G) was used as a plasticizer to investigate the effect of different glycerol concentration on AS films. The film making process mentioned below was referred to previous works of Sanyang
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
Effect of plasticizer type and concentration on physical
Increased plasticizer concentration resulted to an increase in film thickness, moisture content and solubility. On the contrary, density and water absorption of plasticized films decreased with...

Effect of Plasticizer Type and Concentration on Tensile
The type and concentration of plasticizer employed has significant effect on the physical, thermal, mechanical and barrier properties of films [ 35, 50, 51, 52 ]. The most common plasticizer utilized for starch based films are polyols such as glycerol and sorbitol, amongst many others.
- 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 increasing plasticizer concentration affect water absorption of plasticized films?
- 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 moisture content and water absorption of S-plasticized films.
- Does plasticizer concentration affect permeability of chitosan/Zein films?
- The permeability of films increased significantly with the increase of plasticizer concentration, but the C/ Z -P film (plasticized chitosan/zein film with PEG-400) had better barrier performance compared with the other two. The C/ Z -P film had better mechanical properties and light transmission.
- Does plasticizer type and concentration influence the properties of cassava-starch-based films?
- High contents of plasticizer resulted in changes in the properties of the films. Overall, it can be concluded that the plasticizer type and concentration significantly influence the properties of cassava-starch-based film.
- What happens if plasticizer concentration increases?
- Increased plasticizer concentration resulted to an increase in film thickness, moisture content and solubility. On the contrary, density and water absorption of plasticized films decreased with increasing plasticizer concentration.
- Does plasticizer type and concentration improve film properties?
- The results obtained in this study showed that plasticizer type and concentration significantly improves film properties and enhances their suitability for food packaging applications. Content may be subject to copyright.
