Natural-based plasticizers and biopolymer films: A review
The effect of polyols such as GLY, EG, PEG and PG on mechanical and surface properties of chitosan films was evaluated considering the plasticizer volatility [36], since it may influence film properties and stability during application and storage, i.e. the less volatile the plasticizer, the better it is for use. Besides, considering the
Plasticizer effect on the properties of biodegradable blend
The properties of biodegradable blend film from rice starch-chitosan with different plasticizers were determined. Three plasticizers comprising sorbitol (SOR), glycerol (GLY) and polyethylene...
Plasticizer effect on the properties of biodegradable blend
chitosan biodegradable blend films showed a logarithmic increase at above 0.59 a w and reached the highest moisture content of 51.46% and 42.97 % at 0.95 a w, whereas PEG rice starch-chitosan biodegradable blend films did not show much increase in moisture content.

Effects of plasticizer/cross-linker on the mechanical and
Biodegradable blends of potato starch and polyvinyl alcohol were prepared by solution casting method. Citric acid was employed to introduce the plasticizing effect into the starch materials. Glutaraldehyde as cross-linker was used to enhance the properties of the blend films.

- 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 plasticizers affect the functional properties of biodegradable gelatin-based films?
- Thus, addition of plasticizers into the film materials improves the functional properties of films by increasing their extensibility, dispensability, flexibility, elasticity, and rigidity. This study aims to review the current findings on how plasticizers impact the functional properties of biodegradable gelatin-based films.
- Does a plasticizer affect the color of biodegradable blend film?
- The color of biodegradable blend film from rice starch-chitosan was more affected by the concentration of the plasticizer used than by its type. Nine moisture sorption models were applied to experimental data. Moisture content of the film increased at elevated water activity.
- Why do biodegradable films need a plasticizer?
- A major compo-nent of biodegradable films is the plasticizer, as well as the film-forming polymer. The addition of a plasticizer agent to biodegradable blend films is required to overcome film brittleness, caused by high intermolecular forces.
- 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.
- What are biodegradable plasticizers?
- Biodegradable plasticizers such as soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were added to poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films, enhancing their thermal and mechanical properties. TEC or DBP presented better plasticizing effects than SO and ESO for PHBV .
