Effect of plasticizers on the barrier and mechanical
A similar effect on the mechanical properties was observed as for the pure polymer, that is, even at a very low (12%) final concentration, the ionic liquid was a better plasticizer than glycerol, being able to double the ductility of the composites.

Comparative Effect of Different Plasticizers on Barrier
The addition of plasticizers affects the mechanical properties and WVP of a polymer film by altering the intermolecular interaction of polymer; also, the added plasticizers alter the moisture sorption behavior of resulting films which is an important factor in deciding the stability of edible film/coating.
Effect of glycerol plasticizer loading on the physical
Due to magnificent versatility, mechanical and barrier properties, petroleum-based plastics mostly have wide applications in packaging industries 4,5,6,7. Even though petroleum-based plastics have
Influence of plasticizers on the mechanical and barrier
The structural, mechanical, and barrier properties to water vapor and oxygen were characterized in order to study the effectiveness of the plasticizers and their respective influence on the film properties. The mechanical results show there was a plasticizing effect with all the plasticizers, but the influence on the barrier properties depends
- Do plasticizers affect mechanical and barrier properties of rice starch film?
- The effect of plasticizers, glycerol, sorbitol and poly (ethylene glycol) 400 (PEG 400), on mechanical and barrier properties of rice starch film has been investigated. Sorbitol- and glycerol-plasticized starch films appeared homogeneous, clear, smooth, and contained less insoluble particles compared to unplasticized rice starch films.
- 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.
- How does the type of plasticizer affect biopolymer properties?
- The type of plasticizer can strongly affect the barrier properties, water uptake, and mechanical properties of the biopolymer.
- Do plasticizers affect alginate-based films?
- Some reviews on the effect of plasticizers are about improving the flexibility of the most common biopolymers such as PLA and starch [10, 11], but there is no dedicated article focusing the effect of plasticizers on alginate-based films, in particular.
- Do plasticizers affect oxygen permeability?
- As a result, for each plasticizer, the composite oxygen permeability tends t o be different. Glycerol film shows the best oxygen barrier property, PG film experiences a moderate OP values, and PEG 400 film has the highest OP values. These results is consistent with other reports on the effect of plasticizers types on natural – based films.
- Do plasticizers increase tensile strength and elongation at break?
- HPMC/BW composite films incorporated with 2% of plasticizers formed films with the best characteristics among three tested concentration. Tensile strength and elastic modulus of films were decreased when adding plasticizers, whereas elongation at break were increased.
