  • 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 do plasticizers affect the mechanical properties of a polymer film?
  • 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.
  • 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.
  • Do hydrophobic plasticizers affect aqueous biopolymer film permeability?
  • Although the addition of hydrophobic plasticizers decreases the water adsorption by film, at the same time, phase separation and development of discontinuous zones during drying of the film are a common problem in aqueous biopolymer film, which further increases the water vapor permeability of film (Bodmeier & Paeratakul, 1997).
  • Do plasticizers affect tensile strength?
  • Effect of plasticizers on tensile strength (TS) of HPMC/BW composite films composite films and formed more free volume. Therefore, they reduced the tensile strength (TS) and increased the elongation at break (EB). This explanation is also consistent with many studies when evaluating the effect of the same plasticizer on different biofilms.
