Physical properties of emulsion-based hydroxypropyl methylcellulose films: Effect of their microstructure

► We fabricated HPMC films with two droplet size distribution, but different oil content. ► Droplet sizes of dispersions influenced the microstructure of emulsified films. ► Stability of emulsions affected the surface microstructure of films. ► Physical properties of emulsified films were dependent on their microstructure. ► Surface properties were not correlated with vapor transfer of films.
