A heat-shrinkable polyester film includes at least one polyester material made of at least one polyester forming composition which includes a dibasic carboxylic mixture and a diol mixture. The heat-shrinkable polyester film has a heat shrinkage rate of not lower than 25% in a shrinkage direction, which is measured by immersing the heat-shrinkable polyester film in hot water at 65° C. for 10 seconds. A method for producing the heat-shrinkable polyester film is also disclosed.

A composition in a water-in-oil-in-water (W/O/W) emulsion is disclosed. The composition comprises: (a) a continuous aqueous phase, comprising H.sub.2O; (b) an oil phase or an oil shell, dispersed in the continuous aqueous phase; and (c) a hydrophilic polymer, stabilizing an interface between the continuous aqueous phase and the oil phase or the oil shell to form the water-in-oil-in-water (W/O/W) emulsion. The oil phase or the oil shell comprises: (i) oil; (ii) an internal aqueous phase, dispersed within the oil or the oil shell; and (iii) a lipophilic sorbitan-polyester conjugate, stabilizing an interface between the oil and the inner aqueous phase to form a water-in-oil (W/O) emulsion. The lipophilic sorbitan-polyester conjugate comprises: (1) sorbitan; and (2) poly(lactide-co-ε-caprolactone) or polylactic acid (polylactide), conjugated to the sorbitan.
