Beschreibung
Zusammenfassung:	The present invention provides a shrinkable film comprising a polyester comprising certain combinations of a diol and a diacid in specific proportions. These polyesters provide certain advantageous properties in the resulting shrinkable films and are thus suitable as direct alternatives to commercially available shrink films made using poly (vinyl chloride). 本发明提供了包含聚酯的可收缩膜，所述聚酯包含特定比例的二醇和二酸的某些组合。这些聚酯在所得可收缩膜中提供某些有利的性质，并且因此适合作为使用聚(氯乙烯)制备的市售收缩膜的直接替代品。
