    • The present invention is a polyester film obtained by blending 10-90 wt % of polyester (A) containing ethylene terephthalate as a main constituent component and 90-10 wt % of crystalline polyester (B) different from this polyester (A), which has a half value width of a recrystallization peak obtained by a differential scanning calorimeter (DSC) by lowering temperature of not more than 0.25. The crystalline polyester (B) is preferably a polyester selected from polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT) and polyethylene 2,6 naphthalate (PEN). According to the polyester of the present invention, a polyester film superior in mechanical characteristic and design property and having high crystallinity, which can be used alone or adhered to a metal sheet and which is free of whitening even when the film is heat treated at near or not lower than the melting point can be obtained, and further, a polyester film having such superior resistance to whitening (design property), which is not easily damaged, can be obtained.
    • 本发明是将10-90重量%的含有对苯二甲酸乙二醇酯作为主要成分的聚酯(A)和不同于该聚酯(A)的90〜10重量%的结晶性聚酯(B) 通过差示扫描量热计(DSC)通过降低温度不大于0.25获得的再结晶峰的半值宽度。 结晶性聚酯(B)优选为选自聚对苯二甲酸丁二醇酯(PBT),聚对苯二甲酸丙二醇酯(PTT),聚萘二甲酸乙二醇酯(PEN)等的聚酯。 根据本发明的聚酯,具有机械特性和设计性能优异且结晶性高的聚酯膜,其可以单独使用或粘附到金属片上,即使在近乎热处理的情况下也不会发白 或不低于熔点,此外,可以获得不易损坏的耐美白性(设计性)优异的聚酯膜。
