聚酯薄膜相比于其它塑料产品，拥有显著的物理性能、电气性能、光学性能和耐化学腐蚀性和可回收性。，明显的是它的耐热性和抗张强度，除此之外，它还拥有的阻气和防潮性能，很好的清晰度及化学稳定性。

   聚酯薄膜具有优良的物理、化学性质及尺寸稳定性、透明性、可回收性，可广泛的应用于磁记录、感光材料、电子、电气绝缘、工业用膜、包装装饰等领域，聚酯薄膜优异的的物理性能，使其适用于一般工业用途及作复合材料。

   聚酯薄膜由有机二元酸和二元醇缩聚而成的聚酯经纺丝所得的合成纤维。工业化大量生产的聚酯纤维是用聚对苯二甲酸乙二醇酯制成的，中国的商品名为涤纶。是当前合成纤维的大品种。所有不会对人体产生危害。

Compared with other plastic products, polyester film has remarkable physical properties, electrical properties, optical properties, chemical corrosion resistance and recyclability. , it is obvious that its heat resistance and tensile strength, in addition, it also has the resistance to gas and moisture, good clarity and chemical stability.

Polyester film has excellent physical and chemical properties, dimensional stability, transparency and recyclability, and can be widely used in fields such as magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, etc. The excellent physical properties of polyester film make it suitable for general industrial applications and as composite materials.

Polyester film is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic diacid and diol. Industrial mass production of polyester fiber is made of polyethylene terephthalate, China's trade name is polyester. It is a large variety of synthetic fiber at present. All will not cause harm to human body.
