聚酯薄膜是一种高分子塑料薄膜，因其综合机能精良而越来越遭到宽大花费者的青眼。因为我国现在的出产量跟技巧程度仍不能满意市场的需要，局部仍需依附入口。它是一种无色通明、有光芒的薄膜，机器机能精良，刚性、硬度及韧性高，耐穿刺，耐摩擦，耐低温跟低温，耐化学药品性、耐油性、气密性跟保香性精良，是常用的阻透性复合薄膜基材之一。

Polyester thin film is a kind of polymer plastic film, because of its excellent comprehensive function, it is more and more subjected to the green eye of the generous expenditure. Because China's current output and skill level still can not meet the needs of the market, part of it still needs to be attached to the entrance. It is a colorless, bright, shiny film with excellent mechanical functions, high rigidity, hardness and toughness, puncture resistance, friction resistance, low temperature and low temperature, chemical, oil resistance, gas tightness and fragrance. Excellent, It is one of the commonly used barrier composite film substrates.
