PET薄膜是一種性能比較全面的薄膜。其透明性好,有光澤;具有良好的氣密性;防潮性中等。PET薄膜的機械性能優(yōu)良,其強韌性是所有熱塑性塑料中最好的,抗張強度和抗沖擊強度比一般薄膜高得多;且挺力好,尺寸穩(wěn)定。PET薄膜還具有優(yōu)良的耐熱、耐寒性和良好的耐化學藥品性和耐油性。 PET film is a kind of film with comprehensive properties. It has good transparency and luster, good air tightness and moderate moisture resistance. The mechanical properties of PET film are excellent, and its strength and toughness are the best among all thermoplastics. The tensile strength and impact strength of PET film are much higher than those of ordinary film, and its stiffness is good and its size is stable. PET film also has excellent heat resistance, cold resistance, chemical resistance and oil resistance.
