PET背薄膜简介：

PET背膜是玻璃深加工行业对PET聚酯薄膜的简称。PET背膜又叫耐高温PET聚酯背膜，它是以聚对苯二甲酸乙二醇酯为原料，采用挤出法制成厚片，再经过双向拉伸制成的薄膜材料。

PET backing film is the abbreviation for the PET mylar used in the deep processing of glass.PET also called high heat-resistant PET mylar, it use polyethylene glycol terephthalate as the raw meterial,produce into thick film by squeezing,then draw at double sides.

PET背膜用途：

PET背膜主要应用于艺术写真强化玻璃、夹丝玻璃、夹层玻璃等单面强化玻璃中，用于替代一层玻璃，起到保护写真材料、夹丝材料以及玻璃背面的作用。

随着特种功能薄膜的开发，PET聚酯薄膜新的用途也不断出现。PET薄膜是一种性能比较全面的薄膜。其透明性好，有光泽，具有良好的气密性，防潮性，在低温下透湿率下降。PET薄膜的机械性能优良，其强韧性是所有热塑性塑料中最好的，抗张强度和抗冲击强度比一般薄膜高得多，且挺力好，尺寸稳定。PET薄膜还具有优良的耐热、耐寒性和良好的耐化学药品性和耐油性。汇丰玻璃科技供应的PET背膜是玻璃深加工工艺单面强化中首选的一种PET背膜材料。

The application of PET backing film

PET backing film mainly used in art strenghten glass,slim silk laminated glass etc one-side strenghten glass,to replace one layer of glass,to protect the drawing material,slim silk material and glass backing.

Along with the development fo functional film,the new function of PET mylar emerge.PET film have overall performance,good transparancy,vanish,good gas tightness,moisture will low in low temperature,good machenical performance,obdurability is the best among heating plastic material,higher tensile strength and resistance to impact,good rigidity,stable size,beside it gave excellent heat resistance,cold resistance,Chenical resistance,oil resistivity.The PET backing film provided by HuiFeng is the first opition for the glass deep processing industry.
