新产品珍珠棉复PE膜


      这是一种具有缓冲减震性能的环保包装材料.具有双层材料结构,表层为:HDPE;内层为:LDPE,EPE,又称可发性聚乙烯;它采用滑石粉,单甘油脂,丁烷发泡成型,整个生产过程为物理变化,所以无毒,环保。加入抗静电性能。表面电阻值为:108-1011Ω。该袋由珍珠棉和PE膜通过热封性复合而成,可根据客人要求制成卷料,片材或者袋子。

      它柔韧,质轻,富有弹性,通能过弯曲来吸收和分散外来的撞击力,达到缓冲的效果。主要用于精密电子元器件,电子通讯设备,汽车零部件,家具,医疗设备,易碎品等的包装。同时,EPE还具有保温,防潮,隔热,防摩擦,耐腐蚀等一系列优越的使用特性。

PE-film-coated EPE foam bag

This is an environmentally friendly packaging material with cushioning and shock absorption performance.It has two layers,The outer layer is HDPE;the inner layer is LDPE,EPE,which is also called as epispastic polyethelene.It adopts the epispastic molding of talc powder,glyceride,butane,etc.and the whole process is only a physical change.Therefore,it has no toxin and is environmentally friendly,The EPE material added twith antistatic agent has prominent anti-static property with a surface resistance of 108-1011Ω The material made through the thermal sealing lamination of pearl sponge,PE film  can be made into coiled film material,sheet material or bag according to the requirements of customers.

It is soft,light and flexible,Through bending it can absorb and disperse the external impact force to achieve the cushioning effect It ismainly applicable to the packaging of electronic component,electronic communication equipment,auto part furniture,medical equipment,fragile article etc,Meanwhile,the EPE has a series of superior application characteristics,such as heat preservation,moisture barrier heat insulation,friction resistance,and erosion resistance.
