特点(Characteristics):
屏蔽袋的材质结构APET/CPP（半镀铝膜/聚丙烯流延薄膜）透明度好，手感硬，撕力比较弱与APET/CPE(半镀铝膜/聚乙烯薄膜)热封性好，撕裂度好，拉力强，手感比较软两种，整体颜色为银灰色半透明，内置物可见。
There are two kinds of shielding wrapper materials, one, its structure is APET/CPP, it is transparency, relatively hard, and its tear strength is relatively weak. The other one, its structure is APET/CPE, its seal is good, its seal is good, it has good tear and high tensile strength, and it feels soft. The overall color is silver-gray transparent, and the built-in objects is visible.
屏蔽袋独特的结构可形成感应罩效应保护袋内物品与静电场隔离，防止静电积累，免受静电危害，是防静电包装袋之首选。
The unique structure of shielding wrapper form a induction hood to effectively protect the goods inside the static field, from static hazards, and prevent accumulation of static electricity, is the first choice of Anti-static wrapper.
用途及应用领域（Use and applications）:
用于有防静电要求的电子产品包装，如各类PC板、IC集成电路、光驱、硬盘、电子元器件等。
The recommended use range of the shielding wrapper: electronic products packaging that has requirements for antistatic, such as various types of PC boards, IC integrated circuits, optical drives, hard drives and electronic components.
