屏蔽袋铝箔袋的品质怎么区分比较好？

防静电屏蔽袋通常用于电子组件的包装，以防止电子组件容易发生的静电发电所造成的损害。通常，防静电屏蔽袋采用二层复合或更高的四层结构。袋里形成法拉第笼感应罩效应，[敏感词]保护袋内物品与静电场隔离，防止静电积累，免受静电危害。

Anti static shielding bags are usually used for packaging electronic components to prevent damage caused by static electricity generation that is prone to occur in electronic components. Usually, anti-static shielding bags adopt a two-layer composite or higher four layer structure. The Faraday cage induction cover effect is formed inside the bag, which protects the items inside the bag from the electrostatic field, prevents static accumulation, and prevents static electricity hazards.

防静电屏蔽袋采用二层或四层复合：（VMPET/CPE或PET/AL/NY/CPE），具有优良的防静电、防射频、防水蒸汽渗透、防盐雾等诸多功能，还有屏蔽外部人员、设备的ESD静电放电及外部电磁辐射性能。适用于PCB、IC等静电敏感类高科技电子产品的运输与包装。

The anti-static shielding bag adopts two or four layer composite (VMPET/CPE or PET/AL/NY/CPE), which has excellent anti-static, radio frequency, waterproof steam penetration, salt spray and other functions. It also shields external personnel and equipment from ESD electrostatic discharge and external electromagnetic radiation performance. Suitable for the transportation and packaging of static sensitive high-tech electronic products such as PCBs and ICs.

屏蔽袋具有优良的防静电、防射频、防水蒸汽渗透、防盐雾等诸多功能。它们独特的四层结构可形成“感应罩”效应以保护袋内物品与静电场隔离．另外里面一层是由可静电乙烯组成，防静电功能优越。防静电屏蔽袋材料内外层由透明的防静电材料构成，中间为半透明的导电金属层，因而具有良好的防静电、静电屏蔽性能。

Shielding bags have many functions such as excellent anti-static, anti RF, waterproof steam penetration, and anti salt spray. Their unique four layer structure can form an "induction cover" effect to protect the items inside the bag from the electrostatic field. In addition, the inner layer is composed of ethylene that can eliminate static electricity, with superior anti-static function. The inner and outer layers of the anti-static shielding bag material are composed of transparent anti-static materials, with a semi transparent conductive metal layer in the middle, thus having good anti-static and electrostatic shielding performance.

1、袋子的用料：

1. Bag material:

铝箔袋需要无异味。有异味的袋子一般让人觉得不符合卫生标准，还可能会影响袋子的正常使用。如果没有异味，需要检查袋子的透明度，清晰度是否均匀、否有杂质感等等。

Aluminum foil bags need to be odorless. Bags with odors generally make people feel that they do not meet hygiene standards and may also affect their normal use. If there is no odor, it is necessary to check the transparency of the bag, whether the clarity is uniform, and whether there is any sense of impurities, etc.

2、印刷质量：

2. Printing quality:

看两种颜色的拼接处是否有明显的第三色，实物图的逼真水平越高越好，看看是否有拉丝、雾版、堵版、漏印等现象。

Check if there is a noticeable third color at the junction of the two colors. The higher the realism level of the actual image, the better. Check if there are any issues such as wire drawing, misting, blocking, or missed printing.

3、外观的整齐度：

3. Appearance neatness:

要先观察袋子的挺度。一般平整度越高越好，但是因取材的不同需要除外。比如尼龙和高压膜复合制成的袋子，袋子的热封处就会有波浪形；还需要观察袋子的切边是否整齐，越整齐越好。

First, observe the stiffness of the bag. Generally, the higher the flatness, the better, except for the need for different materials. For example, bags made of nylon and high-pressure film composite will have a wavy shape at the heat seal of the bag; It is also necessary to observe whether the cut edges of the bag are neat, the neater the better.

4.袋子的结实程度。袋子的结实度首要分为两种契合结实度和热风结实度。袋子因选材不一样所以结实程度也不一样。首要的区分办法即是对准袋子的封边处用手撕，假如很难撕就阐明热封结实度好。不然即是欠好。

4. The firmness of the bag. The firmness of bags is mainly divided into two types: fit firmness and hot air firmness. The strength of the bag varies due to different materials used. The primary distinguishing method is to align the edge of the bag and tear it by hand. If it is difficult to tear, it indicates that the heat seal is strong. Otherwise, it would be bad.
