屏蔽袋鋁箔袋的品質怎么區分比較好？

防靜電屏蔽袋通常用于電子組件的包裝，以防止電子組件容易發生的靜電發電所造成的損害。通常，防靜電屏蔽袋采用二層復合或更高的四層結構。袋里形成法拉第籠感應罩效應，[敏感詞]保護袋內物品與靜電場隔離，防止靜電積累，免受靜電危害。

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.

防靜電屏蔽袋采用二層或四層復合：（VMPET/CPE或PET/AL/NY/CPE），具有優良的防靜電、防射頻、防水蒸汽滲透、防鹽霧等諸多功能，還有屏蔽外部人員、設備的ESD靜電放電及外部電磁輻射性能。適用于PCB、IC等靜電敏感類高科技電子產品的運輸與包裝。

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.

屏蔽袋具有優良的防靜電、防射頻、防水蒸汽滲透、防鹽霧等諸多功能。它們獨特的四層結構可形成“感應罩”效應以保護袋內物品與靜電場隔離．另外里面一層是由可靜電乙烯組成，防靜電功能優越。防靜電屏蔽袋材料內外層由透明的防靜電材料構成，中間為半透明的導電金屬層，因而具有良好的防靜電、靜電屏蔽性能。

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:

鋁箔袋需要無異味。有異味的袋子一般讓人覺得不符合衛生標準，還可能會影響袋子的正常使用。如果沒有異味，需要檢查袋子的透明度，清晰度是否均勻、否有雜質感等等。

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、印刷質量：

2. Printing quality:

看兩種顏色的拼接處是否有明顯的第三色，實物圖的逼真水平越高越好，看看是否有拉絲、霧版、堵版、漏印等現象。

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、外觀的整齊度：

3. Appearance neatness:

要先觀察袋子的挺度。一般平整度越高越好，但是因取材的不同需要除外。比如尼龍和高壓膜復合制成的袋子，袋子的熱封處就會有波浪形；還需要觀察袋子的切邊是否整齊，越整齊越好。

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.袋子的結實程度。袋子的結實度首要分為兩種契合結實度和熱風結實度。袋子因選材不一樣所以結實程度也不一樣。首要的區分辦法即是對準袋子的封邊處用手撕，假如很難撕就闡明熱封結實度好。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.
