緣由一：產生靜電使不干膠紙起泡
Cause: Generating static electricity to foam adhesive paper
在我國北方地域，冬季經常很枯燥，貼標機在自動貼標過程中常常就會產生靜電，而靜電很容易讓不干膠紙發作起泡。另外，在貼標過程中，不干膠紙之間以及不干膠紙和貼標機相關部件相互接觸摩擦也會產生靜電，從而形成不干膠紙起泡。
In the northern part of China, winter is often very dull. In the process of automatic labeling, the labeling machine often produces static electricity, which easily makes the sticker foam. In addition, in the labeling process, the contact and friction between the adhesive paper and the relevant parts of the labeling machine will also generate static electricity, thus forming the foaming of the adhesive paper.
處理辦法：
Approaches:
1、堅持操作車間的溫濕度，溫度普通控制在20－22℃，濕度堅持在50% ；
1. Adhere to the temperature and humidity of the operation workshop. The temperature is generally controlled at 20-22 C and the humidity is 50%.
2、運用銅金屬線停止放電
2. Stop Discharge with Copper Wire
緣由二：貼標體自身產生的緣由
Cause 2: The Cause of Label-fitted Body
產生起泡的緣由也可能是貼標體自身產生的問題，有幾種可能：
The cause of foaming may also be the problem of label-fitted body itself. There are several possibilities:
1、貼標體外形不平，比方是扁平的或規則曲面的等；
1. The shape of the label body is uneven, such as flat or regular surface.
2、貼標體上有膠水，雜質等，發作化學反響使得不干膠紙起泡；
2. There are glue and impurities on the label sticker. The chemical reaction makes the sticker foam.
3、沒依照貼標體材質選用資料
3. Failure to select materials according to label material
處理辦法
Treatment method
1、貼標過程中，需求用傳送帶將貼標體固定好
1. In the labeling process, the labeling body needs to be fixed with a conveyor belt.
2、貼標體需求干凈枯燥后再停止貼標
2. The labeling body needs to be clean and dull before stopping labeling.
3、依照貼標體的材質來選擇不干膠資料，如透明玻璃或塑料瓶體，軟質的瓶體要選擇PE、PVC的薄膜資料，硬質的就應該選擇PET、BOPP；底紙應選擇潤滑度好的，如PET材質的底紙。
3. Choose the non-drying adhesive materials according to the label material, such as transparent glass or plastic bottles, soft bottles should choose PE, PVC film materials, hard should choose PET, BOPP; base paper should choose good lubrication, such as PET material base paper.
緣由三：貼標機的壓輪壓力不夠
Reason 3: Pressure of press wheel of labeling machine is not enough
貼標機在停止自動貼標的過程中，后一個步驟是壓輪將不干膠紙平整貼到商品上，假如它的壓力不夠將會招致標簽紙無法完好貼合上去，產生起泡現象。
In the process of stopping automatic labeling of labeling machine, the last step is to press the roller to paste the dry adhesive paper flat on the merchandise. If the pressure is not enough, the label paper will not fit perfectly, resulting in blistering phenomenon.
處理方法：聯絡貼標機供給商對機器停止調整。
Processing method: Contact labeling machine supplier to stop adjusting the machine.
緣由四：不干膠紙涂布的膠水不平均
Reasons 4: Uneven glue in the coating of self-adhesive paper
標簽印刷廠在消費不干膠紙的過程中，假如膠水涂布的不平均也會形成起泡。
In the process of consuming self-adhesive paper in label printing plant, if the unevenness of glue coating can also form bubbles.
防止辦法：選購不干膠紙時，選擇有實力的不干膠印刷廠，例如遠競達，選擇質量好的標簽紙
Preventive measures: When choosing non-adhesive paper, choose powerful non-adhesive printing plants, such as Yuanjinda, and choose good quality label paper.
I believe that after reading the introduction of Jinan Label Printing http://www.seven2000.com, I will have my own understanding of this aspect, and other problems can be solved well in the future.
