What is the reason why the sealing tape doesn't stick? There are more and more cases of adhesive tape in our daily life, but we can't see the phenomenon that we can't stick adhesive tape in the back of some cases after a period of time in our daily life? Some tapes are sticky when touched by hand. As a result, the sealing effect is not good. They always open by themselves. Any selected tape is the same. Why on earth? Now let's explain it to you by Xiaobian.

其實是膠水的問題，手摸著挺粘，這是初粘力好，粘上后自己跳開，是持粘力不好。初粘力和持粘力是成反比的，就是說用手摸著很粘的封箱膠帶，持粘力就會差。

In fact, it's the problem of glue. It's very sticky when touched by hand. This is the good initial adhesion. When you stick it, you jump away. It's the poor adhesion. The initial adhesive force is inversely proportional to the adhesive holding force, that is, if you touch the very sticky sealing tape with your hand, the adhesive holding force will be poor.

膠水一般固含量高的粘性會好，市面上常用的一般固含量在50左右，要粘性好的話，zui好用52的固含的。但jia格可能會相差很多。涂膠的厚度也有關(guān)系，一般涂膠厚度在20-22左右，涂越薄粘性越差，但不是涂越厚粘性就會越好。烘干溫度看實際操作，和機器運轉(zhuǎn)速度也有關(guān)系。

Glue with high solid content generally has good viscosity. The commonly used solid content in the market is about 50. If it wants good viscosity, Zui it is easy to use the solid content of 52. But the Jia grid may differ a lot. The thickness of gluing is also related. Generally, the gluing thickness is about 20-22. The thinner the coating, the worse the viscosity, but not the thicker the coating, the better the viscosity. The drying temperature depends on the actual operation and is also related to the running speed of the machine.

一般封箱帶都是OPP膜涂水膠。其初粘力和持粘力都不好。其大的特 征就是jia格便宜。建議使用時不要拉太緊，因為膜會被拉伸，這樣膠不夠粘的 時候就會往回彈。另外可以封箱后用剪刀刀背或美工刀刀背刮壓下封口處。使得膠帶與紙 粘合的更牢固這樣就不容易崩開了。

Generally, the sealing tape is OPP film coated with water glue. Its initial adhesion and adhesion holding force are not good. Its big feature is that Jia grid is cheap. It is recommended not to pull too tightly when using, because the film will be stretched, so that the glue will rebound when it is not sticky enough. In addition, the sealing part can be scraped and pressed with the back of scissors or art knife after sealing the box. Make the adhesive tape and paper bond more firmly, so it is not easy to break.

冬天因為氣溫較低膠水粘性會差一些，可以換成油性膠水，把膠水層加厚，或者把膠帶放在暖房里。

In winter, because the temperature is low, the glue viscosity will be poor. You can replace it with oily glue, thicken the glue layer, or put the tape in the greenhouse.
