印刷封箱胶带不沾的原因是什么?
发布于:2022/03/10 封箱胶带不沾的原因是什么?在我们的日常生活中处处都能见到或用到封箱胶带,有些企业在购买封箱胶带过程中买的数量比较多,但是经过一段时间的放置,越后面用的胶带就会出现越来越不粘的现象,封箱胶带为什么不粘?有的胶带用手摸着挺粘,结果封箱效果不好,总是自己就开了,任何选择好的胶带都一样,这到底是为什么呢?下面就由小编就给大家解释一下吧。
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.
其实是胶水的问题,手摸着挺粘,这是初粘力好,粘上后自己跳开,是持粘力不好。初粘力和持粘力是成反比的,就是说用手摸着很粘的封箱胶带,持粘力就会差。
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.
胶水一般固含量高的粘性会好,市面上常用的一般固含量在50左右,要粘性好的话,zui好用52的固含的。但jia格可能会相差很多。涂胶的厚度也有关系,一般涂胶厚度在20-22左右,涂越薄粘性越差,但不是涂越厚粘性就会越好。烘干温度看实际操作,和机器运转速度也有关系。
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.
一般封箱带都是OPP膜涂水胶。其初粘力和持粘力都不好。其大的特 征就是jia格便宜。建议使用时不要拉太紧,因为膜会被拉伸,这样胶不够粘的 时候就会往回弹。另外可以封箱后用剪刀刀背或美工刀刀背刮压下封口处。使得胶带与纸 粘合的更牢固这样就不容易崩开了。
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.
冬天因为气温较低胶水粘性会差一些,可以换成油性胶水,把胶水层加厚,或者把胶带放在暖房里。
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.
