Today, the sealing tape manufacturer will teach you to distinguish the advantages and disadvantages of the sealing adhesive and choose the suitable sealing adhesive supplier.

1. First look at the thickness of the sealing tape tube, the thickness of the ordinary paper core is 2-3mm. Look at the inner diameter of the paper core, the common inner diameter is 7.6cm

2. Smell the smell of the sealing glue. If the smell is strong or there is a peculiar smell, it means that the product quality is not good.

3. Check the appearance of the sealing glue, including whether the two sides of the sealing glue are sticky and whether there is a gap. Good quality sealing glue is not sticky on both sides, and there is no gap

4. Check whether there are air bubbles on the surface of the sealing adhesive. Good quality sealing film is very tight and there will be no air bubbles. Of course, if it is a new factory sealing adhesive, there may be a little air bubbles.

5. Check the pulling force of the sealing glue. If the sealing glue is particularly easy to break, it means that it is of inferior quality. Good sealing glue is more difficult to use a better transparent film.

6. It is very important to check the viscosity of the sealing glue. There are also many inspection methods. You can seal the box with sealing glue, and then remove it suddenly. The more the surface of the box can be peeled off, the better the adhesion. You can also pull a longer section of sealing glue according to the requirements, divide it in half, fold it in the middle to fit it, and then pull it up suddenly. Parts of the sealing glue fracture indicates strong viscosity.
