How to distinguish the color tape! The market of color box sealing tape of every hue types, specifications, beyond count, length and variety. How do we identify better than bad, there is a tape to introduce you: how to distinguish between good and bad? For colored tape is to facilitate the use of marking and masking purposes, the general beige and yellow more. A lot of people think that the color of the film is the color of the film, in fact, the color is the color of glue. The adhesive will be tightly closed and then quickly opened, you can pull out the side of the glue, you can see the purity and transparency of the original film. The most important thing is to see the thickness of the glue. If there is no glue is pulled open or point to open, this glue is a large number of impurities, glue, no cohesion. Two is too much water, has been volatile, at this time the adhesive force of the adhesive tape has dropped very powerful, feel able to distinguish.
The yellow tape coated on the object, the better the better the better the quality of the glue, the better the quality. Adhesive tape in the appearance of the comparison, the glue is less, the entire volume of the tape doped with impurities is very deep, open the tape after the high transmittance. Good tape the whole volume of the color and the color after the opening of a small difference, because a good sealing tape has a very strong masking, there is no color overlay. The inferior tape doped to impurities onto BOPP coated film, only the use of backward direct glue, so there is often a large impurity particles is not completely dissolved the stick knife, so the tape in use often have the line (a place without glue).
