With the continuous development of the current era, the use of polypropylene anticorrosive adhesive tapes is also increasing, but many users will find that the types of tapes on the market have changed when they make purchases, and they are no longer single. The products are colorful. Although they are very good-looking, they often give people a feeling of poor quality. Therefore, when purchasing, we always worry about the poor quality of colored products. Then we are in How to judge the quality of the product when making a purchase?

   1. Polypropylene anti-corrosion adhesive tape has less glue in appearance, and the color of the whole roll of doped polypropylene anti-corrosion tape is very dark, and the light transmittance is high after being stretched.

  2. Many people with colors think that it is the color of the film, but the color is actually the color of the glue.

  3. To apply impurities to the BOPP film for doped inferior products, only the relatively backward direct gluing method is used, so there are often large impurity particles that are not completely dissolved and jamming occurs. There are often lines in use.

  4. The colored polypropylene anticorrosive adhesive tape is used for marking and masking purposes. Generally, beige and khaki are more common.

   5. Pinch the pair of adhesives tightly and then quickly pull them apart, you can pull off the glue on one side, and you can see the purity and transparency of the original film.

  6. Too much water has evaporated. At this time, the initial adhesion of this adhesive tape has dropped so much that the hand feel can be distinguished.

  7. The color of the entire roll of high-quality polypropylene anticorrosive adhesive tape is not much different from the color after unfolding, because it has strong opacity and there is no color superimposition.

   8. The important thing is to see the thickness of the glue. If there is no glue that is pulled apart or pulled apart in dots, there are a lot of impurities in this glue, and the glue has no cohesion.

   When we are making a purchase, if we cannot judge the quality of the colored polypropylene anticorrosive adhesive tape, we can use the above methods to judge and test, which will not only ensure the quality of the purchased tape, but also allow us to proceed. There are not so many doubts when buying, of course, when making a purchase, you must go to a regular manufacturer to make the purchase, so that the quality of the product is more guaranteed.
