BOPP packaging tapes are an indispensable product in our daily life and factory packaging. Due to its not high technical content and many different packaging tape manufacturers, BOPP packaging tapes on the market are uneven. What should we pay attention to when buying? Today, we tell you something:
1. BOPP packaging tapes tightness
Packaging tapes are rolled loosely, they always create the illusion of being thicker and more cost-effective. In this case, it is not scientific. BOPP packaging tapes are roll tightly, can reduce the possibility of glue overflow and looks more beautiful.
2. BOPP packaging tapes smelling
If packaging tapes' smell is pungent, there is a sour smell, the holding power of this kind of tape is very poor, especially in the low temperature environment, it will crack when it basically sticks to the carton
3. Checking BOPP film brightness
Generally bad tapes are dark in color, and the probability of breaking of this kind of packaging tapes is very high and the strength is poor.
4. Checking BOPP packaging tapes color
Under normal circumstances, the whiter the appearance of the transparent packaging tapes, the purer the texture, the less impurities, and the better the adhesiveness.
5. Checking BOPP packaging tapes size
That is the main problem. Some bad packaging tape suppliers label the sizes on cartons are not same as packaging tapes actual sizes. We can use a ruler to check packaging tape width, but thickness and length need be checked by professional machine. Some bad packaging tape suppliers provide lower prices, because they produce less length or less thickness tapes, that is scamp work and stint material.
