1. Measure the pulling force of the sealing tape: pull out a part of the tape and pull it open by hand to see if it can withstand strong pulling. 2. Smell the smell: see if the sealing tape has a considerable sour odor, if there is, it is an inferior tape coated with inferior glue. 1.

3. Look at the color: with the naked eye to see whether it is yellow, this kind of BOPP material is poor, ordinary light yellow and white are better, indicating that the content of impurities is low, the purity is high, and the corresponding toughness is large.

4. Measure the adhesiveness of the sealing tape: It can be tested manually. Pull a roll of tape and stick it on the carton and tear it off to see if the carton is torn off together. Be careful not to test the viscosity of the tape with the palm of your hand, be sure to test it on the carton.

5. Measure the length and width of the whole roll of sealing tape: Because the length of the tape is difficult to measure, many tape lengths in the market are falsely reported. Even the tape with the same thickness will also be affected by the thickness, size and winding tightness of the paper tube. Due to factors such as different lengths of use, the durability of the tape can only be felt after the actual operation.

6. Measure the thickness of the sealing tape: Generally, the thickness of the tape on the market ranges from 40u-60u (the thickness of the glue to teach the BOPP film), of course, the price is also very different. The 60u tape is very thick, but with the same thickness, the length is shorter, and the 40u tape is long but very thin and easy to break. The tape produced by Shenyang Huanyu Tape Factory is a 52u film, which can reach the best length and toughness.
