Tape is one of the commonly used packaging materials in our daily life. When tape manufacturers produce tape, they have high quality requirements. However, some black-hearted small businesses also use shoddy products to gain certain benefits, which has a negative impact on consumers and tape manufacturers. So, what are the criteria for judging the quality of tape?
1. Whether the tape surface is smooth and without wrinkles. Under normal circumstances, bubbles can be seen in the newly produced tape, which is caused by the production environment. After being placed for a week, the bubbles will basically disappear. The surface of the high-quality packing tape glue is smooth, without any white spots, and its surface is also extremely smooth, without any wrinkles. On the contrary, the tape mixed with impurities has many irregularly distributed white spots, which will not disappear when pressed by hand.
2. Whether the adhesive tape is good. In terms of viscosity, we must pay attention not to feel the viscosity of the tape only by hand, because the adhesive tape with impurities is very high when it is not volatilized. Therefore, when distinguishing the adhesiveness of the adhesive tape, we need to use the adhesive tape to stick the article and quickly pull it apart to see the holding force. Repeat the pasting several times and then touch it by hand until the adhesiveness drops significantly. Through comparison, it can be found that good adhesive tape will be more wear-resistant and sticky longer than poor quality tape.
3. Whether the toughness of the tape is good. Toughness refers to the ability of the tape substrate to absorb energy during plastic deformation and fracture. The better the toughness, the lower the possibility of brittle fracture. The high-quality tape has good toughness and can well protect the packaged products.
