First, smell it. The PVC electrical tape factory reminds you: The qualified tape produced by the regular manufacturer has no peculiar smell. If you find a sour smell when you buy tape, you must not buy it. Because the holding power of this kind of tape is very poor, especially in the low temperature environment, the tape is very easy to crack and will soon lose its adhesiveness. This kind of tape must be a poor quality product.
Second, look at the brightness of the film and touch the thickness of the film. Generally speaking, the color of inferior tape products will be much darker than qualified tape, and if you touch it by hand, generally inferior tape will be harder, and because the film is thicker, the actual number of meters will definitely be reduced. The film of a good tape is relatively soft and has good tensile properties. Therefore, the brightness and thickness of the tape film are two very important indicators, which must be observed carefully.
Third, look at the color of the tape. Under normal circumstances, the whiter the color of the transparent tape and the fewer impurities in the tape, can the normal adhesiveness be guaranteed. The tape products below 100 meters have a certain degree of transparency and the paper tube can be seen. Inferior tapes are generally yellowish, and there are irregular white spots on the surface. When pressed by hand, there will be imprints of impurities or dry glue that cannot be removed. There is no doubt that the production process of inferior tape is definitely very rough, so the color of the tape will definitely be yellowish and there will be impurities on the surface.
These are the three aspects that the PVC electrical tape factory reminds you to pay attention to when choosing tape products
