Adhesive tape manufacturer tells you how to distinguish the adhesive strength of adhesive tape; the quality of Bopp adhesive tape is very important for the quality of adhesive tape. We can learn the method to distinguish the quality from the adhesive tape manufacturer. Generally speaking, there are two standards for the quality of adhesive tape in use, one is the initial adhesive force, the other is the retention force. The two are in inverse proportion. The adhesive tape with the initial adhesive force lower than No. 10 has less glue coating, generally only about 20 microns, such as stationery tape, and the tape for general promotion and binding. The initial adhesion of normal sealing tape is between 15 and 20, and the thickness of this tape glue is generally 22 to 28 microns, which is in line with the standard thickness. For colored tape is to facilitate marking and masking purposes, generally beige and Tan are more. Many people think that the color of the colored tape is the color of the film. In fact, the color of the tape is the color of the glue. At present, most of the tape on the market is mixed with impurities, so the thickness is increased. In order to shield the impurities, the glue is also mixed with color powder, which is more serious to distinguish.
