The tapes we see in daily packaging and sealing are usually called sealing tapes, transparent tapes, transparent tapes, etc. Many customers will have these questions when buying sealing tapes.
The reason why many sealing tapes bought in the market or supermarket have fewer bubbles is that the bubbles will slowly disappear automatically because the length is less than 100 yards because it is placed for a long time, and the paper tube inside can be seen from the transparent part outside. The larger the tape, the longer it will be placed before it becomes completely transparent and no bubbles can be seen.
Of course, there is also a kind of tape produced by imported machines, which will exhaust the air from the production and then rewind it. The produced tape is also completely transparent, but the cost will increase a lot. However, the domestic tapes generally used for packaging and sealing do not need to be so required, because the bubbles in the tape will not affect the quality of the tape, such as tension and viscosity, which have nothing to do with bubbles, so each manufacturer does not need to worry about this problem and can use it with confidence. The sealing tapes just produced by the manufacturer all have bubbles, and the bubbles will disappear automatically after being placed for a period of time. The longer the placement time, the higher the transparency of the tape will be.
