How to identify the beauty paper pressure sensitive tape true or false

In daily life, how do we distinguish the beauty of paper pressure sensitive tape is true or false?

First, the pair of adhesive pinch and then quickly pull apart, you can pull out one side of the glue, you can see the purity and transparency of the original film. The most important thing is to see the thickness of the glue. If no glue is pulled or punctured, there is a lot of impurities in the glue and the glue has no cohesion.

Two, too much water, has volatilized, at this time the initial adhesive force of this tape has declined very badly, feel can distinguish. The color of the whole roll of good tape is not much different from the color of the last one, because the good tape has a strong shelter, there is no color superposition.

Three, look at the tape surface, tape just after the strip into the finished product when there are bubbles, placed a week after the bubble will basically disperse, pure tincture of grease glue tape surface smooth, without any white spots, mixed with impurities of the tape has a lot of irregular distribution of white spots, hand pressure does not disperse, is not the same as the bubble.

Four, the choice of tape must see clearly the width of the tape and the thickness of the tape, the formal enterprise production of tape paper tube are using a higher density of paper tube, cut without paper, and the thickness of the paper tube below 100 meters of tape is 3 mm, 100 meters above is 4-5 mm, and small enterprises to deceive consumption using thick paper tube, Usually the thickness is up to 5-7 mm thickness, so as to be relatively large in appearance, but the thickness of the glue is obviously compared out.

Five, do not feel the viscosity by hand alone, because the doped tape is very high when there is no volatilization, to paste the object with tape and then quickly open to see the retention force, repeated paste several times and then touch with the hand, it will obviously feel the decline in flexure.
