How to identify the crepe paper tape true or false

1. The adhesive will be pinched and then quickly pulled open, you can pull out of 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 point pull, the glue is a lot of impurities, the glue has no cohesion.

2. Too much water has evaporated, this kind of tape at this time the initial adhesive force has declined very much, feel can be resolved. The color of the whole roll of good adhesive tape and the color after pulling out of a little difference, because the good adhesive tape has strong masking, there is no color overlay.

3. Look at the surface of the crepe paper tape, the tape just after the divided into finished products when there are bubbles, placed a week after the bubbles will basically dissipate, pure tincture fat glue tape surface smooth, without any white points, mixed with impurities of the tape has a lot of irregular distribution of white points, with the hand pressure is not dispersed, is not the same as the bubble.

4. When choosing crepe paper tape must see clearly the width and the thickness of the adhesive tape masking tape, formal production of adhesive tape paper tube with high density of paper tube, plane without the paper scraps, and the thickness of the tube, 100 meters below the tape is 3 mm, more than 100 meters is 4 -- 5 mm, And small business USES thick paper tube for blind consumption, it plies to achieve 5-7 millimeter ply normally, go up in the outward appearance thereby bigger, but glue thick very apparent comparison comes out.

5. Do not feel the viscosity by hand alone, because the doped tape is not volatile when the initial adhesive force is very high, to use tape paste objects and then quickly open to see the holding force, repeatedly paste several times with the hand touch, the obvious feeling of falling.
