It is their common desire for buyers to buy goods with good price and low price. Let us tell you how to know the good and poor quality of duct tape.
 
In 1, touch the adhesive side of the tape, and then hand plane posts with duct tape to move, if the hand has come to feel that their glue tape sticky resistance and viscous resistance is quite large, it shows that the tape initial adhesion is very good. Under normal circumstances, if the tape if viscosity is not good, is not stick. So this is not a tape we want to buy things.
 
The 2 side view without glue, the surface is clear lines orderly arrangement and the arrangement of relatively dense, and relatively thick cloth tape thickness. If it is a cloth tape like this, the tensile strength of the duct tape is relatively large, more able to withstand major items of tension. If the grain is scarce, so this kind of tape under heavy items tension is not so big.
 
3, a hand to tear tape, cloth tape if compare an easy job to do be torn off, so the substrate tape is good, because the tape itself is good, the maneuverability is strong, on the contrary, if the base tape is not good, not easy to tear off, then on the duct tape not how good the operation.
