1. The smell, if the smell is very strong, has a sour taste, this tape retention is very poor, especially in low temperature environment, basic stick on the carton will craze, taste when it grows in the early feel viscous force is very sticky, but will soon dry rubber surface, loss of gum, that time in the tape surface has crack.Minħabba li l-kolla mhix uniformi.
2. Look at the brightness of the film. Generally, poor quality tapes are dark in color.
3. Ħxuna tal-idejn - film tal-felt. Tapes b'film iebes huma ġeneralment inferjuri, u n-numru attwali ta 'meters jitnaqqas minħabba l-ħxuna tal-film.Il-film li jagħżel it-tejp li jwaħħal tajjeb huwa aktar artab, il-medda tas-sess bl-idejn twila hija tajba.
4. Look at the color. Generally, the whiter the appearance of the transparent tape, the less impurities in the tape, so as to ensure the normal adhesiveness.Tape isfar biex tara jekk hemmx distribuzzjoni irregolari ta 'tikek bojod fuq il-wiċċ tat-tejp, bi pressjoni tal-idejn biex ma timsaħx għal impuritajiet jew stampi niexfa li jwaħħlu, dan il-prodott ġeneralment għandu riħa.
5. Look at the paper tube: the choice of thick paper tube tape is generally in order to mislead consumption.Tape production began from abroad, so the tape paper tube 7.6 cm inner diameter are unified, but inferior adhesive tape on the thickness of the tube is to do, and cause this kind of situation and many consumers still have a relationship, many people think that the thicker the paper tube, the outer ring, the greater the tape is, the more fiercely a listen to is correct, it can calculate carefully?Say with 3 millimeter paper tube and 7 millimeter paper tube ratio, if two rolls of tape from the outer diameter of the paper tube to the edge of the tape pure tape thickness is 1 centimeter, we can use the mathematical formula to calculate 7 millimeter paper tube and 3 millimeter paper tube each centimeter glue thickness can more meters of tape?
6. Ara l-fermezza, tejp li jwaħħal fil-proċess ta 'minn nofs - il-prodott lest għall-prodott lest qed juża l-magna tal-istralċ sezzjonali, għandu ċerta tensjoni, tensjoni, tejp se jieħu aktar issikkat, tejp skond ir-rutina għandu tkun pulita, tejp bħal dan m'għandu l-ebda vojt, il-grad tal-kolla magħqud ma 'l-arja huwa żgħir, jista' jtawwal il-ħajja fuq l-ixkaffa tat-tejp li jwaħħal u jirriżerva limitati kbar għat-tejp li jwaħħal.Additional to inferior tape, because contain impurity among them, transparent tape which is cheap, so spread glue is not even, transparent tape, won & #39;t have a problem at that time after take a finished product in roll, but the time is slightly long begin to appear aperture.Barra minn hekk, it-tejp li jwaħħal huwa rrumblat fuq wiċċ ċatt fil-proċess tal-użu, li huwa konvenjenti ħafna biex issib fetħiet.
