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.Paske lakòl la pa inifòm.
2. Look at the brightness of the film. Generally, poor quality tapes are dark in color.
3. Epesè nan men fim - te santi. Kasèt ak fim rèd yo jeneralman enferyè, epi yo pral kantite aktyèl la nan mèt ap redwi akòz epesè nan fim.Fim nan bon tep adezif chwazi se douser, detire ak men nan fè sèks long se yon bon bagay.
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.Tep jòn yo wè si gen yon distribisyon iregilye nan tach blan sou sifas la nan kasèt la, ak men presyon pa siye lwen pou enpurte oswa adezif simagri sèk, pwodwi sa a jeneralman gen yon sant.
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. Gade fermeté a, tep adezif nan pwosesis la nan soti nan pwodwi semi - fini nan pwodwi a se lè l sèvi avèk machin nan seksyonè likidasyon, gen tansyon an sèten, tansyon, tep ap pran plis sere, tep selon woutin ta dwe ... dwe pwòp, tankou tep pa gen okenn espas, degre nan lakòl konbine avèk lè a piti, ka prolonje lavi sa a ki etajè nan tep adezif ak gwo rezèv limite tep la adezif.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.Anplis de sa, se tep la adezif woule moute sou yon sifas ki plat nan pwosesis la nan itilize, ki se trè pratik jwenn ouvèti.
