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.Jer ljepilo nije jednoliko.
