NCR paper roll is widely used in supermarkets, shopping malls, restaurants, hotels, and hospitals. The quality of the paper roll is also related to the quality of printing and the time of preservation. Let's take a look at the identification method of the quality of NCR paper roll.

First of all, the appearance of the paper, good quality of the paper is of heat-sensitive cashier paper with uniform color, smooth, high whiteness, advantages of pan-green. If the paper is white, then the protective layer and thermal sensitive layer of the paper are not reasonable. Too much silver powder is added. Secondly, use fire to bake and heat the back of the paper. If the color on the paper is brown, it indicates that the heat-sensitive formula is not reasonable and the storage time may be relatively short.
