With the increasing popularity of thermal paper in supermarket shopping, the preservation time of thermal paper has become another big puzzle for people; Relevant authoritative information is scarce. Here, I will give you a simple popularization of the preservation time of thermal paper.

The protective coating on the thermal paper plays a key role in the storage time after printing; under natural conditions, the coating The layer can absorb a part of the light that causes the chemical reaction of the thermal coating to slow down the deterioration time of the printing paper. If the protective coating on the surface of the thermal paper is not uniform, it will reduce the protection of the thermal coating, thereby reducing the storage time of the thermal paper.

This does not mean that thermal paper cannot have a long storage time; in fact, good thermal paper printing After that, it can be stored for several years, but if the formula of the thermal paper coating is unreasonable or the storage method is incorrect, it can only be stored for a few months.

If you desperately need to know how long the thermal paper you are holding can last, then here, the editor teaches Your simple and effective way to identify the storage time of thermal paper-natural light irradiation identification, this method is very simple to operate, just apply the same type of highlighter to the different printed paper and place it under the sun. After exposure to the sun, they will eventually turn black. The longer it takes to turn black, the longer the storage time of this thermal paper will be.

Shandong Litai Paper is advancedThe thermal paper manufacturer is committed to producing advanced thermal paper for thermal printers. The coating formula is reasonable and the raw materials used are good, so that the thermal paper can be preserved. The time is greatly extended.
