How to identify the storage time of thermal paper?

With the increasing popularity of thermal paper in supermarket shopping, the storage time of thermal paper has become another big puzzle for people; relevant authoritative information is scarce, and I will give you a guide on the storage time of thermal paper. A simple popularization.

The protective coating on the thermal paper plays a key role in the storage time after printing; under natural conditions, the coating can absorb part of the light that causes the thermal coating to produce a chemical reaction, thereby slowing 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 be stored for a long time; in fact, good thermal paper can be stored for several years after printing, but if the formulation of the thermal paper coating is unreasonable or the storage method is incorrect, It can only be stored for a few months.

If you urgently need to know how long the thermal paper you are holding can be stored for, then here, the editor will teach you a simple and effective way to identify the length of thermal paper storage—— Natural light irradiation identification, this method is very simple to operate, just smear the different printed paper with the same type of highlighter and expose it to the sun naturally. Eventually they will all turn black. The longer it takes to turn black, this The longer the storage time of thermal paper will be.
