With the increasing popularity of thermal paper
in supermarket shopping, the storage time of thermal paper has become another big puzzle. the relevant authoritative information is very few, here we make a brief introduction of the storage time of thermal paper.
The protective coating on thermal paper plays a key role in the preservation time after printing. Under natural conditions, the coating can absorb a part of the light that causes the chemical reaction of thermal coating, thus slowing down the deterioration time of printing paper. If the protective coating of thermal paper is not uniform, it will reduce the protection of the thermal paper, thus reducing the storage time of thermal paper.
This does not mean that thermal papers cannot be stored for a long time. In fact, good thermal papers can be stored for several years after printing, but if the formulation of thermal papers is unreasonable or the preservation method is incorrect, they can only be stored for several months.
If you urgently need to know how long your thermal paper will last, here is a simple and effective way to identify the duration of thermal paper storage - natural light identification. This method is very simple to operate, just print different papers with the same fluorescent pen and then put them in the sun for natural exposure. Eventually, they all turn black. The longer the blackening takes, the longer the thermal paper will last.
Our company is a high-level thermal paper manufacturer, dedicated to the production of high-level thermal paper for thermal printers. The coating formulation is reasonable and the raw material is good, which greatly prolongs the storage time of thermal paper.
