The Importance of Protective Coating of Thermal Paper

If the protective coating of thermal paper is uneven, printed pictures will be with bad quality, somewhere is with strong color while somewhere is with light color, if the chemical recipe of thermal coating is unreasonable, it will cause short retention time, good printer paper can be stored for 5 years( in the condition of normal temperature without direct sunlight), nowadays, some thermal paper can be stored for 10 years,if the chemical recipe of thermal coating is unreasonable, it just can be stored for several months.

Protective coating is important for retention time, it can absorb part of light that can make thermal coating produce chemical reaction for retarding thermal paper goes bad, it also can protect the thermal element of printer from damaging. However, if the chemical recipe of thermal coating is unreasonable, the protection for thermal coating will be reduced, even in the process of printing, there will be some small grains fall off to rub thermal elements of printer and damage the thermal elements.
