Material characteristics:Not waterproof, not oil resistant, and can tear.
Scope of application:Shopping mall electronic scale price tags, cash register printing paper, and chemical laboratory paper.
Carbon ribbon is not required. Thermal label paper is a paper material treated with a highly thermosensitive coating. The highly sensitive surface material can be used for low-voltage print heads, thus minimizing wear on the print heads. Thermal paper is a type of thermal paper specifically used for electronic scales and cash registers. The simplest way to test thermal paper is to scratch it with your fingernail, leaving a black scratch on the paper. Thermal paper is suitable for shelf labels in cold storage, freezers, etc., and its size is mostly fixed at 40mmX60mm standard.

Selection and quality identification of thermal label paper:
1) Thermal paper is specifically used for printing on thermal printers and thermal fax machines. Its quality directly affects the printing quality and storage time, and even affects the service life of printers and fax machines.
2) At present, the quality of thermal label paper on the market varies greatly, and the country has not yet issued a national standard. Many users are also unclear about how to identify the quality of thermal paper. This provides convenience for many businesses to produce inferior thermal paper, causing losses to users. The lighter issue is that the storage time of thermal printing paper becomes shorter, the handwriting becomes blurry, and the heavier issue is damaging the printer. Here's how to identify the quality of thermal paper to avoid falling for it again.
3) Thermal printing paper is generally divided into three layers: the bottom layer is the paper base, the second layer is the thermal coating, and the third layer is the protective layer. The thermal coating or protective layer mainly affects the quality of thermal printing paper. If the coating of thermal printing paper is uneven, it will cause some areas to have dark colors and some areas to have light colors during printing, and the printing quality will be significantly reduced. If the chemical formula of the thermal coating is not reasonable, it will cause the storage time of thermal printing paper to become very short. Good printing paper can be stored for 5 years (under normal temperature and avoid direct sunlight) after printing. Nowadays, there are also long-lasting thermal paper that can be stored for 10 years. However, if the formula of the thermal coating is not reasonable, thermal printing paper may only be stored for a few months.
4) The protective coating is also crucial for the storage time after printing. It can absorb some of the light that causes chemical reactions in the thermal coating, slow down the deterioration of the printing paper, and protect the thermal components of the printer from damage. However, if the protective coating is uneven, it will not only greatly reduce the protection of the thermal coating, but even cause small particles of the protective coating to fall off during the printing process, rubbing against the thermal components of the printer, resulting in damage to the printed thermal components.
There are several methods to distinguish the quality of thermal label paper:
1. Appearance: If the paper is very white, it indicates that the protective coating and thermal sensitive coating of the paper are unreasonable, and too much fluorescent powder has been added. A better paper should have a slight greenish tint. If the smoothness of the paper is not high or appears uneven, it indicates that the coating on the paper is not uniform. If the paper appears to reflect strong light, it is also due to the addition of too much fluorescent powder, resulting in poor quality.
2. Fire baking: The method of fire baking is also very simple. Use a lighter to heat the back of the paper. If the color appearing on the paper after heating is brown, it indicates that the heat sensitive formula is not very reasonable and the storage time may be relatively short. If there are small stripes or uneven color blocks on the black part of the paper, it indicates that the coating is uneven. High quality paper should be black green (with a hint of green) after heating, and the color blocks should be uniform, gradually fading from the center to the surrounding areas.
3. Comparison and identification of sunlight exposure: After applying a fluorescent pen to the printed paper, place it in the sun to accelerate the reaction of the thermosensitive coating to light. Which type of paper turns black the fastest indicates a shorter shelf life.
