Will small rolls of thermal label paper produce any odor during the printing process?

Small rolls of thermal label paper may produce odors during the printing process. This odor mainly comes from special chemicals on the surface of thermal paper, which react chemically when exposed to heat, releasing an odor. The following is a detailed explanation of this phenomenon:

Composition and Reaction of Thermal Paper

Thermal paper structure: The surface of thermal paper or label paper is coated with a special chemical substance that undergoes a color change reaction at high temperatures, forming text or images.

Chemical reaction: When the coating of thermal paper is heated by the high temperature of the thermal print head, a chemical reaction occurs, and the coating quickly turns black or dark, which may release odors during this process.

The source and impact of odors

Source: The odor mainly comes from the chemical substances in the coating of thermal paper, which evaporate during the heating process.

Impact: Although these odors usually do not pose a direct threat to the human body, prolonged exposure to a large amount of printed odors in a confined space may cause discomfort, such as nausea and other symptoms.

Methods to reduce odors

Ventilation: When using a thermal printer, maintaining good indoor ventilation can help reduce the accumulation of odors.

Choose high-quality thermal paper: Poor quality thermal paper may contain more harmful chemicals, which can easily produce stronger odors. Therefore, choosing high-quality thermal paper can reduce the generation of odors to a certain extent.

Regularly clean the printer: Regularly cleaning the printer can remove dirt and residue inside the printer, reducing the source of odors.

In summary, small rolls of thermal label paper may indeed produce odors during the printing process. However, by taking appropriate measures such as maintaining ventilation, selecting high-quality thermal paper, and regularly cleaning the printer, the generation and accumulation of odors can be effectively reduced.
