4 "x 6" inches Purple thermal label paper

Purple thermal label paper is a paper treated with a highly thermal sensitive coating, which is specially used in thermal printers and thermal fax machines. The following is a detailed introduction to the purple thermal label paper:

Definition and characteristics

Definition: Purple thermal label paper is coated with a layer of heat sensitive coating containing dark dyes (such as crystal violet lactone, etc.) and acidic substances, through thermal action to produce purple images or text paper.

Material characteristics: Purple heat-sensitive label paper is usually waterproof and oil-proof

Second, the working principle

The working principle of purple thermal label paper is based on thermal reaction. When the thermal paper encounters the heat generated by the print head of the thermal printer, a chemical reaction occurs between the dark dye and the acidic substance on the surface of the paper, which displays a purple image or text.

3. Scope of application

Purple thermal label paper is widely used in many fields, including but not limited to:

Supermarket and retail: used for electronic scale labels, price tags, etc.
