2、Are shopping receipts in shopping malls and supermarkets thermal paper?
Supermarket coupons are the most common thermal paper labels, usually white. Thermal paper is a kind of special high-quality paper. It is coated with chemical materials, which can change the color of paper due to heat, without using ink or printing ink. Thermal paper can be used as thermal printer, which is called thermal printing paper printer, small ticket paper printer, ticket printer, etc.
The basic principle of thermal printing paper is to coat the ordinary paper base with granular powder, which is composed of colorless phenolic dyes or other acidic substances, separated by the film and melted by the film. Under thermal conditions, the film melts and the powder mixes with the coloring reaction. Generally speaking, the color ink on the thermal printing paper is unstable and easy to disappear, making it difficult to save the contents of the document. This is why supermarket tickets are often difficult to see clearly.
