What is thermal paper

Thermosensitive paper is a specially processed paper characterized by the ability to quickly change color when subjected to heat. This type of paper is coated with a layer of thermosensitive coating on high-quality base paper, which is composed of various chemical substances, including colorless dyes, colorants, sensitizers, fillers, adhesives, stabilizers, and lubricants. The manufacturing process of thermosensitive paper is complex and requires high technical requirements. twelve
The application of thermal paper is very extensive, and it is used in commercial, medical, aviation, retail and other fields. For example, in commercial activities, thermal paper is used to make trademarks, cash register receipts, etc; In the medical field, it is used as an electrocardiogram chart, thermal instrument recording paper, and so on. In addition, thermosensitive paper is also widely used in households and schools, such as error printing paper.
According to different functions and scenarios, thermal paper can be divided into various types. Ordinary thermal paper and three proof (waterproof, oil resistant, and wear-resistant) thermal paper are the two main classifications. The three proof thermosensitive paper is coated with a protective layer on the thermosensitive color layer, making it more durable. In addition, according to different usage scenarios, thermal paper can also be divided into two types: commercial and household. Commercial thermal paper is often used for printing receipts in commercial supermarkets, while household paper is commonly used for printing student mistakes.
When choosing thermosensitive paper, it is necessary to consider its specifications and dimensions. Currently, there are common thermosensitive papers in the 57mm and 80mm series, as well as the distinction between the presence and absence of tube cores. The selection of these sizes and types depends on specific application requirements and equipment requirements.
