Thermal Paper Manufacturing Process

Thermal paper is a special paper that is widely used in fields such as receipt, label, and ticket printing. It has a unique heat-sensing property, which can produce images or text after being heated.

The manufacturing process of thermal paper includes several key steps. First, the pulp needs to be prepared, which is the basic raw material for making paper. Pulp is usually made from materials such as wood fibers or waste paper. The pulp is then mixed with water, strained, and drained through a screen to form the fibrous web of the paper.

Next, the web needs to be pressed and dried to remove excess moisture. This step is an important part of ensuring the quality and stability of the paper. The paper then goes through a coater to coat it. Coating agents often contain heat-sensitive chemicals such as heat-sensitive powders or heat-sensitive paints.

After coating, the paper needs to be dried and cured. This can be done with an oven or other drying equipment. During the drying process, heat-sensitive chemicals bind to the fibers of the paper to form a heat-sensitive layer. This layer is capable of producing a color change or image display when heated.

Finally, after cutting and winding, the thermal paper can be finished products. During the cutting process, the paper will be cut according to different size requirements. Winding is to roll paper into a roll for subsequent use and processing.

In general, the manufacturing process of thermal paper involves multiple steps such as pulp preparation, fiber web formation, coating, drying and curing, cutting, and winding. Precise control and efficient operation of these steps are critical to producing high-quality thermal paper. Through continuous technological innovation and process improvement, the thermal paper manufacturing industry can meet the growing market demand and provide reliable printing materials for various industries.
