What is the working principle of PET thermal sensitive matte silver paper?

The working principle of PET thermal matte silver paper is mainly based on thermal printing technology. The following is a detailed explanation of its working principle:

1、 Fundamentals of thermal printing technology

Thermal printing technology is a technique that generates images and text by heating the print head to chemically react the thermal coating on thermal paper. This technology has the advantages of fast speed, low noise, and clear printing, and is widely used in various label printing occasions.

2、 Structure and characteristics of PET thermosensitive matte silver paper

PET thermal matte silver paper is an advanced label material that combines thermal printing technology with matte silver texture. Its structure usually includes a layer of PET substrate, a layer of silver special coating, and possible adhesive layer and backing paper. The matte silver finish gives the paper a high-end and professional appearance, while the sub silver coating also enhances the durability and printing effect of the paper.

3、 Detailed explanation of working principle

Heating process:

When PET thermal matte silver paper passes through a thermal printer, the semiconductor heating element on the print head heats the surface of the paper.

The temperature and time of heating are controlled by the printer to ensure that the thermal sensitive coating can undergo appropriate chemical reactions.

Chemical reaction:

During the heating process, the chemical substances in the sub silver special coating on the surface of PET thermosensitive matte silver paper will react.

These chemicals typically include dark dyes and acidic substances. When the temperature rises, the dark dye and acidic substances will melt into a liquid and undergo a chemical reaction to produce visible colors.

Image and text generation:

By controlling the heating mode and temperature of the print head, clear images and text can be generated on PET thermal matte silver paper.

These images and text are directly generated on the surface of the paper through chemical reactions, without the need for additional printing consumables.

4、 Application and advantages

The working principle of PET thermosensitive matte silver paper makes it have a wide range of application prospects. Its excellent durability, printing effect, and environmental performance make it an ideal choice for various occasions that require high-quality labels. For example, in the automotive industry, retail industry, logistics industry, and medical industry, PET thermal matte silver paper is widely used in parts identification, price labeling, barcode and QR code printing, and other fields.

In summary, the working principle of PET thermal sensitive matte silver paper is based on thermal printing technology. By heating the print head, the thermal sensitive coating on the surface of the paper undergoes a chemical reaction, resulting in clear images and text. This working principle gives it broad application prospects and significant advantages.
