What are the common self-adhesive labels?

Common self-adhesive labels are made of PET material and thermal paper, both of which are suitable for different types of label printers. Usually, printers that print PET material self-adhesive labels are It is a thermal transfer printing machine. The printers that print thermal stickers are usually thermal label printers.

The printing principle of thermal transfer PET self-adhesive labels is to use a special ribbon to heat the toner coating on the ribbon through a working principle similar to the print head of a fax machine. When transferred to paper or other types of materials, the coating material on the ribbon can be selected as needed to produce strong adhesion. Coupled with the choice of printing media, it can ensure that the printed handwriting is not affected by external influences. Influence.

PET self-adhesive label

Thermal self-adhesive label is a special kind of coated paper, which is made of ordinary paper as the paper base and coated with a layer of heat-sensitive In the chromogenic layer, chemical reactions are in a "latent" state. When the thermal paper encounters a heated print head, a chemical reaction occurs between the color developer and the colorless dye where the print head prints, causing it to change color and form graphics and text.

Thermal paper self-adhesive labels

Compare the advantages and disadvantages of thermal transfer label printers and thermal label printers:

Thermal transfer technology prints larger materials Partially relying on imported materials to achieve printing effects, the cost is higher than thermal printing, and the price of the label tape required by the thermal transfer label printer is slightly higher;

In terms of printing effect, the thermal transfer label printer The printing effect is more weather-resistant, the label content can be waterproof and oil-proof, and the lasting and clear effect is stronger.
