What are the main components of PET matte silver thermal paper?

PET matte silver thermal paper is an advanced label material that combines thermal printing technology with matte silver texture. Its main components can be analyzed from the following aspects:

1、 Basic materials

PET (Polyethylene terephthalate): The basic material of PET matte silver thermal paper is PET, which is a polyester film with excellent physical and chemical properties, such as high temperature resistance, waterproof and oil resistance, and strong chemical stability. These characteristics make PET an ideal material for producing high-quality label paper.

2、 Thermal sensitive coating

Colorless dye: Thermal paper displays color when exposed to heat due to a chemical reaction between the colorless dye in its coating and the color developer. In PET matte silver thermal paper, this colorless dye is also used, and commonly used dyes include colorless benzoyl methylene blue (BLMB).

Color developer: Color developer is another key component in thermal sensitive coatings, which reacts with colorless dyes to produce color. Common colorants include para hydroxybenzoic acid and its esters (PHB, PHB), salicylic acid, etc.

Other additives: In addition to colorless dyes and color developing agents, thermosensitive coatings may also contain sensitizers, fillers, adhesives, stabilizers, lubricants, and other additives to improve the performance of thermosensitive paper, such as increasing print clarity and extending storage time.

3、 Matte silver texture treatment

Surface treatment: In order to give PET matte silver thermal paper a matte silver feel, special treatment may be required on the surface of the PET film, such as using a matte coating or embossing process. These treatments can not only enhance the visual effect of the paper, but also increase its wear resistance and fingerprint resistance.

In summary, the main components of PET matte silver thermal paper include PET base material, thermal sensitive coating (colorless dye, color developer, and other additives), and special treatment layer that gives matte silver feeling. These components together make up PET matte silver thermal paper, which has excellent printing performance and visual effects, and is widely used in label production in various industries.
