What are the main raw materials for producing PET thermosensitive matte silver paper?

The main raw materials for producing PET thermosensitive matte silver paper include the following categories:

1、 Polyester film (PET)

Polyester film is the basic material of PET thermosensitive matte silver paper, which has high strength, high modulus, and good weather resistance. As the base material of the label, it provides stable physical and chemical properties for the label.

2、 Thermal sensitive coating material

Thermal sensitive coating is a key component for PET thermal sensitive matte silver paper to achieve thermal printing. This type of coating typically contains thermosensitive color changing pigments, resins, and other additives that can quickly change color when heated, resulting in clear images or text. The quality of thermal sensitive coatings directly affects the printing effect and durability of labels.

3、 Matte silver special coating

The special coating of matte silver is the key to presenting a matte silver feel on PET thermosensitive matte silver paper. This coating usually has a uniform silver polyester polymer material, which can give the label a high-end and professional appearance. At the same time, the matte silver coating also has certain waterproof, oil resistant, and chemical corrosion resistant properties, improving the durability of the label.

4、 Adhesive

Adhesive is the key to firmly bonding PET thermosensitive matte silver paper with various substrates such as paper, plastic, metal, etc. The choice of adhesive directly affects the adhesion and peel strength of the label. High quality adhesives can ensure that labels maintain a stable bonding effect in various environments.

5、 Other auxiliary materials

During the production process, it may also be necessary to use some auxiliary materials, such as base paper, release film, etc. These materials play an important role in the production, processing, and use of labels, such as protecting labels, facilitating printing and pasting, etc.

In summary, the main raw materials for producing PET thermosensitive matte silver paper include polyester film, thermosensitive coating materials, matte silver special coatings, adhesives, and other auxiliary materials. The selection and ratio of these raw materials will directly affect the quality and performance of PET thermosensitive matte silver paper.
