What special treatment can be performed on the surface of color thermal label paper?

The surface of the color thermal label paper can be subjected to a variety of special treatments to improve its performance, adaptability and service life. Here are some common special treatments:

1. Corona treatment

Objective: To increase the polarity of paper surface by corona discharge, so as to improve the adhesion of ink or other coatings.

Effect: The surface of the paper treated with corona can better absorb ink, making the printing effect clearer and fuller, while reducing the phenomenon of shedding or blurring in the printing process.

2. Flame impact treatment

Objective: To change the physical and chemical properties of paper surface by using the high temperature impact of flame, improve the adhesion and printing effect of ink.

Effect: The flame impact treatment can rapidly improve the roughness and polarity of the paper surface, so that the ink can be more firmly attached to the paper, thereby improving the quality of the print.

3. Plasma treatment

Objective: To change the surface structure and properties of paper by bombarding the surface with high-energy particles in plasma, improve the surface energy and printing adhesion.

Effect: Plasma treatment can form a layer of fine concave and convex structure on the surface of the paper, increase the contact area between the paper and the ink, thereby improving the adhesion of the ink and the clarity of the print.

4. Waterproof and oil-proof treatment

Objective: To make the color heat-sensitive label paper waterproof and oil-proof by coating it with a special waterproof and oil-proof coating.

Effect: The water-resistant and oil-resistant paper can maintain the clarity and readability of the label in wet or oily environments, and is suitable for a variety of special scenarios.

5. Anti-stick treatment

Objective: By coating a layer of anti-stick agent or other treatment methods, reduce the adhesion of paper surface and prevent adhesion with other materials.

Effect: The anti-stick treatment can make the color thermal label paper not easy to adhere to other materials during storage, transportation and use, and maintain the integrity and readability of the label.

6. Wear resistant treatment

Objective: To improve the wear resistance of paper by increasing the hardness of paper surface or coating with a wear-resistant coating.

Effect: wear-resistant treatment can make the color thermal label paper is not easy to be worn or scratched during use, extending the service life of the label.

7. Uv curing treatment

Objective: To cure the coating quickly by ultraviolet irradiation and improve the hardness and adhesion of the coating.

Effect: UV curing treatment can make the coating on the surface of the color thermal label paper harder and wear-resistant, while improving the adhesion of the ink and the clarity of the print.

8. Back coating and pre-coating treatment

Objective: To improve the smoothness, ink absorption and other properties of paper by applying back and pre-coating.

Effect: The back coating and pre-coating treatment can make the surface of the color thermal label paper more flat and smooth, improve the clarity and quality of the print. At the same time, the pre-coating can also fill the fiber surface, improve the smoothness of the base paper, and thus improve the printing effect.

These special processing methods can be selected and applied according to different application scenarios and needs to improve the performance and adaptability of color thermal label paper.
