What chemicals can cause damage to color thermal label paper?

The color and performance of color thermal label paper can be affected by a variety of chemicals, the following are some common chemicals that can cause damage to color thermal label paper:

1. Strong acid and alkali substances

Impact: Strong acids or alkali substances are strongly corrosive and can destroy the chemical structure in the heat-sensitive coating, resulting in color fading or coating damage.

Examples: hydrochloric acid, sulfuric acid, sodium hydroxide, etc.

2. Oxidants

Effects: Oxidizing agents can react with chemicals in the heat-sensitive coating, resulting in color changes or decreased coating performance.

Examples: hydrogen peroxide, potassium permanganate, etc.

3. Solvent

Effects: Certain solvents are able to dissolve chemicals in the heat-sensitive coating, causing the color to fade or the coating to peel off.

Examples: alcohol, acetone, toluene, etc.

4. Grease and grease stains

Impact: Grease stains may penetrate the interior of the heat-sensitive coating and destroy the structure of the coating, resulting in color changes or coating damage.

Examples: edible oil, oil, lubricating oil, etc.

5. Tape and other stickings

Effects: Tape and other pastes may contain substances that can react chemically with the heat-sensitive coating, causing color fading or coating damage.

Examples: Scotch tape, double-sided tape, label paper, etc.

6. Ultraviolet light

Impact: Although UV light is not a chemical, it is able to destroy the chemical structure in the heat-sensitive coating, causing the color to fade.

Example: ultraviolet rays in sunlight.

Preventive measure

In order to avoid damage caused by these chemicals to color thermal label paper, the following precautions can be taken:

Choose high-quality thermal paper: Buy thermal paper products that are reliable and suitable for your specific application.

Reasonable storage: Store the label paper in a cool, dry, and light-free environment to avoid contact with the above chemicals.

Correct use: When using the label paper, avoid direct contact with grease stains, tapes and other adhesive materials.

Protective coating: You can consider coating a protective layer on the surface of the label paper to improve its chemical corrosion resistance.

In summary, a variety of chemicals can cause damage to color thermal label paper. Therefore, it is necessary to avoid contact with these chemicals during use and storage, and take appropriate precautions to protect the quality and performance of the label paper.
