The oil-proof function of the three heat-sensitive label paper is achieved by what process?

The oil-proof function of the three heat-sensitive label paper is mainly achieved through the following processes:

1. Add waterproof and oil-proof coating

Waterproof and oil-proof coating material: Three heat-proof label paper is coated with a special waterproof and oil-proof coating on top of the heat-sensitive hair color layer. This coating is composed of specific chemicals that have excellent oil resistance and can effectively prevent grease contamination and erosion of the heat-sensitive coating.

Coating action: This layer of waterproof and oil-resistant coating can not only block the penetration of water, protect the heat-sensitive coating from water erosion, but also absorb oil and avoid oil adhesion to the label surface, thus maintaining the clarity and readability of the label.

2. Advanced production technology

Coating technology: In the production process, the use of advanced coating technology, the waterproof and oil-proof coating evenly coated on the thermal color layer, to ensure the thickness and uniformity of the coating to achieve the best state.

Quality control: Through strict quality control measures, to ensure that the oil resistance of each roll and each sheet of three heat-proof label paper meet the standard requirements.

3. Use of environmentally friendly materials

Environmentally friendly glue: The adhesive part of the three heat-resistant label paper is an environmentally friendly type of glue, which ensures the viscosity at the same time, but also meets the environmental requirements, and will not cause pollution to the environment.

Recyclable reuse: Some of the three heat-resistant label paper is made of environmentally friendly materials, which not only has excellent performance during use, but also can be recycled after use, reducing the impact on the environment.

4. Practical application effect

Oil proof test: In practical applications, the three heat-proof label paper can withstand the test of various oils, whether it is cooking oil, oil or other industrial oils, and can maintain the clarity and integrity of the label to a certain extent.

Widely used: Due to its excellent oil proof performance, the three heat-proof label paper has been widely used in many fields such as catering, supermarkets, and medical treatment. For example, in the catering industry, the three heat-sensitive label paper can be used for the logo on the takeaway packaging, even if it encounters grease, it will not easily fall off or blur.

In summary, the oil-proof function of the three heat-proof label paper is mainly achieved by adding a waterproof and oil-proof coating, adopting advanced production processes and using environmentally friendly materials. These measures work together to make the three heat-proof label paper perform well in oil-proof performance and meet the needs of use in a variety of complex environments.
