What is the oil resistance of color thermal label paper?

The oil resistance of color thermal label paper varies according to the type of product, production process and coating material. In general, ordinary color thermal label paper does not have oil-proof performance, but there are also some specially designed color thermal label paper on the market, which achieves a certain oil-proof effect through coating treatment and other ways.

Oil resistance of ordinary color thermal label paper

Ordinary color thermal label paper is mainly used for marking, printing and other conventional purposes, and its surface coating is mainly concerned with printing effect and color brightness, rather than oil resistance. Therefore, when in contact with oily substances, these labels may penetrate, blur and even fall off, affecting their use effect.

Special oil-proof color heat-sensitive label paper

In order to meet the needs of specific industries, such as catering, logistics and other fields, some color thermal label paper with oil-proof performance has appeared on the market. These labels are usually treated with special coating materials and techniques to improve their oil resistance. For example, some manufacturers will cover the surface of thermal paper with a special waterproof and oil-proof coating to form a protective layer, which effectively prevents the penetration and pollution of oily substances.

Oil resistance evaluation

The evaluation of oil resistance is usually done through experimental testing. For example, oil resistance tests can be carried out, and indicators such as image retention and color change can be observed after the label paper is exposed to the oil environment for a period of time. In general, color thermal label paper with oil resistance will show better image retention and color stability in oil resistance tests.

Application scenario

The color heat-sensitive label paper with oil-proof performance has a wide application prospect in catering, logistics and other fields. In the catering industry, these labels can be used to print dish labels, food packaging labels, etc., effectively preventing label blurring or falling off caused by oil pollution. In the logistics industry, they can be used to print express waybills, cargo labels, etc., ensuring the clarity and readability of labels during transportation.

Conclusion

In summary, the oil-proof performance of color thermal label paper varies depending on the type of product and the coating material. When selecting color thermal label paper, it should be selected according to the specific application needs to ensure that its oil resistance meets the requirements of use. At the same time, with the continuous progress of technology and the continuous development of the market, there may be more color thermal label products with excellent oil resistance in the future.
