What is the waterproof and oil-proof performance of the round color copper plate label paper?

The waterproof and oil-proof properties of circular color copperplate label paper mainly depend on its surface treatment and material characteristics.

Water resistance

Basic waterproof: coated paper itself has certain waterproof properties, mainly due to its surface after coating and other processes to form a layer of coating. This layer of coating can prevent water from penetrating into the inside of the paper to a certain extent, thus playing a certain waterproof role. However, this waterproof performance is not absolute, especially in the case of a lot of moisture, coated paper may be deformed, soft and other bad conditions.

Enhanced water resistance: If a more thorough waterproofing treatment is required for coated paper, the method of surface coating treatment can usually be used. By covering the surface of coated paper with a waterproof material, its waterproof performance can be significantly improved. This treatment method is also often used in the production of circular colored copper plate label paper to meet the waterproof needs of specific occasions.

Oil resistance

Basic oil proof: coated paper itself does not have oil proof function. Because paper is woven from fibers, it is inherently hydrophilic, so it does not have the ability to resist oil penetration. If the content printed directly on coated paper comes into contact with grease, it is easy to leave traces.

Enhanced oil resistance: In order to improve the oil resistance of coated paper, surface treatment is also required. Common treatment methods include coating treatment and composite treatment. Coating treatment is to spray oil-proof paint on the surface of coated paper to form an oil-proof layer; The composite treatment is the composite processing of coated paper and oil-proof material. These treatments can effectively enhance the oil resistance of coated paper, so that it is suitable for occasions that need to resist oil pollution.

In summary, the waterproof and oil-proof performance of circular color copperplate label paper depends on its surface treatment and material characteristics. In the absence of special treatment, its water resistance is limited and it does not have oil resistance. However, through appropriate surface treatment methods, its waterproof and oil-proof performance can be significantly improved to meet the needs of different occasions.

It should be noted that different manufacturers and brands of round color copperplate label paper may have differences in waterproof and oil-proof performance, and the specific performance needs to refer to the product description and test report. At the same time, care should be taken to avoid long-term contact with a large amount of water or grease during use, so as not to affect the performance and service life of the label paper.
