Are small rolls of heat-sensitive label paper waterproof and oil-proof?

Whether the small roll of heat-sensitive label paper is waterproof and oil-proof mainly depends on its specific material and treatment process.

In general, ordinary heat-sensitive paper label paper does not have the ability to waterproof and oil-proof. This is because thermal paper is a paper that uses the principle of thermal sensitivity and is thermologically discolored under high pressure, and its surface is not specially treated to resist the erosion of moisture and grease. Therefore, when used in a wet or greasy environment, ordinary thermal paper labels may become discolored, fuzzy or even unprintable.

However, in order to meet the needs of specific industries, such as catering, logistics and other fields, there are also some specially treated three-proof (waterproof, oil-proof, scratchproof) thermal label paper on the market. These labels are covered by a special coating on their surface to form a protective layer, so that it has a certain waterproof and oil-resistant ability. This heat-resistant label paper can keep the label content clearly visible even in wet or greasy environments.

Therefore, for the small roll of heat-sensitive label paper can be waterproof and oil-proof, it needs to depend on its material and treatment process. If the label paper is clearly marked as three heat-proof label paper, then it usually has the ability to waterproof and oil-proof; If the label paper has not been specially treated, it does not have these capabilities.

When selecting a small roll of thermal label paper, you are advised to select an appropriate label type based on the specific environment and requirements to ensure the effectiveness of the label. At the same time, during use, attention should also be paid to avoid scratching, friction and other problems, so as not to affect the waterproof and oil-proof function of the label paper.
