How durable is the thermal paper? Is it waterproof and oil resistant

The durability and water and oil resistance of thermal paper vary depending on the type of paper, the quality of the paper and the environment in which it is used.

durability

The durability of thermal paper is mainly reflected in the preservation time of its writing. In general, the writing on thermal paper cannot be permanently preserved, and the length of preservation depends on the quality of the paper, the preservation method, and the environment in which it is used. Good quality thermal paper, under reasonable storage conditions, the writing can be stored for a long time, such as 5-10 years, or even longer. However, ordinary thermal paper may only last a few months to a year or so. In addition, the writing life of thermal paper is also affected by environmental factors such as light, heat, and humidity, so adverse environments such as direct sunlight, high temperature and humidity should be avoided.

Water and oil resistance

Thermal paper generally does not have a natural waterproof and oil-proof function. This is because thermal paper is a paper that uses the principle of thermal sensitivity and is heated and discolored under high pressure, and its surface does not form a waterproof and oil-proof coating. However, in order to meet specific application needs, such as catering, logistics and other fields, some manufacturers will carry out special treatment on thermal paper, such as coating treatment, to achieve a certain waterproof and oil-proof effect. The surface of this treated thermal paper is covered with a special coating to form a protective layer, thereby improving its water and oil resistance. However, it should be noted that even after special treatment, the waterproof and oil-resistant performance of thermal paper is limited, and it can not be soaked in water for a long time or in contact with a large amount of oil.

Sum up

In summary, the durability and water and oil resistance of thermal paper vary depending on the type of paper, quality and use environment. When selecting thermal paper, it should be selected according to the specific application needs. If you need long-term storage or waterproof and oil-proof application scenarios, you should choose good quality thermal paper or specially treated thermal paper, and pay attention to reasonable storage methods and use environment. At the same time, it is also necessary to note that the service life of thermal paper is limited and cannot be permanently stored.
