Can heat-sensitive label paper be oxidized？

Thermal label paper does oxidize. The following is a detailed analysis of the oxidation problem of thermal label paper:

First,Reasons for oxidation

1.Environmental factors: Thermal label paper is affected by external environment such as temperature and humidity, and is easy to be oxidized. Exposure to direct sunlight or strong light for a long time will also cause the photosensitive performance of thermal label paper to decay, and label printing will become blurred.

2.Chemical substances: The influence of chemical substances on thermal label paper will also lead to its failure. For example, when placed in an acidic environment, the label color will turn red or yellow. The oxygen in the air is also one of the important factors leading to the oxidation of thermal paper.

Second,Oxidation performance

1.Color change: After the thermal label paper is oxidized, its color may change, such as fading, yellowing, etc.

2.Decline in print quality: The print quality of the oxidized thermal label paper will be significantly reduced, the handwriting is no longer clearly visible, and there may even be fuzzy, incomplete and other phenomena.

Third, the method of extending the service life

1.Storage environment: Store heat-sensitive labels in a cool, dry, and dark environment to avoid long-term exposure to high temperature, high humidity, or direct sunlight.

2.Use antioxidants: Some high-end thermal paper products will add antioxidants to extend their service life. Antioxidants can inhibit the production of free radicals, stabilize the chemical structure of the paper, and prevent oxidative degradation.

3.Choose high-quality products: When purchasing, choose thermal label paper produced by reliable quality and reputable brands and manufacturers to ensure that the product has good chemical resistance and oxidation resistance.

Fourth,Matters needing attention in practical application

1.Timely use: The heat-sensitive label paper after opening the package should be used as soon as possible to avoid long-term exposure to the air leading to oxidation.

2.Avoid contact with chemical substances: During use and storage, avoid contact with corrosive substances such as strong acids and alkalis.

3.Regular inspection: For long-term storage of heat-sensitive label paper, quality inspection should be carried out regularly to ensure that its printing effect and physical properties meet the requirements of use.

In summary, the thermal label paper will indeed be oxidized, and the oxidation process is affected by a variety of factors. In order to extend its service life and maintain print quality, it is necessary to pay attention to the storage environment, the use of antioxidants, and the selection of high-quality products.
