What are the storage conditions of three heat-proof labels?

The storage conditions of the heat-resistant label paper are crucial to maintaining its quality and performance. In general, storage conditions should meet the following requirements:

1. Temperature and humidity

Temperature: The ideal storage temperature range is 23±2 ° C. Avoid prolonged exposure to high temperatures, especially above 50 ° C, because high temperatures will accelerate the aging of heat-sensitive coatings and affect the preservation performance of printed images.

Humidity: The relative humidity should be controlled at about 50±5%. Excessive humidity may lead to hygroscopic deformation of the paper, affecting the printing effect and subsequent use. At the same time, the humid environment may also promote the growth of mold, causing damage to the paper.

2. Lighting conditions

Avoid direct sunlight: Prolonged exposure to direct sunlight will accelerate the photochemical reaction of the heat-sensitive coating, causing the image to fade and blur. Therefore, when storing, the heat-sensitive label paper should be placed in a cool and dark place.

3. Chemicals and pollutants

Avoid contact with harmful substances: such as alcohol, volatile organic solvents, plasticizers, oils, etc., these substances may corrosion or dissolve the thermal sensitive coating, thus affecting the printing effect and preservation performance of the label paper.

Keep the environment clean: The storage environment should be kept clean and tidy to avoid pollution from dust and other impurities.

4. Packaging and stacking

Appropriate packaging: The heat-sensitive label paper should be sealed with appropriate packaging materials to prevent the external environment from affecting it. The packaging should be marked with product name, specifications, production date, expiration date and other information.

Reasonable stacking: Avoid being too heavy or too tight when stacking to prevent deformation or damage to the paper. At the same time, the stacking height and method should also meet the requirements on the packaging.

5. Storage period

Follow the manufacturer's recommendations: Different heat-sensitive labels may have different storage period requirements, which should be followed by the product manual or the manufacturer's recommendations. In general, under appropriate storage conditions, the storage period of the three heat-resistant label paper can reach one year or even several years.

6. Regular inspection

Periodically check storage conditions: Periodically check and maintain the storage environment to ensure that conditions such as temperature, humidity, and illumination meet requirements.

Check the status of the label: Periodically check the status of the heat-sensitive label, such as whether there is deformation, fading, mildew, etc. If any problem is found, handle it promptly and replace the label with a new one.

To sum up, the storage of three heat-sensitive labels should strictly control the temperature, humidity, lighting conditions and avoid exposure to harmful substances and other adverse factors. Proper packaging and stacking as well as regular inspection and maintenance measures can ensure that the label paper maintains good quality and performance during storage.
