Will the performance of BOPP thermal sensitive synthetic paper deteriorate after long-term storage?

After prolonged storage, the performance of BOPP thermal sensitive synthetic paper may indeed deteriorate. This decline may be influenced by multiple factors, and the following is a detailed analysis of this phenomenon:

1、 Degradation of thermal sensitive coating performance

The thermosensitive coating of BOPP thermosensitive synthetic paper is a key component responsible for color changes to display text and images when heated. However, prolonged storage may cause changes in the chemical composition of the thermosensitive coating, thereby affecting its color rendering performance and stability. The specific manifestation is that the printed handwriting or image color becomes lighter, unclear, and may even fade or disappear.

2、 Changes in physical properties of paper

Long term storage may also cause changes in the physical properties of BOPP thermosensitive synthetic paper. For example, the toughness, strength, and tear resistance of paper may decrease, making it more susceptible to damage. In addition, the moisture absorption of paper may also change, making it more prone to water absorption and deformation in humid environments, or more prone to dehydration and brittleness in dry environments.

3、 The impact of storage conditions

The storage conditions also have a significant impact on the performance degradation of BOPP thermosensitive synthetic paper. If the humidity in the storage environment is too high or too low, it may accelerate the degradation of paper performance. Excessive humidity may cause paper to absorb water and deform, while low humidity may cause paper to lose water and become brittle. In addition, the temperature of the storage environment is also important. Excessive temperature may accelerate the chemical reaction of the thermosensitive coating, leading to faster performance degradation.

4、 Preventive measures

In order to extend the storage time of BOPP thermal sensitive synthetic paper and slow down performance degradation, the following preventive measures can be taken:

Choose a suitable storage environment: Store BOPP thermosensitive synthetic paper in a dry, cool, and well ventilated environment, avoiding direct sunlight and high temperature and humidity.

Using sealed packaging: Place the paper in a sealed bag or box to reduce contact with air, thereby slowing down the rate of oxidation and chemical reactions.

Regular inspection: Regularly inspect the stored BOPP thermosensitive synthetic paper to promptly identify and address any potential issues such as deformation, discoloration, etc.

In summary, the performance of BOPP thermosensitive synthetic paper may deteriorate after long-term storage, but this deterioration can be mitigated by selecting appropriate storage environments, using sealed packaging, and regular inspections as preventive measures.
