Will the printed information on BOPP colored thermal sensitive synthetic paper fade?

There is indeed a possibility of fading in the printed information of BOPP color thermal synthetic paper. This is mainly due to the special properties of thermal paper and the influence of various external factors. The following is a detailed analysis of this issue:

Reasons for fading

Reversibility of color reaction in thermal paper:

The color reaction of thermal paper is based on the color change of chemical substances in the thermal coating when heated. However, this color reaction is reversible, meaning that colored products will decompose to varying degrees on their own, causing the color of the handwriting to gradually fade.

External environmental factors:

Light exposure: Prolonged exposure to strong light can accelerate the decomposition of color products and accelerate fading.

Temperature: High temperature environments can also promote the decomposition of color products, leading to fading of handwriting.

Humidity: Excessive humidity may cause paper to become damp, thereby affecting the clarity of printed content.

Chemical substances: Some chemicals may damage the coating on the surface of the paper, causing the printed content to fade.

Improper storage conditions:

BOPP color thermosensitive synthetic paper should be stored in a dry, ventilated, and dust-free environment, avoiding direct sunlight and high temperature and humidity conditions. Improper storage environment may lead to a decrease in material performance and affect printing results.

Material quality:

There may be color differences in BOPP colored thermosensitive synthetic paper from different batches or under different production conditions, resulting in inconsistent colors of printed products, and low-quality thermosensitive paper is more prone to fading.

Preventive measures

To avoid fading of printed information on BOPP color thermal sensitive synthetic paper, the following measures can be taken:

Choose high-quality thermal paper:

When making a purchase, pay attention to the quality of the paper and choose high-quality and durable BOPP color thermal synthetic paper.

Control storage conditions:

Store thermal paper in a dry, ventilated, and dust-free environment, avoiding direct sunlight and high temperature and humidity conditions.

Avoid contact with chemicals:

Ensure that thermal paper does not come into direct contact with chemicals to prevent damage to the coating on the paper surface.

Correctly set up and use the printer:

Regularly inspect and maintain printing equipment to ensure its cleanliness and proper operation.

Correctly set various parameters of the printer, such as printing speed, printing density, etc., to achieve the best printing effect.

Seal packaging with transparent plastic bags or folders:

Seal and package the printed BOPP color thermosensitive synthetic paper in a transparent plastic bag or folder to prevent dust and other contaminants from entering.

In summary, there is a possibility of fading in the printed information of BOPP color thermal synthetic paper. However, by selecting high-quality thermal paper, controlling storage conditions, avoiding chemical contact, correctly setting up and using printers, and using transparent plastic bags or sealed folders for packaging, the storage time of printed information can be effectively extended and the risk of fading can be reduced.
