Does the color of BOPP synthetic paper fade with light?

Whether the color of the BOPP synthetic paper will fade with the light depends on a number of factors, including the material of the synthetic paper, the production process, the pigment or dye used, and the external light conditions.

Material and production process

BOPP synthetic paper is a new kind of material which is made of polypropylene (PP) as the main raw material and processed by bidirectional drawing. It combines the characteristics of plastic and paper, with light specific gravity, high strength, tear resistance, good printability, shading, UV resistance and other advantages. However, different production processes and raw material formulations may have an impact on the light resistance of synthetic paper.

Pigments and dyes

The color of synthetic paper is usually given by pigments or dyes. The light fastness of the pigment directly affects the fading of the product. Inorganic pigments usually have better light and heat resistance, while organic pigments may change their molecular structure under light or high temperature conditions, resulting in paloration or fading. Therefore, if the synthetic paper uses organic pigments with poor light resistance, its color may gradually fade under long periods of light.

External light condition

The intensity and duration of external light is also an important factor affecting the color fading of synthetic paper. Strong sunlight and prolonged exposure speed up the decomposition and fading process of pigments or dyes. Therefore, colored BOPP synthetic paper used outdoors or exposed to sunlight for a long time is more likely to fade.

Comprehensive consideration

In summary, whether the color of the color BOPP synthetic paper will fade with the light depends on the combined effect of multiple factors. In order to improve the light fastness of synthetic paper, pigments or dyes with good light fastness can be selected in the production process, and an appropriate amount of light stabilizer such as ultraviolet absorber can be added. In addition, try to avoid long-term exposure to strong sunlight during use, which can also effectively extend the retention time of synthetic paper color.

Since the performance of specific products may vary due to factors such as manufacturers, production processes and raw material formulations, it is also necessary to judge according to the technical specifications and instructions of specific products in practical applications. If you cannot obtain the relevant information from the product description, it is recommended to consult the manufacturer or a professional in the relevant field.
