How to avoid fading or aging of BOPP colored synthetic paper during storage?

To avoid fading or aging of BOPP colored synthetic paper during storage, the following measures can be taken:

1、 Control storage environment

Temperature:

Store BOPP colored synthetic paper in a cool environment and avoid high temperatures. High temperature can accelerate the reaction of chemical substances inside the paper, leading to color fading or aging. It is recommended to keep the storage temperature at room temperature or slightly lower, avoiding exceeding 30 ℃.

Humidity:

Maintain moderate humidity in the storage environment and avoid being too humid or dry. Excessive humidity may cause paper to become damp, affecting printing quality and durability; Low humidity may cause paper to become dry and fragile. It is recommended to use a dehumidifier or humidifier to control humidity and maintain it within the relative humidity range of 40% -60%.

illumination:

Avoid prolonged exposure of BOPP colored synthetic paper to sunlight or strong light. Ultraviolet radiation has a significant impact on the color stability of paper, and prolonged exposure can cause color fading. Therefore, paper should be stored in a dark environment or covered with shading materials.

2、 Choose an appropriate storage container

Using sealed containers:

Choose a well sealed container to store BOPP colored synthetic paper to prevent external factors such as air, dust, and moisture from entering. Sealed containers can effectively protect paper from environmental factors.

Avoid using transparent containers:

Transparent containers may allow ultraviolet rays to penetrate, causing damage to paper. Therefore, it is recommended to choose opaque storage containers.

3、 Regular inspection and maintenance

Regularly check the paper condition:

Regularly check the condition of BOPP colored synthetic paper, including color, glossiness, toughness, etc. If signs of fading, aging, or damage are found on the paper, timely measures should be taken to deal with them.

Avoid prolonged accumulation:

Avoid stacking paper together for a long time to prevent indentation or deformation. It is recommended to regularly flip the paper to maintain its flatness and looseness.

4、 Pay attention to the usage period

Understand the usage period:

BOPP colored synthetic paper usually has a certain service life. When purchasing, it is important to understand the shelf life of the paper and use it up within the shelf life.

Avoid expired use:

Avoid using expired BOPP colored synthetic paper. The performance of expired paper may have declined and cannot meet the usage requirements.

In summary, by controlling the storage environment, selecting appropriate storage containers, conducting regular inspections and maintenance, and paying attention to the expiration date, BOPP colored synthetic paper can effectively avoid fading or aging during storage. These measures help maintain the performance and quality of paper, extending its lifespan.
