What impact do the storage conditions of BOPP color synthetic paper have on its printing effect?

The storage conditions of BOPP color synthetic paper have a significant impact on its printing effect. The following is a specific analysis of the impact of storage conditions on printing performance:

1、 Temperature and humidity

Temperature:

High temperature environment may cause chemical reactions in the thermal sensitive coating of BOPP color synthetic paper, accelerating the aging process and affecting its printing effect. Specifically manifested as color fading, unclear color rendering, or uneven color distribution.

Although a low-temperature environment is relatively safe, excessively low temperatures may cause paper to become brittle, increasing the risk of damage during the printing process.

Humidity:

Excessive humidity can cause paper to absorb too much moisture, leading to paper expansion and deformation, which in turn affects print quality and paper flatness.

If the humidity is too low, it may make the paper too dry, increase the static effect, and cause problems such as paper adhesion or paper jam during the printing process.

2、 Light and ultraviolet radiation

Long term direct sunlight or strong light exposure can cause photochemical reactions in the thermal sensitive coating on the surface of BOPP colored synthetic paper, leading to color fading and accelerated aging. Ultraviolet radiation is one of the main triggers of photochemical reactions, therefore, when storing paper, direct exposure to sunlight or strong light should be avoided.

3、 Dust and pollutants

Dust and pollutants present in the storage environment may adhere to the surface of BOPP color synthetic paper, affecting the normal operation of the print head and leading to a decrease in print quality. These pollutants may also clog the print heads of the printer, increasing maintenance costs. Therefore, the storage environment should be kept clean to avoid the intrusion of dust and pollutants.

4、 Storage time and batch differences

Storage time:

BOPP colored synthetic paper has a certain shelf life. Long term storage may lead to paper aging and a decrease in the performance of thermal sensitive coatings, thereby affecting the printing effect. Therefore, it is recommended to purchase and store paper reasonably according to actual needs to avoid long-term backlog.

Batch differences:

There may be slight differences in the formula and thickness of the thermal sensitive coating between different batches of BOPP colored synthetic paper. These differences may result in different printing effects. Therefore, when using, attention should be paid to distinguishing batches and adjusting printing parameters according to actual situations.

In summary, in order to ensure the printing effect of BOPP color synthetic paper, it should be stored in a cool, dry, and dark environment, and the storage environment should be kept clean. Meanwhile, pay attention to the shelf life and batch differences of the paper, and adjust the printing parameters according to the actual situation. These measures will help extend the lifespan of paper and improve print quality and efficiency.
