What issues should be noted during the storage of BOPP colored synthetic paper?

In the process of storing BOPP color synthetic paper, the following key issues need to be noted to ensure that the quality and performance of the paper are not compromised:

1、 Storage environment

Dry and ventilated: BOPP color synthetic paper should be stored in a dry environment to avoid moisture causing paper deformation or affecting printing results. Meanwhile, maintaining ventilation can prevent paper from becoming moldy or deteriorating due to long-term sealed storage.

Avoid direct sunlight: Prolonged exposure to direct sunlight may cause paper to fade or age, so direct exposure to sunlight should be avoided. Choose a cool and shaded place to reduce the damage of light to the paper.

Dust and pollution prevention: The storage environment should be kept clean to prevent dust and pollutants from adhering to the paper. Dust covers or sealed bags can be used to protect paper and reduce the possibility of contamination.

2、 Storage conditions

Temperature control: Avoid storing BOPP colored synthetic paper in environments with excessively high or low temperatures. High temperatures may cause paper to soften and deform, while low temperatures may make paper brittle and fragile. Generally speaking, room temperature environment (such as 20-25 ℃) is more suitable.

Humidity control: Humidity is equally important for the preservation of paper. Excessive humidity can cause paper to absorb water and expand, affecting printing quality and paper durability. It is recommended to control the humidity within the range of 50% to 60% relative humidity.

3、 Storage method

Flat storage: To avoid paper deformation or damage, it is recommended to store BOPP colored synthetic paper flat to avoid stacking too high or being subjected to heavy pressure.

Avoid long-term storage: Although BOPP color synthetic paper has some durability, long-term storage may cause paper aging or affect printing results. Therefore, it is recommended to purchase and store paper reasonably according to actual needs to avoid long-term backlog.

4、 Precautions

Pay attention to batch and shelf life: There may be slight differences between different batches of paper, so it is important to distinguish them when using them. Meanwhile, attention should be paid to the shelf life of paper and avoid using expired paper.

Avoid contact with chemical substances: BOPP colored synthetic paper should avoid direct contact with strong acids, strong bases, and other chemical substances to prevent chemical reactions from causing paper deterioration.

Regular inspection: Regularly inspect the stored BOPP colored synthetic paper to promptly identify and address potential issues such as moisture, contamination, etc.

In summary, when storing BOPP colored synthetic paper, attention should be paid to the storage environment, storage conditions, storage methods, and multiple precautions. Only by doing these can we ensure that the quality and performance of the paper are not compromised during storage.
