What are the storage requirements for BOPP colored synthetic paper?

The storage conditions for BOPP (biaxially oriented polypropylene) colored synthetic paper need to meet the following requirements to ensure the stability of its quality and performance:

1、 Environmental humidity

Keep dry: BOPP colored synthetic paper should be stored in an environment with low relative humidity. It is generally recommended to keep the relative humidity below 50% to prevent the paper from deforming or producing ruffles due to moisture absorption. During periods of high humidity such as the rainy season in the south, special attention should be paid and dehumidification measures should be taken.

2、 Environmental temperature

Suitable temperature: The temperature of the storage environment should be moderate to avoid adverse effects on the paper caused by excessively high or low temperatures. It is generally recommended to store at a temperature below 30 ℃ to prevent paper from aging or deforming due to heat. In high temperature environments, measures should be taken to cool down, such as using air conditioning or fans.

3、 Lighting conditions

Avoid direct sunlight: Prolonged exposure to sunlight may cause BOPP colored synthetic paper to fade or age. Therefore, direct exposure of paper to sunlight should be avoided, and shading cloth or curtains can be chosen for protection.

4、 Dust and pollution prevention

Keep clean: The storage environment should be kept clean to prevent dust and pollutants from adhering to the paper. You can use dust covers or plastic bags to wrap the paper to reduce dust pollution. At the same time, paper should be avoided from being placed in environments that may be contaminated, such as near chemicals.

5、 Stacking and protection

Flat stacking: BOPP colored synthetic paper should be stacked neatly and evenly, avoiding "one fold and three stacks" to prevent deformation or damage of the paper due to uneven stress.

Avoid placing heavy objects directly on paper to prevent deformation or damage. Paper can be lifted up using shelves or trays to reduce stress.

6、 Other precautions

Pay attention to batch and shelf life: There may be slight differences between different batches of BOPP colored synthetic paper, which should be distinguished during storage. Meanwhile, attention should be paid to the shelf life of paper and avoid using expired paper.

Follow manufacturer's guidance: When using and storing BOPP colored synthetic paper, follow the manufacturer's guidance and recommendations to ensure normal use and extend the lifespan of the paper.

In summary, the storage conditions for BOPP color synthetic paper need to meet the requirements of environmental humidity, environmental temperature, lighting conditions, dust and pollution prevention, stacking and protection, and other precautions. By following these storage conditions, the stability of the quality and performance of BOPP colored synthetic paper can be ensured, and its service life can be extended.
