When storing BOPP synthetic label paper, the following aspects need to be paid attention to to ensure that the quality and performance of the label paper is not damaged:
First,Environmental conditions
1.Temperature and humidity:
The recommended storage temperature ranges from 21° to 25° and the relative humidity ranges from 45% to 55%. Such temperature and humidity conditions help to maintain label stability and prevent deformation, adhesion, and glue failure caused by temperature and humidity changes.
Be careful to avoid a low temperature that will cause the label to be less viscous, because low temperatures will reduce the bonding speed, so that the label may have peeled off the surface before use.
2.Illumination:
Prevent direct sunlight to prevent the label from fading, aging, or glue failure.
Second,Packaging and stacking
1.Packing and sealing:
Label paper should have an outer package. It is recommended to use a plastic film to seal the package. After each use, the label should be sealed and packed again to prevent moisture intrusion and dust pollution.
For rolled label paper, it should be stacked upright, and flat label paper should be stored flat to avoid curling or deformation.
2.Stacking height and stability:
The stacking height should be properly designed based on warehouse conditions and label weight to avoid deformation or damage to labels at the bottom caused by excessive stacking.
When stacking, the bottom should be padded with moisture-proof materials such as wooden boards to avoid direct contact with the ground and wall to reduce moisture intrusion.
Third, electrostatic protection
BOPP materials are liable to generate static electricity. Therefore, ESD preventive measures must be taken during storage, such as increasing the ambient humidity, packing or laying ESD materials, and grounding the BOPP materials to prevent accidents such as fire or explosion caused by static electricity.
Fourth,Safety and fire protection
Storage warehouses should be equipped with appropriate fire equipment and facilities, such as fire extinguishers, fire hydrants, etc., and regular fire inspection and maintenance to cope with possible fire risks.
Fifth, first in, first out principle
Follow the principle of "first in, first out" to use the stock label paper to ensure the freshness and performance of the label paper, and avoid the quality decline caused by long-term storage.
In summary, when storing BOPP synthetic labels, it is necessary to pay attention to environmental conditions, packaging and stacking, electrostatic protection, safety and fire protection, and the first-in-first-out principle to ensure that the label maintains good quality and performance during storage.
