The best temperature and humidity control method for storing cards
When storing high-value cards or memorable cards for long periods of time, one of the most important things to keep in mind is temperature and humidity control. Daily environmental management is essential to maintain the cards' beauty and protect their value. In this article, we will introduce the optimal temperature and humidity guidelines and specific management methods from a manufacturer's perspective.
Optimal temperature and humidity
Card materials (paper, ink, holographic processing, etc.) are sensitive to changes in temperature and humidity. The generally recommended storage environment is as follows:
- Temperature: 18~25℃
- Humidity: 40-60%
If the temperature is outside this range, the risk of warping, ink bleeding, mold, and deterioration increases. In particular, in Japan, where summers are hot and humid and winters are very dry, seasonal measures are necessary.
Specific temperature and humidity control methods
- Install a thermo-hygrometer: Installing one not only indoors but also inside the storage case will allow you to get an accurate grasp of the environment.
- Use dehumidifiers and desiccants: Stabilize the humidity inside cases and storage boxes. It is important to replace them regularly.
- Use a humidifier and dehumidifier together: Use them according to the season to prevent sudden changes in humidity.
- Air circulation inside the case: To avoid sealing it too tightly, make sure to provide small vents or ventilate it regularly.
Storage environments to avoid
- Places exposed to direct sunlight (UV rays can cause discoloration and deterioration)
- Locations directly exposed to air conditioning (sudden changes in temperature and humidity)
- Places where extreme temperature and humidity changes are likely to occur, such as attics and closets
- Floor-standing (easily affected by moisture)
Use of auxiliary tools
For safer storage, humidity-proof cabinets and cases with UV protection are effective. Humidity-proof cabinets can maintain a stable temperature and humidity, while also protecting against UV rays. Our "Card Armor" UV-blocking products and magnetic loaders are popular with many collectors for high-value cards and long-term storage.
summary
The basics of card storage are "appropriate temperature and humidity management" and "avoiding direct sunlight and sudden changes in the environment." The key to protecting the value of your cards is to maintain a consistent level of daily care. To protect your precious collection, take a look at your storage environment now.
