Are Pokémon cards sealed with dry nitrogen or purged in any way? Unverified

Sealing Methods for Pokémon Cards

Pokémon cards are typically sealed in packaging that is designed to protect them from environmental factors such as moisture, dust, and physical damage. However, the specific methods used for sealing, such as whether dry nitrogen is employed or if any purging occurs, are not publicly detailed by the manufacturers.

Generally, the focus is on using materials that provide a barrier against moisture and air, which can degrade the cards over time. This is crucial for maintaining the quality and longevity of the cards, especially for collectors and investors.

While some collectors may use additional methods, such as storing cards in airtight containers or using silica gel packs to absorb moisture, these practices are not standard in the manufacturing process of Pokémon cards.
