Humidity and paper storage in Korea

Sealed envelopes feel permanent until a humid July reminds you that paper breathes. In Korea, monsoon stretch and late-summer heat can stress ink, adhesives, and the cardboard sleeves people trust a little too much.

What humidity changes

Laser toner can remain readable while paper cockles and edges feather. Labels peel. Metal cabinets in non-conditioned corridors collect condensation when doors open frequently. None of this means panic; it means your re-check calendar should acknowledge the season.

Adjust the interval, not the standards

Many SystemStorage Grid learners keep a baseline 90-day verification cycle, then shorten to 30–45 days from June through September for packs stored outside tightly controlled rooms. The comparison steps stay the same — only the cadence changes.

Simple environmental habits

• Keep silica packs labeled with refresh dates if you use them; unmarked desiccant becomes superstition.
• Avoid floor-level storage in older buildings where flooding risk is non-zero.
• When reprinting after moisture damage, destroy the compromised page under your dual-control rule and log the replacement.
