After production, the warm patch is sealed while a brief oxidation reaction occurs, producing a small amount of steam. When the steam touches the cooler inner surface of the polybag, it condenses into visible water droplets.
Within 1–2 days, the droplets will be naturally absorbed by activated carbon, water-absorbing resin, and vermiculite inside the bag.
This is a purely physical phenomenon and does not affect product quality, heating performance, or normal use. Please rest assured.
