Cold packing beats moisture sheets every time

Pack your lunch completely cold before it goes in the insulated bag—that’s the only way to actually stop condensation, not just clean up after it.

Condensation happens when warm, moist air hits a cooler surface. If your food is still warm when you pack it, it gives off steam that condenses on the bag’s interior and drips right back onto your meal. That’s what makes things soggy.

Moisture-absorbing sheets (or even a paper towel in the bag) will soak up some of that water, but they’re fighting the symptom, not the cause. Cold food doesn’t release moisture, so there’s nothing to condense in the first place. That’s why cooling your food completely before packing—and adding an ice pack—works so much better.

A sheet is a band-aid; a cold pack is a cure.
