Will instant naeng myeon soup packets go bad if unrefrigerated?

[TonyC]

The reason I ask: I'm sending a case of it to Middle America, where the Korean-food sun apparently don't shine.

Shipping these frozen, via dry ice, will essentially negate any savings meant for my pal (hi @foodrush!)

If I send them just overnight, and go to the PO right after taking the packets out of the freezer, I'm thinking they may still be slightly chilled by the time it gets to the Rust Belt.

The main ingredients shown on the packets are: beef stock, water, pear juice, etc.

Any thoughts?

i would send in the winter months if possible. my parents used to send me japanesen food care packages to wa. state from calif. during the winter, to ensure natural cold refridgeration.
hope this helps.
