I'm shipping from New Orleans to Grand Island, Nebraska. The temperatures are in the upper 90s. I'm shipping overnight--so I'm assuming somewhere this involves an airplane.
I can't find sheets of Styrofoam. Anywhere. And I can't wait a week to have them delivered. I've tried Fedex and my local post office. They have an abundance of packing peanuts and bubble wrap but no sheets of Styrofoam.
I have some fancy "foam" stuff that Dell sent me when they sent my laptop. I have no idea if it keeps heat/cold in or out, but it cushions great. I also have a plastic container and lots of packing peanuts.
The set-up I have so far is sturdy box, foam, plastic box, packing peanuts, fish in triple wrapped bag.
Will this be enough to keep the heat out? I really don't know, but I need advice. The only thing I can think is maybe to put tin foil behind the foam as a further insulator.
Because of the temperatures I won't be adding a heat pack.
