Create a layer of block ice at the bottom of the cooler. Use block ice takes longer to melt that cubed ice. You can make your own block ice out of water jugs which are convenient, because as it melts, you have drinking water.
Pour cubed ice over the layer of block ice and fill in any open spaces. We are trying to reduce any opportunities for air.
Frozen fish, meats, etc. go on the ice. Fresh fruits and veggies will go in last.
Use a closed-cell foam mat, like a yoga mat, to create a barrier between the ice and frozen food and your other items to help keep them from freezing.
Keep your breakfast foods on one side, lunch in the middle, dinner on the other side. Then label the outside of the cooler and create a food map so you can minimize any time the cooler is open by knowing exactly where to find what you’re looking for.
