I had just the best idea.
What if we take the camping cooling bag. The one with reflective foil inside. As a shopping bag. Just place the delicate meat, milk, butter, eggs, fish together with a frozen soda bottle.
I think this works for countries in Asia, Africa or where the climate is hot.
For Sweden I’m going to try this for hot half a chicken meals now in winter. Here I don’t need anything hot in the bag. Just the hot chicken.
A product Idea would be to create these kind of bags for take home pizza. Just let the customer buy the reusable pizza bag and place the the pizza in the regular paper container inside the Thermos Pizza Bag.
