Man of Honour
Aren't the first paragraph and the last line of the second paragraph contradictory? If the first is true (which I agree, it is) then surely cardboard is good for at least keeping air from escaping as easily vs empty space?Remember that a full freezer is an efficient freezer as there’s less air to cool after every time it’s opened.
Remove the boxes from any frozen foods supplied this way and put the contents in a freezer bag along with the cooking instructions section of the box. No point in wasting space and electricity keeping cardboard boxes frozen.
