Cooking is my passion and milk cartons are layered and store the food adequately for long time. it is a lot easier to stack and less waste full .You should also try it as I consider this as a replacement for plastic boxes and bags
I love the idea and would implement it on potatoes. How you stack it standing up or lying down, especially when food include liquid like products and gravy?
Milk cartons I used is several layered and for liquid products when freezes doesn’t make a spill and can be stacked as you like
