A technique that I wish American food makers would use: collapsible packaging.
My refrigerator contains milk jugs and takeout boxes that are 80% empty. Unfortunately, they eat up as much space as full containers. If they were collapsible, I’d have more room in the fridge.
Of course, I can move the almost-empty containers’ contents into small or collapsible containers. But as a red-blooded lazy American, I’d rather skip that step and buy food in boxes and bottles that are themselves collapsible.
These containers could even offer a marketing benefit. If I can collapse a food maker’s box instead of moving the food to a smaller box and throwing out the original, I’ll keep the maker’s box longer — and see the maker’s logo over and over.
