[NAFEX] Apple Storage?

My cold room has a high and low air vent, so there is regular fresh air
exchange. Little risk from leaking CO2 there.
I would hope the CO2 could be trapped and sealed in whether a person used
large plastic bags, or plastic boxes with air tight lids.
I would only open one bushel of apples at a time, leaving others
undisturbed with CO2 pooled inside.
Just a thought.
