Plan freezer space and safe storage duration for batch cooked meals.
Rigid containers waste around a quarter of nominal freezer volume through gaps, so usable capacity is well below the rating. Storage durations reflect quality loss rather than safety, since food held below minus 18 Celsius remains safe indefinitely. Overfilling a freezer slows freezing, and slow freezing forms larger ice crystals that damage texture, so leaving airflow space genuinely affects the result.
