Bags are filled with nitrogen, either pure or mixed with carbon dioxide, not so much to keep them inflated (that could be done with air), but to displace the oxygen, which would cause the oils to go rancid.
Carbon dioxide is also used sometimes,

∙ 12y agoNitrogen[N] is put in Crisps bags to keep them fresh. It is Oxygen which spoils the crips by oxidising them and making any fats or oils go rancid and water vapour in air makes them go soggy. So oxygen and water vapour which is about 20% of the air is removed and the remaining 80% is mostly Nitrogen, which does not react with the crisps.

How do you keep apple crisp crisp?
there are several important factors in keeping apple crisps, or infact many other crisps, crispy. If making them yourselves ensure the oven is at a high enough temperature, if cooked to slowly or not enough the crisp will -unlike it should- fail to crisp. This is due to the mafipulation process of high molecular re-construction weight distribution not being fully allowed to develop. You may fall in the trap of not wanting the burn the vagetable or fruit crisps, however, this should not be a problem. The moisture in the crisps, and in the oil needed to cook with them will ensure they stay un blackened and uneffected in taste by the extreme heat. If buying apple crisps which are not crispy, or loose there crisp after a while, ensure you are keeping them in a cool, dry place, and or ensure they are not dormont (too hot or too cold can cause the bacteria placement within any food to become "dormont" this is why frozen or cooked food will last longer).
