I wouldn't pass them onto kids.
The only concern would be the oil going rancid. If it has you will know the minute a bag is opened as it will smell like paint thinner.
Most chip bags are flushed with nitrogen to displace the oxygen to prevent this. The film itself is an excellent oxygen barrier so oxygen migration into the bag is minimal. Now if the bag has pin holes the nitrogen would be replaced by oxygen increasing the rate of rancidity.
hmm, you may be on to something. the oil didn't smell but had a stronger aftertaste and lingered in the mouth for awhile. i think i will play it safe and just toss em
