Physics, Astronomy & Cosmology / Why did the plastic film on my iPod lift up on during an aeroplane flight?

Kate Broughton asked the Naked Scientists:
Hi Chris
Great show everyone, keep up the good work.
Question
Recently whilst on a flight to Lesvos, Greece, I was listening to the latest Naked Scientist podcast on my ipod with the iplayer on the table in front of me.
I saw that the thin plastic removable protective cover on the front screen was slowly peeling off. I pressed it back into place but it started again and continued to lift itself from the edges inwards.
I wondered what was happening to the plastic to produce this effect. At first I thought that the plastic cover might be changing size in reaction to the cabin pressure in some way but if it was just that then after a time should not the cover stop changing size and stick back?
The process repeated continuously for the whole of the flight and the same thing happened on the return flight. Can you please explain what was happening?
Thank you
