Here is your answer...
Polyethylene terephthalate polyester(PETP) is a hard, stiff, strong, dimensionally stable material that absorbs very little water. It has good gas barrier properties and good chemical resistance except to alkalis (which hydrolyse it). Its crystallinity varies from amorphous to fairly high crystalline.


HOPE THIS HELPS YOU.
