Superior barrier properties:
PEF’s oxygen barrier is 10 times better than PET
PEF’s carbon dioxide barrier is 6 to 10 times better than PET
PEF’s water barrier is twice as good as PET’s
More attractive thermal properties:
The Tg of PEF is 86°C compared to the Tg of PET of 74°C
The Tm of PEF is 235°C compared to the Tm of PET of 265°C
