PEN cap liner
A cap lining material that includes polyethylene naphthalate (PEN) is believed to be the first cap liner to use Kaladex(TM) film from ICI Polyester. The liner is available from Tri-Seal (Blauvelt, NY) and is suitable for PET bottles and PEN polymer bottles.
The cap liner was developed for hot-fill food beer and beverage packaging health care products and pharmaceutical applications requiring barrier properties beyond those of PET.
