Our 63-400 white polypropylene continuous thread closure has a ribbed skirt, a matte (stipple) top, a slightly raised ring around the outside of the top edge to facilitate stacking of bottles, and an induction seal liner. Polypropylene (PP) is a highly impermeable and tough material that is lightweight and durable thermoplastic.
The ISPP U10 Plain (unprinted) liner is a one piece foam backed heat induction foil inner seal that will, when applied correctly, provide a tamper indicating (tamper evident) welded seal to P/P containers. The transmission rates for oxygen gas and moisture vapor are essentially zero.
