This 43-485 deep skirt polypropylene (P/P) flip top smooth skirted closure has five holes each 0.200 inches in diameter. It includes a printed .008" C1S FS 3-25 perforated liner.
The liner is a one piece heat induction foil innerseal that provides an aggressive bond with clean peel removal from PET and PVC containers. It is printed 'Sealed for Freshness' in black. The perforations allow venting when required for the product being packaged, including food products. This liner does provide the consumer an indication of tampering (tamper evidency).
