This 20-410 white polypropylene plastic (P/P) continuous thread closure has a fine ribbed skirt smooth top. It includes a F-217 foam liner. The F-217 foam liner is chemical and odor resistant and provides a low moisture transmission rate.
Note that a foam liner does not provide the consumer any indication of tampering (tamper evidency).
Match this closure to a jar with the same 20-410 neck finish to give your package an upscale look with added visual appeal.
