The L210B is a ribbed black lid made from polypropylene (PP). The lid is designed to fit containers with a 48-400 neck finish. The lid also includes a printed pressure sensitive liner (PS liner) which will create a seal when applied. This makes the lid ideal for honey containers as well as smaller cosmetic and other applications.
