This 110-400 polypropylene CT closure has a ribbed skirt and a matte (stipple) top. It includes a pressure sensitive polystyrene foam liner, which is the equivalent of a PS22 liner. The liner is plain (unprinted). A pressure sensitive liner is designed to be an innerseal for dry products such as pharmaceuticals, nutraceuticals and food. It will provide a tight innerseal on both glass and plastic bottles.
