PP 38-400 ribbed skirt lid with unprinted PS liner

Description: The PP 38-400 ribbed skirt lid comes with a unprinted pressure sensitive (PS) liner. Pressure sensitive liners are made from foamed polystyrene. When the cap (with liner installed) is affixed to the bottle, the liner adheres to the bottle’s landing/orifice. Before product can be dispensed, the lid must be removed, and the PS liner peeled off and discarded. This lid is made of polypropylene (PP), which means it has a high heat tolerance level and an excellent resistance to fatigue. 38-400 ribbed skirt lid fits a container with a 38-400 neck finish. The first number refers to the diameter of the container’s opening (in mm). The second number refers to the thread/style/depth of the closure’s skirt.
