Black PP plastic 28-400 ribbed skirt hinged flip top snap dispensing lid

with unprinted pressure sensitive (PS) liner (0.250 inch orifice)

The L2303BKP1 is a black PP plastic 28-400 ribbed skirt hinged flip top snap dispensing lid with unprinted pressure sensitive (PS) liner and 0.250 inch orifice. Flip top snap dispensing lids have a hinge that snaps the lid into place. Because it is made of polypropylene (PP), this hinged lid can be opened and closed thousands of times before breaking. The orifice opening is 0.25". This lid comes with a pressure sensitive (PS) liner. Pressure sensitive liners are made from foamed polystyrene. When the lid (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. This closure fits a container with a 28-400 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.
