Hex shaped Poly Plugs for plastic packaging tubes are designed to prevent rolling off shelves making these ideal for many retail package applications at economical costs. When shelf room is not abundant and hanging is not an option, plugging a round tube with a flat-bottom Hex Poly Plug will increase your space. The flat surface supports the standing or stacking of the tubes. HDPE plastic tube plugs featuring the hexagonal shape top are stocked in black. Custom colors are available. Looking for another type of top or container, or want to see all of the additional options included with our containers?
