The white polypropylene dome caps are available in a variety of cap sizes and fit many containers. The 26/400 dome caps are unlined, while the rest of the cap options listed come with a PE liner. The PE liner has excellent chemical resistance and a low moisture transmission rate, along with good taste and odor resistance, making these caps great for packaging a variety of products. When selecting compatible plastic caps for your container of choice be sure to match the cap code of the dome caps with the cap code of your container.
