70-400 Black Dome Plastic Cap with Foam Liner

This 70-400 black dome plastic cap adds a rounded, elevated finish that makes your jars stand out on the shelf. The domed top gives a softer, more premium silhouette than a flat cap, and the black finish pairs well with clear, amber, white, or frosted containers. Each cap has a polyethylene foam liner that compresses against the container rim when tightened. This creates a dependable, leak-resistant seal that keeps contents fresh and helps prevent spills during shipping and storage. Features Size: 70mm diameter with a 400 neck finish Style: Dome top for a distinctive, upscale look Liner: Foam liner for a secure, leak-resistant seal Color: Black Compatibility: Fits glass and plastic containers with a 70-400 neck finish Ideal For Creams, body butters, balms, salves, scrubs, gummies, herbs, spices, and other products packaged in 70-400 jars. A strong choice for cosmetics, skincare, food, cannabis, and home goods brands that want packaging with a little more presence. Tip: Always confirm your container’s neck finish before ordering, since a 70-400 cap will not properly fit 70-450 or other finishes. For oil-heavy or solvent-based products, test the liner with your formula first.
