At SKS we understand there are many factors to consider when selecting a closure for your container, such as how the product should be dispensed, if the packaging requires extra protection, and the overall style you'd like to achieve. To meet your packaging needs we provide a vast inventory of closures in both the screw thread or continuous thread styles as well as lug caps to pair with various containers based on neck finish. Whatever your packaging needs, we have the perfect closure for you, whether it's a dispensing, non-dispensing, metal, or plastic cap. We offer both unlined and lined caps including PE, F217, pressure-sensitive, plastisol, or induction liners. Choose from shrink bands and tamper evident closures to give customers peace of mind. To make finding the right closure easier, we offer Cap Code measurements to match closures and containers.
