Closures
We supply a diverse line of caps, closures, and lids to fit your vials, jars, packers, bottles, canisters, and containers. Choose from continuous-thread (CT), child-resistant (CR), hinged-dispensing, tamper-evident, or snap-top. Our closures come with various liner options, including foam, pressure sensitive, linerless, and heat induction, as required.
Continuous-Thread (CT) Closures
Continuous-Thread (CT) closures are designed to work with glass and plastic containers where the threads are wrapped around the neck of the container continuously. This is the most common style of closure. Neck finishes are identified by two numbers separated by a hyphen (i.e, 38-400) The first number is always in mm and refers to the diameter of the outside threads. The second number refers to the thread style (i.e., 400, 410, 415, etc.) and relates to the number of thread turns (e.g., 1, 1.5, 2, etc.). The closure finish chosen must match the neck finish of the container to ensure an optimal fit.
Features and Options:
- Sizes: 13-415 to 120-400, covering the most common diameters

Child-Resistant (CR) Closures
Child-Resistant closures are designed to require two motions (push-and-turn or squeeze-and-turn) to remove them from a container, making it challenging for a child to access the contents. They are mandated by law to protect children from exposure to potentially harmful products sold in the Rx and OTC pharmaceuticals, nutraceuticals, and cannabis industries. They are also frequently used as a safety precaution in the packaging of cosmetics, personal care products, and household chemicals. All of our CR closures are of the push-and-turn type.
