Screw caps, also known as screw-on caps or threaded caps, are a common type of closure used in packaging to seal containers. They consist of a cap with internal threads and a corresponding threaded neck or opening on the container. By twisting the cap onto the container, the threads engage, creating a secure and tight seal.
Here are some key features and information about screw caps:
Design: Screw caps typically have a circular shape and are made of materials like plastic, metal, or a combination of both. The cap's interior surface has threads that match the threads on the container neck. This threaded design allows for easy opening and closing of the container by twisting the cap.
Thread Types: There are different thread types used for screw caps, including continuous thread and child-resistant (CRC) thread. Continuous thread caps have threads that extend all the way around the inner surface of the cap, providing a standard seal. CRC caps have special mechanisms that require a specific combination of push-down and twist actions to open, making them child-resistant.
Seal: When the screw cap is fully tightened onto the container, the threads create a tight seal that helps prevent leakage, contamination, and oxidation. Some screw caps also include additional sealing elements like liners or gaskets, which provide added protection against air or liquid ingress.
Compatibility: Screw caps are compatible with a wide range of container materials, including plastic, glass, and metal. The threaded neck on the container and the cap should have matching thread sizes and types for a proper fit and seal.
Applications: Screw caps are widely used in various industries, such as food and beverage, pharmaceuticals, personal care products, chemicals, and more. They are suitable for packaging a wide range of products, including liquids, powders, creams, and solid goods.
Versatility: Screw caps can come in different sizes, colors, and styles, allowing for customization and branding options. They can be tamper-evident, equipped with induction seals, or have features like flip-top or dispensing closures for added convenience.
Overall, screw caps are popular for their reliability, ease of use, and effective sealing properties. They offer a secure closure for containers, protecting the contents and extending their shelf life.

Screw caps are commonly made from a variety of materials, depending on the specific application and requirements. Here are some materials frequently used for manufacturing screw caps:
Plastic: Plastic screw caps are widely used due to their versatility, cost-effectiveness, and lightweight nature. Common plastics used include polyethylene (PE), polypropylene (PP), high-density polyethylene (HDPE), and polyethylene terephthalate (PET). Plastic caps can be molded into various shapes, sizes, and colors, offering flexibility for customization.
Metal: Metal screw caps provide durability, a premium look, and enhanced protection for certain products. Aluminum and tinplate are popular choices for metal caps. Aluminum caps are lightweight, corrosion-resistant, and commonly used in the beverage and pharmaceutical industries. Tinplate caps, made of steel coated with a layer of tin, offer excellent barrier properties and are often used in the food industry.
Combination of Plastic and Metal: Some screw caps combine plastic and metal components to leverage the benefits of both materials. For example, the cap body may be made of plastic while the inner seal or liner is made of aluminum or other metals. This combination can provide a secure seal while maintaining the ease of use and customization options of plastic caps.
Composite Materials: Composite screw caps utilize a combination of materials, such as plastic and pulp, to offer a sustainable and eco-friendly option. These caps are often used in industries where sustainability is a priority, such as organic food or natural cosmetics.
The choice of material for screw caps depends on factors such as product compatibility, required barrier properties, aesthetics, cost considerations, and sustainability goals. Manufacturers select the appropriate material based on the specific needs of the product and the industry it serves.
