CSD caps are designed specifically for carbonated soft drinks and other carbonated beverages, where maintaining a secure seal is essential for preventing leakage and preserving carbonation. The caps are manufactured through precision injection moulding. Plastic resin is heated until it reaches a molten state and is injected into a precision mould under controlled pressure. Once formed, the cap is cooled and removed from the mould. Features such as the internal thread, sealing area, and tamper-evident ring are incorporated into the mould design. Rifat Plastic's product information specifically describes its CSD caps as injection-moulded plastic closures used to seal carbonated soft-drink bottles. CSD caps are primarily used for: Carbonated soft drinks Soda Sparkling beverages Flavoured carbonated drinks Other PET-packaged carbonated products The objective is to provide a secure, consistent, and dependable closure compatible with high-volume beverage filling operations.
