Introduction
Screw Cap Fitments serve as the primary closing mechanism for Bag-in-Box bags, providing a sealed port for filling and transport. Suzhou Jingle Packaging offers caps in various diameters (e.g., 1-inch, 2-inch) designed for automated or manual application. These fitments are utilized when the final user either transfers the liquid to another container or connects the bag to a specialized dispensing system, rather than using a tap directly.
The robust thread design ensures a leak-proof seal, critical for maintaining the product environment during logistics.
