Automatic Glass Jar Metal Twist Capper
The Automatic Glass Jar Metal Twist Capper with Vacuum Function is designed for continuous sealing of glass jars using metal twist-off caps under controlled vacuum conditions. It is typically installed in food processing plants, packaging factories, and export-oriented production facilities. The machine supports stable torque application and controlled vacuum sealing, helping maintain product quality during storage and transport. With an operating rate of around 35–40 bottles per minute and compatibility with a wide range of jar sizes, it fits well within industrial packaging operations across the UAE, GCC, and wider MEA region.
In UAE-based processing facilities in Dubai and Sharjah, the machine is commonly integrated downstream of filling lines and upstream of labelling or inspection stations. Its inline configuration allows smooth synchronization with conveyors and accumulation tables. The capper handles glass jars with heights from approximately 75 to 210 mm and supports adjustable capping torque in the 5–25 kg·cm range.
The machine operates using compressed air and an integrated vacuum system, ensuring consistent sealing even during extended production runs. Its rigid frame, stable conveyor alignment, and controlled head movement help reduce jar breakage and misalignment. These characteristics make it suitable for food

Frequently Asked Questions
This machine is commonly used in food processing plants, export packaging units, and central warehouses handling glass jars. Facilities in Dubai and Sharjah often use it for sauces, preserves, and spreads where vacuum sealing is required to maintain shelf stability during storage and regional distribution across the GCC and MEA.
The integrated vacuum system removes excess air from the jar headspace before capping. This reduces oxidation and pressure variation, which is critical when products are transported across the UAE and neighboring regions. It helps maintain seal integrity and minimizes leakage risks during temperature fluctuations in logistics chains.
Under stable conditions, operators can maintain an output of approximately 35–40 jars per minute. Actual performance depends on jar dimensions, cap type, and upstream filling consistency. In UAE production lines, this rate is typically sustainable across multi-hour shifts with standard preventive maintenance.
The capper is installed inline after the filling station and before labeling or inspection modules. Conveyor height and guide rails are adjustable, allowing alignment with common packaging layouts used in UAE factories. This setup supports uninterrupted product flow without manual intervention.
Regular checks include inspecting vacuum seals, cleaning air lines, and verifying torque settings. Operators usually perform daily surface cleaning and weekly inspection of pneumatic and vacuum components. This approach supports consistent sealing performance in high-throughput UAE industrial environments.
