Granule Weigh Fill Seal Production Line For Preformed Plastic Bags

The Granule Weigh Fill Seal Production Line is a fully integrated packaging solution for filling and sealing pre-made plastic bags with granular materials. It is widely used in large factories and logistics hubs handling dry food and industrial granules. The system supports precise weight control and repeatable sealing while operating at stable cycle rates. Typical installations support medium to high output requirements and are suited for industrial environments across Saudi Arabia.



Designed for high-duty packaging lines, this production system automates the entire bagging cycle—from bag pickup through final sealing. Granular products are weighed using dedicated weighers and discharged into open pouches held securely by mechanical grippers. The process minimizes spillage and maintains consistent fill accuracy across long production runs.

In Saudi facilities such as those in Riyadh and Jeddah, the line is commonly deployed for dates, nuts, sugar products, pet food, and chemical granules. Filling ranges typically span from 5 g to 4,000 g, while output capacity varies between 10 and 45 bags per minute depending on product density and bag format. Servo or frequency-controlled drives support smooth indexing and synchronized movements.

The system is engineered for round-the-clock factory operation, using robust pneumatic components and vacuum generators to manage bag opening reliability. Centralized PLC control enables alarm handling, reject logic, and quick adjustments, supporting production continuity in high-throughput Saudi manufacturing environments.

Frequently Asked Questions


The line is widely used in Saudi Arabia for dates processing, nut packing, dry food manufacturing, pet food plants, and chemical granule packaging. Large factories in Riyadh and Jeddah favor this system for its ability to maintain consistent output under high daily production volumes.

The equipment supports stable operation at controlled speeds using servo or frequency-driven indexing. In Saudi factories, operators often balance speed and accuracy, running between 20 and 40 bags per minute to ensure consistent weights while maintaining long production cycles.

The line is designed for preformed plastic bags within defined width and length ranges. Facilities in Dammam and Jubail commonly run multiple pouch sizes on the same machine, with changeovers completed through guided mechanical and HMI adjustments rather than complex retooling.

The system uses guarded moving parts, emergency stop circuits, and controlled pneumatic motion. In large Saudi plants, these safety measures help operators work safely during cleaning, bag replenishment, and inspection without disrupting adjacent production lines.

Accuracy depends on the selected weighing system and product characteristics. In practice, Saudi operators achieve stable weight control within acceptable tolerances for retail and bulk packaging by calibrating weighers regularly and maintaining consistent product flow conditions.

Once configured, the system performs bag pickup, filling, and sealing automatically. Alarm logic alerts staff only when intervention is required. This setup is commonly used in Saudi facilities aiming to reduce manual handling while maintaining controlled production output.
