Granule Weigh Fill Seal Production Line For Preformed Plastic Bags

The Granule Weigh Fill Seal Production Line is an automated packaging line used for filling granular products into preformed plastic bags. It supports controlled weighing, accurate filling, and reliable sealing in compact industrial layouts. The system is suitable for warehouses, food processing plants, and regional distribution centers. Typical installations support flexible bag formats and consistent output levels required in Omani packaging operations.



This production line combines bag handling, weighing, filling, and sealing into a single automated workflow. Pre-made bags are picked from the magazine, opened using vacuum assistance, filled with measured granules, and sealed before discharge. The process reduces manual labor while maintaining repeatable pack quality.

In Oman, including industrial areas around Muscat and Sohar, the line is used for packing dates, dried foods, grains, nuts, and industrial granules. The system typically supports filling capacities from a few grams up to several kilograms, with output speeds aligned to medium-scale production needs. Packing rates usually range from 20 to 40 bags per minute depending on product flow and pouch size.

The equipment uses stainless steel contact surfaces for hygiene and corrosion resistance. Pneumatic systems and vacuum generators ensure stable operation even with lightweight or flexible bags. PLC-controlled logic simplifies operation, making the line suitable for facilities with limited manpower and variable product mixes.

Frequently Asked Questions


Yes. The line is well suited for medium-scale factories and regional packing units in Oman. Facilities in Muscat and Sohar use it to balance automation with manageable footprint requirements, especially where flexible production volumes are needed.

Common applications include dates, dried fruits, grains, nuts, animal feed components, and industrial granules. Omani processors value the system for its ability to handle different granular materials without extensive mechanical changes.

The system uses stainless steel product-contact parts and sealed pneumatic components, making it suitable for coastal environments such as Sohar and Salalah. Regular cleaning and air filtration help maintain reliability where humidity and fine dust are present.

Operators with basic industrial training can manage the system after initial setup. The HMI provides clear status indicators and alarms, allowing Omani facilities with smaller technical teams to run the line efficiently without constant supervision.

Product changeovers mainly involve adjusting weigher settings and bag guides. In Nizwa and Muscat packing units, operators typically switch between SKUs within a short downtime window, provided bag dimensions remain within machine limits.

Daily cleaning of product zones, periodic inspection of sealing jaws, and routine checks of vacuum and pneumatic systems are recommended. These practices help Omani facilities maintain consistent sealing quality and avoid unplanned downtime.
