HUIDA PACKING provides fully automatic 25–50kg heavy bag salt packaging and palletizing lines designed for salt manufacturers, food salt processors, industrial salt producers and bulk material suppliers.
The complete automatic packaging system integrates automatic weighing, bag filling, bag conveying, bag sewing and automatic palletizing, helping salt producers improve packaging efficiency, reduce manual labor and achieve a more consistent finished-bag output.
Designed for heavy-duty industrial applications, the system is suitable for packaging salt into 25kg, 30kg, 40kg and 50kg bags, with customized configurations available according to product characteristics, bag type and production capacity.
Salt is a free-flowing granular material that can generate dust during filling and handling. When packaging salt in heavy 25–50kg bags, a reliable packaging system needs to provide accurate weighing, stable filling and dependable bag closing.
HUIDA PACKING's heavy bag automatic salt packaging line is engineered to automate the complete packaging process.
Bulk Salt Feeding → Automatic Weighing → Bag Clamping → Bag Filling → Bag Release → Bag Conveying → Bag Sewing → Finished Bag Conveying → Automatic Palletizing
By integrating these processes into one production line, manufacturers can significantly reduce manual handling and improve overall production efficiency.
The automatic weighing system measures the required quantity of salt before filling each bag.
For heavy-bag applications, stable weighing is particularly important because even small weight deviations can result in significant material losses over thousands of bags.
HUIDA PACKING heavy bag packaging machines can achieve a weighing accuracy of approximately ±0.2%, depending on the product characteristics and selected configuration.
The system is designed specifically for heavy-duty bagging applications.
Typical packaging weights include:
25kg salt bags
30kg salt bags
40kg salt bags
50kg salt bags
The packaging system can be configured according to different bag dimensions and packaging materials, including woven polypropylene bags, kraft paper bags and composite bags.
For large-scale salt production, packaging speed is a critical factor.
HUIDA PACKING heavy bag packaging machines can reach a maximum packaging capacity of up to 1,200 bags per hour, depending on the target bag weight, salt characteristics, bag specifications and complete line configuration.
For example, a high-speed 25kg salt packaging line can provide a significantly higher hourly output than manual bagging operations.
The actual production speed should be confirmed according to the customer's product and production requirements.
After filling, the heavy salt bag is automatically transferred to the bag closing station.
For woven or similar open-mouth bags, the system can use an industrial bag sewing machine to securely close the filled bag.
Automatic bag closing provides:
Consistent sewing quality
Reliable bag sealing
Reduced manual operation
Better production continuity
Cleaner and more organized packaging operations
The sewing system can be integrated directly into the automatic conveying system.
Packaging is only one part of a modern salt production line.
After the bags are filled and sewn, finished 25–50kg bags still need to be stacked for storage and transportation.
HUIDA PACKING can integrate an automatic palletizing system after the bagging and sewing equipment.
The palletizing section can automatically:
Receive finished salt bags
Convey bags to the palletizing area
Adjust bag orientation
Arrange bags according to the programmed pallet pattern
Stack multiple layers
Build a stable pallet
Transfer completed pallets for wrapping or storage
Automatic palletizing eliminates much of the repetitive heavy lifting traditionally performed by workers.
This is especially valuable when handling 25kg and 50kg salt bags throughout long production shifts.
Manual weighing, filling, sewing and palletizing require multiple operators and involve repetitive heavy lifting.
An integrated automatic packaging line reduces these labor-intensive operations and allows operators to focus on machine supervision and production management.
Automatic weighing and filling help maintain a more consistent quantity in every bag.
Automated conveying and bag closing also help standardize the production process.
Instead of treating bag filling, sewing and palletizing as separate operations, the complete system connects them into a continuous automated process.
This can help salt manufacturers increase production efficiency and reduce bottlenecks between different production stages.
Automatic conveying and palletizing create a more organized finished-product area.
Palletized salt bags are easier to move using forklifts or pallet handling equipment, making warehouse management and transportation more efficient.
The HUIDA PACKING heavy bag salt packaging system can be customized for different types of salt and similar granular materials.
Potential applications include:
Table salt
Refined salt
Industrial salt
Vacuum salt
Sea salt
Granulated salt
Solar salt
Coarse salt
Other free-flowing granular materials
The final feeding and weighing configuration should be selected according to the salt's particle size, bulk density, moisture, flowability and dust characteristics.
A typical HUIDA PACKING automatic salt packaging and palletizing line can include:
Transfers bulk salt from the production or storage system to the weighing unit.
Precisely weighs the required amount of salt for each bag.
Automatically fills the weighed salt into the empty 25–50kg bag.
Transfers filled bags smoothly between different stations.
Closes the filled woven or open-mouth bag.
Helps organize the filled bags before palletizing.
Automatically arranges and stacks finished bags onto pallets.
Transfers completed pallets to the next stage.
Can be added when customers require automatic pallet stabilization and protection during transportation.
Different salt factories have different production requirements.
Therefore, HUIDA PACKING does not simply provide one standard configuration for every customer.
Our engineers can design the packaging line according to:
Salt type
Particle size
Bulk density
Moisture content
Dust characteristics
Bag material
Bag dimensions
Packaging weight
Required bags per hour
Factory layout
Pallet dimensions
Palletizing pattern
Available power supply
This allows the complete 25–50kg automatic salt packaging line to be adapted to the customer's actual production environment.
