Automatic Tubular FFS Bagging Machine Heavy Duty Form Fill and Seal Packaging System for Citric Acid Chemical Granules 25kg–50kg

HUIDA PACKING | Heavy-Duty Automatic FFS Bagging Machine | Up to 1800 Bags/Hour

HUIDA PACKING's Automatic Tubular FFS Bagging Machine is a heavy-duty form fill and seal packaging system designed for high-volume industrial packaging of citric acid, chemical granules, fertilizers, mineral products, plastic granules, feed materials and other free-flowing bulk solids.

The system automatically forms, fills and heat-seals bags from a continuous tubular PE film roll, eliminating the need for pre-made bags and significantly reducing manual packaging operations.

Designed for 25kg–50kg heavy bag applications, the high-speed configuration can achieve up to 1800 bags/hour, depending on product characteristics, bag size, film specifications and feeding/weighing configuration.

High-Speed FFS Packaging for Citric Acid

Citric acid is commonly supplied and transported in industrial quantities, making packaging speed, weighing accuracy, sealing quality and bag durability important factors for chemical manufacturers and exporters.

HUIDA PACKING's tubular FFS system provides a continuous packaging process in which the machine automatically creates the bag from a tubular PE film roll, fills the predetermined quantity of citric acid and heat-seals the finished bag.

This integrated process helps reduce manual bag handling while maintaining consistent package dimensions and sealing performance.

HUIDA PACKING has already developed FFS packaging solutions for 25kg citric acid applications, demonstrating the suitability of tubular FFS technology for this type of chemical material.

Why Use Tubular FFS for 25kg–50kg Chemical Granules?

1. Fully Automatic Bag Forming

Unlike traditional open-mouth bagging systems, the FFS machine produces bags directly from a continuous tubular film roll.

There is no need to manually supply empty bags one by one.

2. High-Speed Continuous Packaging

For high-output chemical production lines, packaging speed is critical.

The high-speed configuration is designed for production requirements of up to 1800 bags/hour, helping chemical plants increase packaging throughput and reduce bottlenecks between production and warehouse operations.

3. Heavy-Duty Bag Construction

The system is designed for heavy industrial bags ranging from 25kg to 50kg.

Heavy-duty PE film can provide strong mechanical protection during conveying, palletizing, transportation and storage.

4. Consistent Filling Weight

The weighing and filling system is engineered for continuous quantitative packaging.

The final weighing configuration can be selected according to the product's bulk density, particle size, flow characteristics and required accuracy.

5. Automatic Heat Sealing

After filling, the bag is automatically sealed by the FFS sealing system.

This produces a consistent top seal and reduces the risk of inconsistent manual sealing.

6. Reduced Labor Requirements

The automated process integrates:

Bag forming + weighing + filling + sealing + conveying

This can substantially reduce the number of operators required compared with conventional manual bagging processes.

Technical Specifications

Note: Actual production capacity depends on product characteristics, target weight, film specifications, bag dimensions, feeding system and line configuration. The 1800 bags/hour figure represents the maximum capacity of the applicable high-speed configuration and should be confirmed based on the customer's material and packaging requirements.

Heavy-Duty FFS System for Chemical Plants

For chemical manufacturers, the packaging machine must operate reliably for long production cycles.

HUIDA PACKING's heavy-duty FFS solution is designed around industrial requirements including:

Continuous Production

Designed for high-volume packaging environments and long operating cycles.

Stable Film Handling

The tubular film feeding system continuously unwinds and positions the film before bag forming.

Automatic Bag Length Control

Bag length can be controlled according to the packaging specification, with automatic detection and adjustment options.

Easy Maintenance

The machine structure provides access to key operating and maintenance components, helping reduce maintenance downtime.

Dust Management Options

For dusty chemical materials, dust extraction and air evacuation systems can be configured according to the characteristics of the product.

Flexible Integration

The FFS bagger can be integrated with upstream material handling and downstream conveying, palletizing and wrapping equipment.

Complete Automatic Packaging Line

For large chemical production plants, HUIDA PACKING can provide a complete automated packaging solution rather than only the bagging machine.

A typical line can include:

Raw Material Feeding System

→

Buffer Hopper

→

Automatic Weighing System

→

Tubular FFS Bagging Machine

→

Finished Bag Conveyor

→

Check Weigher

→

Metal Detector

→

Automatic Reject System

→

Robotic Palletizer

→

Automatic Stretch Wrapper

→

Finished Pallet Conveyor

This configuration can create a continuous packaging workflow from bulk material feeding to palletized finished products.

Benefits for Chemical Manufacturers

Higher Packaging Productivity

High-speed automatic packaging can help increase production throughput and reduce packaging bottlenecks.

Lower Packaging Labor Cost

Automatic bag forming, filling and sealing reduces manual bag handling and operator dependency.

Flexible 25kg–50kg Packaging

The system can be engineered around different industrial bag weights and dimensions.

Better Packaging Consistency

Automatic weighing, film forming and heat sealing help maintain consistent bag quality.
