This article provides a detailed introduction to the features, technical parameters, and application advantages of a fully automatic spout pouch filling and capping machine. Then you can better understand this highly efficient packaging equipment that integrates automatic bag feeding, filling, cap sorting, and capping.

A spout pouch filling and capping machine is a fully automatic filling device specifically designed for spout pouch packaging. It integrates automatic bag feeding, automatic filling, automatic cap sorting, and automatic capping, achieving fully automated production from empty bags to finished products.
Project | Description |
Equipment name | Fully Automatic Spout Pouch Filling and Capping Machine |
Core functions | Automatic bag feeding, quantitative filling, automatic cap sorting, and automatic capping |
Applicable packaging | Spout pouches |
Applicable materials | Food sauce, food liquid, cosmetic cream, lotion, chemical liquids, etc |
Automation level | Automatic type; basically one person can operate. |
Applicable Scenarios | Description |
Small to large scale factories | Different models in supply to meet different speed demands |
Mass production | Stable large-volume orders |
Now that we understand the concept of the equipment, let's take a closer look at its composition and workflow.
Combination Part | Remark |
Bag feeding system | Bag hanging rail |
Cap feeding system | Cap lifting conveyor(Usually for the 4 head to 12 head filling machines; for 1 head or 2 head ones, no need) |
Cap sorting system | Vibration cap sorter |
Dosing pump | Piston/rotor pump/gear pump,etc |
Filling system | Feeding pump, filling nozzle |
Cap screwing system | Mechanical hand, servo motor control |
Bag out system | Automatic sending out the bags |
Manually insert bags to the bag hanging rail → Automatic bag feeding → Product filling → Automatic cap feeding → Automatic cap screwing → Automatic bag out
To clearly show you the machine combinations and the work flow, following are the videos of our SLXF-1 model(the first one) and SLXF-4 model(the second one) spout pouch bag filling capping machine:
To make you know more about the machine functions, following are the introduction of the main functional parts:
Function | Description | Advantages |
Bag hanging system | Different models can load dozens to hundreds of bags at a time | Reduce frequent manual bag loading |
Automatic bag feeding | After the bag enters the bag hanging rail, the device will activate the automatic bag feeding mode. | Success rate ≥ 99.5% |
1) Three Mainstream Filling Methods Available
Filling Method | Applicable Materials | Features |
Piston pump | Suitable for low to medium viscosity materials | Good cost performance |
Rotary pump | Covers low, medium, and high viscosity materials | Suitable for high viscosity, fast filling speed |
Gear pump | Suitable for low to medium viscosity materials | High cost performance, relatively fast speed |
2) Filling System Features
Feature | Description |
Servo drive | Precisely adjustable filling volume with high repeatability |
Anti-drip design | Filling nozzle with back suction function to prevent dripping |
Submersible filling | Filling nozzle extends into the bag to avoid splashing |
Quick adjustment | One-touch switching of filling volume via touchscreen |
3) Automatic Cap Sorting System
Function | Description | Advantages |
Vibration cap sorter | Automatically arranges cap orientation | Applicable to various cap sizes |
Lid slide | Smoothly conveys caps to the picking position | No cap jamming |
4) Automatic Capping System
Functions | Description | Advantages |
Servo capping | Precise torque control | Reliable sealing, no damage to caps |
Adjustable torque | Adjustable according to cap size | Applicable to different cap types |
Model | SLXF-1 | SLXF-2 | SLXF-4 |
Overall size | 890*870*800mm in L*W*H | 1400*1200*1700mm in L*W*H | 2800*2100*2300mm in L*W*H |
Motor power | 2KW | 3KW | 6KW |
Filling volume | 30-2000ml | 30-2000ml | 30-2000ml |
Filling speed | 5-35BPM | 10-60BPM | 40-80BPM |
Control method | PLC touch screen | PLC touch screen | PLC touch screen |
Main material | SS304 | SS304 | SS304 |
(Remark: we have the 12 heads for the highest speed 200-300BPM. For the limited space, we only show three models.)
As described above, the spout pouch filling capping machine integrates bag loading, filling, capping, and screw-capping functions into one machine. This provides customers with a more efficient filling solution. Furthermore, we offer different models to suit varying production line speed requirements.
