1.5L Automatic Spout Pouch Filling & Capping Machine – Product Introduction

1. Product Overview

The 1.5L Automatic Spout Pouch Filling & Capping Machine is a high-performance automated packaging solution designed specifically for large-capacity liquid and semi-liquid products. As consumer preferences increasingly shift toward convenient, lightweight, and resealable packaging, spout pouches (also known as stand-up pouches or Doypacks) have emerged as a dominant packaging format across food, beverage, and daily chemical industries. This machine is purpose-built to address the growing market demand for 1L and 1.5L large-capacity packaging, delivering high-speed, precise, and intelligent filling and capping operations.

The machine integrates filling and capping into a seamless, fully automated workflow, capable of completing the entire production sequence—from pouch feeding and opening to quantitative filling, cap feeding, screw capping, and finished product output—without manual intervention. It is an ideal solution for manufacturers seeking to scale up production, reduce labor costs, and ensure consistent packaging quality.

2. Core Features & Advantages

2.1 Fully Automated Production Workflow

The machine achieves a closed-loop automated process that includes: pouch feeding → pouch opening → quantitative filling → spout cleaning → cap feeding → screw capping → finished product output. This end-to-end automation eliminates human error, significantly improves production line efficiency, and optimizes workforce allocation. Operators only need to set parameters and monitor the process, substantially reducing dependency on manual labor.

2.2 Large-Capacity Processing Capability

Specifically engineered for 1L and 1.5L large-capacity spout pouches, the machine effortlessly handles family-size and bulk packaging requirements. With a wide filling range from 30ml up to 2500ml, it offers exceptional flexibility to accommodate various product specifications—from sample sizes to large family packs—enabling manufacturers to diversify their product lines without investing in multiple machines.

2.3 High-Precision Quantitative Filling

The machine employs advanced quantitative filling technology, utilizing high-precision sensors and intelligent control systems to achieve exceptional filling accuracy. Errors are typically controlled within ±1ml. For applications requiring even greater precision, servo-driven gear pump technology can achieve filling accuracy of 0.5%–1%. This precision minimizes raw material waste—reducing material loss to under 1%—while ensuring consistent net content across every pouch, meeting the most stringent quality standards.

2.4 Reliable Screw Capping & Leak Prevention

The capping system features an automatic cap sorting and feeding mechanism that aligns caps to the spout for secure and precise locking. Equipped with servo and electromagnetic dual-drive capping technology, the machine delivers precisely controllable and uniformly consistent capping torque. The capping force can be adjusted according to different cap types and specifications, ensuring tight sealing without over-tightening or damage. In rigorous transportation simulations, products packaged by this machine achieved a leak rate below 0.1%, significantly reducing product loss during storage and transit.

2.5 Intelligent Control & Safety Features

The machine is equipped with an advanced PLC control system and an intuitive touchscreen interface, allowing operators to easily input product specifications, adjust packaging speeds, and monitor real-time production status. Key intelligent features include:

• No pouch, no fill: Photoelectric detection prevents filling when no pouch is present

• No cap, no cap: Automatic cap detection triggers停机 if caps are missing

• Anti-drip nozzles: Prevents dripping and keeps pouch spouts clean

• Automatic cap sorting: Integrated cap feeding system ensures smooth operation

Additionally, the machine features organic glass safety screens to protect operators during high-speed operation.

2.6 Wide Compatibility & Scalability

The machine is compatible with various pouch designs and cap types, as long as the spout and cap dimensions are consistent. The modular structure design allows for quick parameter adjustments and mold changes to accommodate different pouch sizes and materials. Optional add-on modules include:

• Nitrogen flushing for product preservation

• Automatic date coding

• Finished product sorting and collection

This flexibility enables manufacturers to quickly adapt to changing market demands and produce diverse product types.
