High-Precision Automated Liquid Sachet Filling and Sealing System

The High-Precision Automated Liquid Sachet Filling and Sealing System, engineered by Packmate (GuangDong) Co., Ltd., represents the pinnacle of modern packaging technology. This fully integrated, turnkey system is specifically designed for the high-speed, accurate, and hygienic packaging of premium liquid products such as cosmetic serums, pharmaceutical essences, and other sensitive fluids. It automates the entire packaging sequence—from precision film unwinding and sachet forming to exact volumetric filling, hermetic sealing, and final cutting. The result is the production of uniform, professional-grade, and leak-proof single-dose sachets that ensure product integrity, extend shelf life, and elevate brand perception. Built on over three decades of engineering expertise, this system is the definitive solution for manufacturers seeking to scale production, achieve unparalleled filling accuracy, and minimize operational waste within a fully automated workflow.

Product Features

The system is engineered with a suite of advanced features that guarantee superior performance, operational simplicity, and long-term reliability.

Ultra-High Precision Servo Filling

  • Utilizes advanced servo-driven piston or pump filling technology to deliver exceptional volumetric accuracy, typically within ±0.5%.
  • Eliminates product giveaway and ensures every sachet contains a consistent, precise dose, which is critical for high-value cosmetic and pharmaceutical formulations.

End-to-End Automation

  • Provides a completely seamless operation from film roll feeding and automatic forming to filling, sealing, date/batch coding, and cutting.
  • Dramatically reduces labor dependency and costs, minimizes human contact for superior hygiene, and maximizes production line uptime and output.

Versatile Material & Format Compatibility

  • Designed to process a wide array of high-barrier laminated films (e.g., AL/PE, PET/AL/PE) and biocompatible materials.
  • Features modular tooling and quick-change mechanisms for rapid switchovers between different sachet sizes and shapes (3-side or 4-side sealed), offering exceptional flexibility for batch production.

Intelligent Control & Monitoring

  • Centered on a user-friendly PLC control system with a color touch-screen HMI (Human-Machine Interface).
  • Allows for easy parameter setting, real-time monitoring of production speed and counts, and swift diagnostics, simplifying operation and maintenance.

Robust & Sanitary Construction

  • Constructed with high-grade stainless steel (SS304/316) for all product-contact parts, complying with GMP and hygienic design standards.
  • The sanitary design facilitates easy and thorough cleaning, preventing contamination and making it ideal for sterile or cleanroom environments.
