Product Features

This automated line incorporates a suite of advanced technologies designed for precision, flexibility, and uncompromising quality in liquid packaging.

• High-Precision Volumetric Filling System: Employs advanced servo-driven piston or pump filling technology to guarantee extremely accurate and consistent dosing for every sachet or stick pack. This minimizes product giveaway and ensures each unit contains the exact specified volume of serum, crucial for cost control and brand consistency.
• Engineered for Viscous Fluids: Specifically designed to manage the unique flow characteristics of serums, gels, and lotions. The system prevents dripping, splashing, or stringing, maintaining a clean production environment and eliminating product waste on sealing jaws.
• Multi-Format Production Flexibility: Capable of producing both standard sachets and elongated stick packs on a single line. With quick-change tooling and recipes stored in the PLC, manufacturers can switch between formats efficiently to adapt to diverse market demands and product portfolios.
• Advanced Leak-Proof Sealing Technology: Features a robust heat sealing system with precise temperature and pressure control. It creates strong, hermetic, and tamper-evident seals on high-barrier laminated foil materials, ensuring extended shelf life and absolute protection against leakage, oxidation, and contamination.
• End-to-End Integrated Automation: The line seamlessly integrates all stages: roll film feeding, optional date/batch coding, precise pouch forming, accurate filling, hermetic sealing, clean cutting, and final counting/output. This full automation minimizes manual intervention, reduces labor costs, and maximizes throughput and consistency.
• Hygienic & Sanitary Design: Constructed with food-grade stainless steel for all product contact parts. The design follows sanitary principles with smooth surfaces and easy-access panels, facilitating quick and thorough clean-in-place (CIP) or washdown procedures to meet stringent GMP and cosmetic-grade production standards.
• Intelligent Control & Monitoring: Centrally controlled by a user-friendly PLC-based Human-Machine Interface (HMI). Operators can easily monitor and adjust all critical parameters—machine speed, filling volume, sealing temperature, and pressure—ensuring simple operation, real-time troubleshooting, and consistent production quality.
