Automated Liquid Filling and Sealing Line for Sachet and Stick Pack Packaging

Packmate (GuangDong) Co., Ltd. introduces its premier Automated Liquid Filling and Sealing Line, a complete turnkey solution engineered for the high-volume, precision packaging of free-flowing and viscous liquids into sachets and stick packs. This integrated production line represents the culmination of over three decades of expertise in intelligent packaging machinery, designed to deliver unparalleled efficiency, hygiene, and reliability for modern manufacturing facilities. It is the ideal system for producers seeking to automate their packaging process, minimize waste, ensure consistent product quality, and achieve maximum output with minimal operational complexity.

Product Features

The Automated Liquid Filling and Sealing Line is built with a focus on performance, adaptability, and user-centric operation. Its design incorporates advanced technologies to handle the demanding requirements of liquid packaging across various industries.

• High-Speed Multi-Lane Production: Engineered for maximum throughput, the system features synchronized multi-lane filling and sealing stations, dramatically increasing production capacity compared to conventional single-lane machines and optimizing your return on investment.
• Precision Servo-Driven Filling: Equipped with advanced servo-motor controlled piston fillers or precision pumps, the line guarantees exceptional dosing accuracy within a tight tolerance of ±1%. This ensures consistent portion control for every sachet or stick pack, reducing product giveaway and maintaining strict cost control.
• Hygienic & Durable Construction: All critical components in contact with the product are manufactured from high-grade, corrosion-resistant stainless steel. This not only meets global food safety and sanitary standards (such as GMP) but also allows for easy cleaning, sterilization, and ensures long-term durability with minimal maintenance.
• Rapid Format Changeover: The line is designed for operational flexibility, allowing for quick and tool-less changeovers between sachet and stick pack formats, as well as between different package sizes. This significantly reduces downtime and makes the system perfect for batch production of multiple products.
• Robust & Reliable Sealing System: Incorporates a high-performance heat sealing mechanism with precise digital temperature control. This technology creates strong, hermetic, and leak-proof seals on a wide range of laminated film materials, guaranteeing product integrity, preventing contamination, and extending shelf life.
• Intelligent PLC Control System: Operation is centralized through a user-friendly, color touch-screen Human-Machine Interface (HMI) powered by a programmable logic controller (PLC). The system allows for easy parameter setting, provides real-time monitoring of production data, and includes diagnostic functions for simplified troubleshooting and maintenance.
• Seamless Line Integration: This automated line is designed for complete system integration. It can be effortlessly connected to upstream equipment like mixing tanks or cooking kettles and downstream systems such as automatic cartoners or case packers, creating a fully automated, end-to-end packaging solution from raw material to final palletizing.
