Product Features

The Automated Liquid Sachet and Stick Pack Production Line is distinguished by its advanced engineering, robust construction, and intelligent design, offering manufacturers a reliable and flexible packaging solution.

• High-Speed Dual-Format Packaging: This versatile line is capable of producing both single-dose sachets and stick packs on a single integrated platform. The quick-format changeover feature minimizes downtime, allowing manufacturers to efficiently cater to diverse market needs and product presentations.
• Precision Volumetric Filling System: At the heart of the line is an advanced filling system utilizing servo-driven piston or pump technology. It guarantees exact, consistent liquid dosage for every sachet and stick pack, drastically reducing product giveaway and ensuring uniform quality across all units.
• Hygienic & Aseptic Design Philosophy: Constructed with food-grade 304 or 316 stainless steel in all critical product contact zones, the line prioritizes cleanliness. The design minimizes crevices and features enclosed panels where applicable, making it suitable for sensitive products in cosmetics, pharmaceuticals, and food.
• End-to-End Automation: The entire process is fully automated, encompassing film unwinding, forming, filling, sealing, date/batch coding, and counting. This significantly reduces labor dependency, enhances production speed, and minimizes the risk of contamination from human intervention.
• Intelligent Control System: Equipped with a user-friendly PLC and a large HMI (Human-Machine Interface) touchscreen. Operators can easily set, monitor, and adjust all parameters, track production metrics in real-time, and receive immediate fault diagnostics for maximum uptime and operational simplicity.
• Robust and Reliable Performance: Built with high-quality industrial components and a rigid frame, the line is engineered for continuous, 24/7 operation in demanding environments. This ensures long-term reliability, durability, and a low total cost of ownership.
• High Customization Flexibility: The line can be tailored to handle a wide range of liquid viscosities—from watery serums to viscous gels—and can accommodate various packaging films, including high-barrier laminates for extended shelf life. It is designed for easy integration into existing production workflows.
