It guarantees product integrity, maximizes shelf life, and delivers exceptional operational efficiency for global manufacturers seeking reliable and scalable packaging automation.

Product Features

The Automated Sachet Packaging Line is distinguished by its robust engineering and intelligent design, focusing on precision, protection, and productivity.

• Ultra-Precise Liquid Filling System: Equipped with advanced servo-driven piston fillers or precision peristaltic pumps, the system ensures volumetric accuracy for both low and high-viscosity liquids. This eliminates product giveaway, ensures compliance with strict label claims, and maintains consistent dose integrity across every sachet.
• Superior Barrier Protection & Airtight Sealing: The line is compatible with high-grade, multi-laminated films that provide an excellent barrier against oxygen, moisture, and light. Coupled with a robust thermal sealing mechanism, it creates a hermetic seal that effectively prevents oxidation, leakage, and contamination, preserving the potency, freshness, and sensory qualities of the packaged product.
• End-to-End Fully Automated Operation: From film roll unwinding and sachet forming to precise filling, sealing, date coding, and final cutting/counting, the entire process is automated. This design drastically reduces labor dependency, minimizes human intervention for enhanced hygiene, and ensures consistently high output quality with remarkable repeatability.
• Hygienic & Sanitary Construction: Built with food and pharmaceutical-grade stainless steel (AISI 304/316) for all product contact surfaces. The design prioritizes smooth contours and minimal dead zones to facilitate rapid product changeovers and thorough cleaning. Optional Clean-in-Place (CIP) and Sterilize-in-Place (SIP) systems are available to meet the highest sanitary protocols.
• Intelligent Control with User-Friendly HMI: Governed by a sophisticated Programmable Logic Controller (PLC) and a graphical Human-Machine Interface (HMI), the line allows for intuitive parameter setup, recipe storage, real-time production monitoring, and automated fault diagnosis. This ensures smooth operation, quick troubleshooting, and minimal downtime.
• High-Speed Production Efficiency: Engineered for rapid cycling, the packaging line achieves high output rates, significantly boosting production capacity to meet large-volume orders and demanding market schedules without compromising on precision or seal quality.
• Format Flexibility & Customization: The machine supports a wide range of sachet sizes, shapes (such as pillow, gusseted, or stand-up), and packaging materials. It can be seamlessly integrated with inline printing, coding, or vision inspection systems for adding batch numbers, expiry dates, QR codes, or logos directly onto the sachet film.
