Automatic 50ml Liquid Sachet Filling & Pouch Packing Machine
This advanced automatic liquid filling and sachet packing machine represents a significant leap in small-dose packaging technology, engineered specifically for the precise, hygienic, and high-volume packaging of liquid products ranging from 1 to 50 milliliters. It masterfully consolidates the entire packaging process—including precise liquid metering via pump dosing, film forming, hermetic sealing, and the final output of finished sachets—into a single, streamlined, and compact system. The machine offers versatile sealing options, supporting both three-side and four-side seal formats, making it the ultimate solution for creating professional single-serve packages. Ideal for a diverse array of products such as sauces, beverages, edible oils, and various chemical liquids, it empowers manufacturers to transition seamlessly from inefficient manual or semi-automatic operations to a fully automated, production-ready pouch packaging line. Featuring a robust stainless-steel control panel and a precision servo-driven film pulling mechanism, this machine delivers unparalleled consistency, significantly reduces labor dependency, and minimizes material waste, thereby optimizing overall operational efficiency and product quality.
Product Advantages
Exceptional Product Versatility: Designed with broad compatibility in mind, this machine is perfectly suited for a wide spectrum of liquid products commonly distributed in sachet form. This includes, but is not limited to, soy sauce, vinegar, fruit juices, milk, wine, cooking oils, beverage concentrates, and a variety of non-corrosive chemical solutions. The core pump-based dosing mechanism is specifically calibrated for small-volume applications, ensuring stable and repeatable quantitative filling that maintains batch-to-batch consistency and product integrity.
Precision Pump Filling Technology: At the heart of the machine lies an optimized liquid pump dosing system, meticulously engineered for the 1–50 ml filling range. This system guarantees exceptional volume control accuracy, virtually eliminating issues of overfill or underfill. This precision not only ensures strict compliance with product specifications but also directly contributes to reduced giveaway costs and enhanced customer satisfaction through consistent portioning.
High-Efficiency, User-Friendly Operation: Centralized control is achieved through an intelligent PLC system paired with a wide, intuitive touch-screen Human-Machine Interface (HMI). This setup allows for straightforward parameter setting, rapid product changeovers, and smooth daily operation with minimal training. The automated workflow drastically reduces reliance on operator skill and experience, while maintaining a stable and high output rate to meet demanding production schedules.
Servo-Controlled Film Pulling for Superior Stability: The incorporation of a servo-controlled film pulling system sets this machine apart. It ensures precise and steady control over bag length, even at elevated operational speeds. This advanced technology supports superior registration accuracy and contributes to a marked improvement in overall packaging quality and appearance compared to conventional mechanical pulling systems, reducing film tension issues and misfeeds.
Reliable Sealing with Minimized Waste: A robust horizontal sealing system delivers consistent, high-strength seals for common laminated packaging films. Integrated smart alarm and protection logic continuously monitors the machine’s status, enabling early detection of abnormal conditions such as film jams or seal failures. This proactive approach significantly reduces unplanned downtime and prevents unnecessary waste of both packaging film and valuable product.
Complete Integrated Processing Line: The machine functions as a comprehensive, end-to-end packaging solution. It seamlessly integrates multiple stages: product feeding (when paired with a compatible supply system), precise measuring, accurate filling, reliable sealing, optional date/lot code printing, optional gas flushing or vacuum charging, automatic counting, and final product discharge. This integration creates a streamlined, continuous sachet production line that maximizes throughput and minimizes manual intervention.
Durable and Hygienic Construction: Built with longevity and cleanliness in mind, the machine features a predominant stainless-steel panel design. This construction not only enhances durability and resistance to corrosion but also facilitates easy and thorough cleaning and sanitization procedures, making it perfectly suited for the stringent hygiene standards required in food, beverage, and daily chemical manufacturing environments.
Flexible Pouch Format Configuration: The machine offers adaptable packaging styles to meet diverse market needs. While three-side sealing is standard, it can be readily configured for four-side seal styles based on specific packaging requirements. This flexibility enables brands to create sleek, professional single-dose packages that are ideal for retail shelves, takeaway services, promotional sampling, and controlled portion distribution.
