Product Introduction
The L50N New Small Vertical Liquid Three-Side Seal Packaging Machine represents a pinnacle of precision and efficiency in modern packaging automation. Engineered for versatility and reliability, this advanced machine integrates a sophisticated 7-inch touchscreen interface and a programmable logic controller (PLC) system to deliver seamless bilingual operation, comprehensive error diagnostics, and intuitive self-monitoring capabilities. Designed to handle a diverse range of materials from powders and granules to viscous liquids and sauces, it employs a modular architecture that facilitates rapid conversion between three-side and four-side sealing configurations. The core of its operation relies on a stepper motor-driven bag puller system synchronized with precise PID temperature control, ensuring consistent and hermetic seals on every package. Constructed primarily from food-grade 304 stainless steel with integrated acrylic safety guards, the machine prioritizes hygiene, operational safety, and long-term durability, making it an indispensable asset for demanding production environments.
Product Features
This packaging machine is distinguished by a suite of innovative features that collectively enhance productivity, accuracy, and user experience. Its intelligent control system provides clear visual prompts and diagnostics in multiple languages, significantly reducing setup time and operator error. The modular design philosophy extends beyond sealing types to include quick-change metering pumps—such as mechanical piston, magnetic, gear, or high-pressure variants—enabling swift adaptation to different product viscosities and packaging requirements. A high-performance rotary cutter ensures clean, precise bag separation, while the integrated elephant trunk forming device guarantees consistent and effortless pouch shaping. The machine’s robust framework, featuring a welded stainless steel chassis and a brushed exterior finish, is complemented by transparent acrylic covers equipped with safety interlock switches, ensuring full compliance with international food safety and industrial hygiene standards.
Versatile and Adaptable Performance
Engineered for maximum flexibility, the machine effortlessly transitions between packaging powders, liquids, granules, tablets, and semi-solid products. This adaptability is achieved through interchangeable metering systems and tool-less adjustment mechanisms for bag dimensions, allowing production lines to switch between different products and pouch styles with minimal downtime. Such versatility makes it an ideal solution for manufacturers producing multiple product lines or requiring frequent batch changes.
High-Speed Precision Engineering
Capable of achieving speeds of up to 100 cuts per minute with metering accuracy within ±1–3%, the equipment maintains exceptional consistency in bag size, seal integrity, and cut quality. The stepper motor-driven transport system ensures smooth, indexed bag movement, eliminating slippage and misalignment. Coupled with the rotary cutting mechanism, it delivers precisely separated packages with clean, finished edges, enhancing both product presentation and shelf appeal.
Durable and Hygienic Construction
Every component in contact with the product is fabricated from corrosion-resistant 304 stainless steel, ensuring easy cleaning and preventing contamination. The machine’s welded frame provides exceptional structural stability, while modular sealing elements are designed for extended service life and straightforward maintenance. The inclusion of clear acrylic protective covers with door detection sensors safeguards operators without obstructing the view of the packaging process, aligning with the highest standards of workplace safety and sanitary design.
