Top Quality Hot Selling 8-Lane Liquid & Paste Quantitative Packaging Machine | High-Speed Back Sealing Packaging Equipment

Optimize your liquid and paste packaging workflow with our premium 8-lane quantitative filling and sealing packaging machine, model QNHC-460. Specially engineered for viscous paste and fluid material packaging, this industrial-grade automated equipment integrates precision dosing, intelligent sealing and flexible bag forming functions. It is ideal for mass production of daily chemical, food and condiment products, delivering ultra-high throughput and consistent packaging quality for medium and large-scale manufacturing lines.

Equipped with 8 independent working lanes, the machine achieves a stable maximum packaging speed of 200 bags per minute, drastically boosting daily production capacity compared to conventional multi-row packaging devices. It supports a maximum film width of 900mm, with adjustable bag dimensions ranging from 50–180mm in length and 20–105mm in width. Adopting professional long and short screw metering methods, it ensures precise quantitative filling for various fluid and viscous materials, effectively solving uneven filling and material overflow issues unique to liquid and paste products.

Versatile bag making and film conveying systems lay a solid foundation for high-quality packaging. The precision bag making device accurately controls bag size, shape and sealing standard, compatible with diverse packaging materials including plastic film and paper packaging materials. Operators can freely adjust bag specifications and shapes to match different product packaging standards. Matched with a premium hanging film bracket, the equipment avoids film scratching, curling and jamming. The sturdy structural design ensures smooth and stable film traction, eliminating material deviation during continuous high-speed operation.

Consistent and reliable sealing performance guarantees product packaging integrity. The professional sealing unit adopts AI bus temperature intelligent control technology, achieving ultra-precise and constant temperature regulation. It delivers tight and flawless back sealing results, effectively preventing liquid and paste leakage, seepage and air ingress, and extending the shelf life of packaged products. All material contact parts adopt 304 stainless steel configuration, and a customizable stainless steel feeding conveyor is available to adapt to diverse packaging production demands, featuring corrosion resistance, easy cleaning and long service life.

The machine adopts standardized and orderly built-in circuit system layout, which optimizes chassis heat dissipation and improves equipment detection accuracy and operational stability while facilitating daily inspection and maintenance. Equipped with a programmable logic controller with multi-language support, the intuitive operating panel allows operators to store multiple sets of production parameters. One-click parameter switching enables fast production conversion, greatly improving production flexibility.

With 220V 50Hz voltage and 7.5kw power, and a stable structure weighing 1100kg, this 8-lane packaging machine balances high efficiency and operational stability. It is a professional, low-maintenance automated packaging solution for mass liquid and paste packaging production.
