3.5kw Automatic Liquid Packing Machine Heavy Duty Liquid Filling Packing Machine QNLP-BS420

QNLP-BS420 Automatic Liquid Filling & Packaging Machine | Heavy-Duty & Long Service Life

The QNLP-BS420 automatic liquid packaging machine is a heavy-duty, long-lifespan industrial filling and packaging solution specially optimized for high-viscosity liquids, emulsions, creams and special industrial adhesive materials. Specially suitable for waterproof emulsion, building waterproof coatings and tile back glue quantitative packaging, this all-round packaging machine features premium industrial build quality and ultra-long service cycle. Built to withstand long-hour continuous industrial operation, it delivers stable, consistent and low-maintenance performance, making it a durable long-term investment for food, daily chemical and construction material production lines.

Superior build quality and outstanding durability are the core advantages of this equipment. The whole machine adopts full 304 stainless steel structure with excellent waterproof and protective properties. Unlike ordinary iron-frame machines that are prone to rust, corrosion and structural aging in humid and material-splashing working environments, its sturdy stainless steel body resists water erosion, material adhesion and daily mechanical wear effectively. This professional industrial-grade structure greatly extends the machine’s service life, ensuring stable performance for years of continuous operation and helping enterprises reduce equipment replacement costs and long-term investment budgets.

Engineered for stable and high-efficiency packaging, the machine is equipped with a high-precision servo film pulling system. The servo motor driven automatic film rolling device realizes fast, accurate and self-correcting film feeding, ensuring precise bag sizing and zero deviation during long-time high-speed operation.

Matching the upgraded servo sealing device, the machine achieves faster and more stable sealing movement, with firm and neat sealing edges, effectively avoiding material leakage for thick and viscous materials such as waterproof glue and emulsions.

Equipped with a high-quality automatic coding printer, the machine supports clear printing of production dates, shelf life and batch numbers. The printing effect is pollution-free, fade-proof and compliant with formal product packaging standards. The standardized electric control box features neat and classified circuit layout, which avoids circuit aging and short circuit problems caused by long-term use, further improving equipment stability and service life. The intuitive microcomputer touch panel simplifies all operational adjustments, enabling easy operation and fast parameter switching for different materials.

Boasting ultra-wide application versatility, the machine supports free sample testing and adapts to various liquids and pastes. It not only meets the quantitative packaging needs of construction waterproof emulsion and tile back glue, but also perfectly fits daily chemical and food materials including shampoo, body wash, face cream, fruit juice and jam. With stable working parameters, it supports a maximum film width of 420mm, fixed bag size of 400mm * 300mm, and a packaging speed of 30–60 bags per minute.

Powered by a stable 3.5kw 220V power system, this 600kg heavy-duty machine features robust structural stability and low failure rates. Combining waterproof design, durable stainless steel build, stable servo operation and low maintenance cost, the QNLP-BS420 packaging machine is a high-quality, long-lasting industrial packaging equipment for diversified liquid and paste packaging scenarios.
