Product Overview

The Keypack Intelligent (Kunbupack) Pre-made Pouch Liquid Filling Machine represents a specialized automatic liquid weighing and bagging solution for premade bag filling with integrated liquid filling system and combination weigher compatibility. This weighing type liquid packing machine series offers five models (KB8-200, KB8-260, KB8-300, KB8-420, KB10-200) engineered to handle pre-made pouches with width ranges from 80mm to 420mm and length options from 100mm to 500mm, accommodating fill weights from 10g to 4000g depending on model configuration.

The system features 304 stainless steel construction for all liquid-contact surfaces, ensuring compliance with food hygiene standards, pharmaceutical GMP requirements, and cosmetic manufacturing regulations. The liquid filling system provides consistent volumetric accuracy for various viscosity liquids including sauces, edible oil, shampoo, lotion, liquid detergent, syrup, chemical liquids, mouthwash, condiments, traditional Chinese medicine beverages, and health drinks. The automatic bag feeding system with drip-free nozzle technology manages bag opening, precise liquid filling, and leak-proof sealing operations with minimal manual intervention.

Integration capability with upstream liquid feeding equipment including rotor pumps and pneumatic piston pumps enables complete automated liquid packaging lines for food liquid packaging, cosmetics filling machines, chemical liquid fillers, and pharmaceutical liquid packaging applications requiring precise dosing and contamination-free processing.

Key Features and Machine Characteristics

• PLC Control with HMI Interface: User-friendly programmable logic controller with human-machine interface enables simple operation, recipe storage for different liquid products, and real-time production monitoring. This reduces operator training requirements and ensures consistent packaging quality across production shifts, particularly valuable for multi-product cosmetics filling machine and food liquid packaging operations requiring frequent product changeovers between sauces, edible oil, and liquid detergent formulations.
• Variable Frequency Speed Control: Frequency conversion technology allows stepless speed adjustment within specified ranges (8-80 bags/minute depending on model and liquid characteristics). This optimizes throughput for different viscosity liquids including shampoo, lotion, syrup, and chemical liquids while minimizing product waste and reducing energy consumption in pharmaceutical liquid packaging and cosmetics filling applications.
• Automatic Bag Width Adjustment: Hand-crank operated bag width adjustment mechanism with precision positioning enables quick changeover between different premade pouch sizes without requiring tools. This minimizes downtime during product transitions and supports flexible multi-SKU production scheduling for food liquid packaging lines handling various sauce containers, edible oil pouches, and liquid detergent packages.
• Oil-Free Vacuum Pump System: Eliminates oil contamination risks in the production environment, particularly critical for food liquid packaging, cosmetics filling machines, and pharmaceutical applications requiring clean processing conditions. The oil-free vacuum technology ensures regulatory compliance and prevents product contamination from vacuum system maintenance in mouthwash packaging, health drink filling, and chemical liquid filler operations.
• 304 Stainless Steel Liquid Contact Parts: All liquid-contact surfaces including filling nozzles, liquid pathways, and drip-free nozzle components manufactured from 304-grade stainless steel meet international food safety standards. This material selection resists corrosion from acidic sauces, alkaline liquid detergents, and chemical liquids, facilitates cleaning validation protocols for pharmaceutical liquid packaging, and ensures long-term durability in cosmetics filling machine applications handling shampoo, lotion, and syrup products.
• Drip-free Nozzle and Leak-proof Sealing Technology: Advanced liquid filling system with drip-free nozzle design prevents product waste and maintains clean packaging appearance for premium cosmetics filling and food liquid packaging applications. The leak-proof sealing mechanism ensures product integrity for liquid detergent, edible oil, and pharmaceutical liquid packaging requiring extended shelf life and transportation durability, while high accuracy weighing maintains consistent fill weights across production runs.
• Rotor Pump and Pneumatic Piston Pump Integration: Compatible with rotor pumps for high-viscosity products like thick sauces and lotion, and pneumatic piston pumps for precise dosing of low-viscosity liquids including mouthwash, syrup, and chemical liquids. This modular integration creates consistent material flow, reduces manual handling, and improves production efficiency for automated liquid packaging lines serving food, cosmetics, pharmaceutical, and chemical industries.
