Product Overview

The Keypack Intelligent Liquid Pouch Feeding Machine for Pre-made Bags is a semi-automatic pre-made pouch filling and sealing machine designed for accurate metering and hygienic packaging of liquid products. It is widely used for food liquid packaging, pharmaceutical liquid packaging, and chemical liquid filling, including mouthwash, sauces, seasonings, traditional Chinese medicine drinks, health drinks, and other liquid or semi-liquid products.
This pre-made pouch packaging machine integrates pouch feeding, liquid filling, and sealing into one stable system. With PLC control, frequency conversion speed regulation, and compatibility with multiple liquid filling pumps, the machine provides reliable performance for manufacturers seeking a flexible liquid filling machine for pre-made pouch applications. It is suitable for semi-automatic production lines and can be expanded into an automatic liquid packaging line with supporting equipment.

Key Features and Machine Characteristics

• PLC Control System with Touchscreen HMI
  The Keypack Intelligent (Kunbupack) pre-made pouch filling machine is equipped with a PLC control system and human-machine interface (HMI), allowing operators to easily set parameters, monitor operation status, and ensure stable control during liquid filling and pouch sealing processes.

• Frequency Conversion Speed Regulation
  A frequency conversion speed control device enables flexible speed adjustment within the specified range, supporting different production capacities and improving adaptability for various liquid packaging requirements.

• Automatic Pre-made Pouch Width Adjustment
  The machine supports convenient pouch width adjustment via a rocker mechanism, enabling fast changeover between different pre-made bag sizes and improving efficiency in pre-made pouch packaging operations.

• Oil-Free Vacuum Pump for Clean Operation
  An oil-free vacuum pump is adopted for pouch handling, avoiding environmental pollution and ensuring clean, stable operation. This design is especially suitable for food-grade liquid packaging and pharmaceutical liquid filling applications.

• Food-Grade 304 Stainless Steel Construction
  All parts in contact with liquid materials are made of 304 stainless steel, meeting food hygiene standards. This makes the machine suitable for food liquid packaging, cosmetic filling machines, and chemical liquid filler applications.

• Compatible with Multiple Liquid Filling Pumps
  The machine can be combined with rotor pumps, pneumatic piston pumps, and other liquid filling equipment to form a semi-automatic or automatic liquid filling and packaging line, accommodating different liquid viscosities and product characteristics.
