Weighing and Packaging Machine

Keypack Intelligent Weighing Vertical Form-Fill-Seal Machine designed for accurate packaging of irregular block and granular materials. It delivers 5-100 bags per minute with PLC servo control, intelligent temperature management, and multihead weigher compatibility. Ideal for food weighing applications, frozen food packaging, and snack production lines requiring reliable VFFS machine performance.

Product Overview

The Keypack Intelligent Weighing VFFS Machine is an advanced vertical packaging machine engineered for precise weighing and automated bag forming operations. As a comprehensive vertical form-fill-seal machine, it integrates smart weighing technology with servo-driven film handling to deliver consistent packaging performance across six model configurations (KL-320, KL-420, KL-520, KL-620, KL-820, KL-1250).

This Keypack Intelligent (Kunbupack) Vertical Packaging Machine combines combination weigher compatibility, pneumatic control systems, and touchscreen operation to automate the complete packaging workflow. From weighing and feeding to bag making, sealing, gas flushing or evacuation, date printing, and finished product conveying, the system handles diverse granular and block-shaped materials with minimal operator intervention.

Equipped with intelligent temperature controllers for accurate sealing and PLC servo systems for enhanced control precision, this VFFS machine supports pillow-type bags and hanging-hole bag formats. The touchscreen interface stores packaging parameters for multiple products, enabling fast changeover without re-configuration and improving production efficiency across food weighing and hardware pack applications.

Key Features and Machine Characteristics

• Integrated Safety Protection: Equipped with safety guards and emergency stop systems to meet enterprise safety management requirements for automated packaging equipment.
• Intelligent Temperature Control: Smart temperature controllers ensure precise sealing temperature regulation, producing neat, smooth, and consistent seal quality across production runs.
• Advanced PLC Servo Control: Utilizes PLC servo system, pneumatic control, and large touchscreen interface as the core drive control, maximizing control precision, operational reliability, and intelligent automation for vertical packaging machine applications.
• Complete Automation with Weighing Integration: When configured with multihead weigher, combination weigher, or smart weighing systems, the vertical form-fill-seal machine automatically completes weighing, feeding, filling, bag-making, date printing, gas flushing or evacuation, finished product conveying, and automatic counting.
• Multi-Product Parameter Storage: Touchscreen control system stores packaging parameters for multiple products, allowing rapid product changeover without re-setting and improving production efficiency in food weighing operations.
• Fault Display System: Integrated diagnostic system assists operators in quick troubleshooting and timely resolution of machine faults, reducing downtime.
• Flexible Bag Format Options: Supports customization for pillow-type bags and hanging-hole bags to meet different packaging format requirements for retail and food service applications.
• Efficient Film Handling: Single-belt or double-belt film pulling systems ensure fast, stable operation with low friction and minimal wear, suitable for long-term VFFS machine operation and reducing film waste.

Application Areas

• Food Weighing and Snack Packaging: Candies, puffed foods, small biscuits, roasted nuts, dried fruits, and granulated sugar requiring accurate portion control with multihead weigher or combination weigher systems.
• Frozen Food Packaging: Quick-frozen foods, frozen vegetables, and frozen seafood products requiring gas flushing or vacuum-assist capabilities for extended shelf life.
• Irregular Block and Granular Materials: Non-uniform shaped products including confectionery, snack mixes, and specialty food items that benefit from smart weighing technology and gentle product handling.
• Hardware Pack Applications: Small hardware components, fasteners, and industrial parts requiring accurate counting and moisture-barrier packaging.
• Multi-Product Packaging Lines: Production environments requiring frequent product changeovers where touchscreen parameter storage and rapid format adjustment improve operational efficiency.
• Loss-in-Weight and Continuous Feeding Operations: Applications requiring consistent material flow and weight verification throughout the packaging cycle.
