Vertical Form-Fill-Seal Packaging Machine KL320

The Keypack Intelligent KL-320 Vertical Form-Fill-Seal Machine is a compact VFFS Machine engineered for precise metering and packaging of granular, powder, block, and liquid materials. It delivers a packaging speed of 40–100 bags/min with PLC servo control and intelligent temperature sealing, supporting pillow bags, triangular bags, and hanging-hole bags. Ideal for food, powder, and liquid packaging lines requiring stable output and flexible bag-style switching.

Product Overview

The Keypack Intelligent (Kunbupack) KL-320 Vertical Packaging Machine is a single-unit automatic metering packaging machine designed for small to medium-scale production environments. Driven by a PLC servo system, pneumatic control system, and a large-display touchscreen interface, the KL-320 achieves high control accuracy and operational reliability across a wide range of material types and bag formats.

The machine's intelligent temperature controller ensures consistent sealing quality — producing neat, smooth seals across every cycle. Its touchscreen interface stores packaging parameters for multiple product types, enabling fast product changeover without manual re-configuration. A built-in fault display system assists operators in identifying and resolving issues promptly, reducing unplanned downtime.

With support for pillow bags, hanging-hole bags, and triangular bags, the KL-320 Back-Seal Vertical Packaging Machine offers flexible bag-style customization to meet diverse end-market requirements. Safety protection devices are integrated throughout, meeting standard enterprise safety management requirements for automatic packaging equipment.

Key Features and Machine Characteristics

• Intelligent Temperature Control: Precision temperature controller maintains consistent sealing temperature across production runs, delivering smooth and uniform seal quality for food, powder, and liquid packaging.
• PLC Servo + Touchscreen Drive System: The integrated PLC servo system, pneumatic control, and large-display touchscreen form the core control architecture — improving overall machine precision, reliability, and ease of operation.
• Multi-Product Parameter Storage: The touchscreen interface stores packaging process parameters for multiple product types. Switching between products requires no manual re-setting, reducing changeover time on mixed production lines.
• Multiple Bag Style Support: Configurable for pillow bags, hanging-hole bags, and triangular bags — adaptable to customer-specific packaging requirements across food, snack, and powder segments.
• Integrated Fault Display System: Real-time fault indication assists operators in identifying and resolving equipment issues quickly, supporting continuous production with minimal interruption.
• Safety Protection Devices: Comprehensive safety guarding is built into the machine design, complying with standard enterprise safety management requirements for automatic packaging equipment.

Application Areas

• Food packaging: Granular and irregular block materials including candies, puffed foods, small biscuits, roasted nuts, dried fruits, and granulated sugar — metered and sealed into pillow or hanging-hole bags at up to 100 bags/min.
• Powder packaging: Free-flowing and fine powder materials such as milk powder, milk tea powder, starch, and seasoning blends — packaged with consistent weight accuracy via the metering system.
• Liquid and semi-liquid packaging: Sauces, condiments, and beverages filled and sealed with the intelligent temperature-controlled sealing unit.
• Frozen food packaging: Quick-frozen food items packaged in sealed pillow bags suitable for cold-chain distribution.
• Snack and confectionery lines: Suitable as a Granular Packaging Machine or Food Packaging Machine for small to medium snack production facilities requiring flexible bag-style output.
• Seasoning and nutraceutical powder lines: Applicable as a Powder Packaging Machine for starch, seasoning, and similar dry powder materials with low to moderate moisture content.
