Key Features and Machine Characteristics

Multi-Station High-Speed Packaging

The Keypack Intelligent Automatic Premade Bag Vacuum Packaging Machine features a rotary full-automatic bag feeding design with two separate rotary bodies: one for filling and one for vacuum sealing. The filling system operates with intermittent rotation, while the vacuum system runs continuously, ensuring smooth multi-station, high-speed vacuum packaging of food products. This setup supports large-volume production while maintaining consistent quality and efficiency.

Quick and Flexible Bag Size Changeover

The width of the automatic bag-feeding device can be adjusted automatically in a single step, allowing fast and flexible changeovers between different bag specifications. This feature reduces downtime and increases productivity for multi-product food packaging lines.

Hygienic and Food-Safe Construction

All parts in contact with food or packaging bags are made of high-quality stainless steel or materials meeting food hygiene standards. The vacuum chamber is fully washable, ensuring compliance with food processing hygiene requirements and maintaining the highest standards of food safety.

Low Packaging Material Loss and Premium Presentation

The machine uses prefabricated vacuum bags with precise patterns and excellent sealing quality, minimizing material waste. No bag is filled or sealed incorrectly, and bags can be reused if necessary, improving overall product grade and consistency.

User-Friendly Operation and Intelligent Control

Equipped with an advanced PLC and POD (touchscreen) control system, the Keypack Intelligent (Kunbupack) Automatic Premade Bag Vacuum Packaging Machine allows intuitive man-machine interaction. The system automatically adjusts the angle and timing of pneumatic components, and includes a sealing temperature monitoring function with alarms for heating tube or thermocouple failure, ensuring operational safety and consistent sealing quality.
