Product Overview

The Keypack Intelligent Rotary Feeding Pre-made Bag Packaging Machine is a high-efficiency automated solution designed for packaging single products that are difficult to meter, including chicken legs, duck necks, duck feet, corn, zongzi (glutinous rice dumplings), sausages, and other irregular solids. The machine combines a circular feeder with manual loading and performs automatic bag opening, filling, and sealing using a multi-station rotary mechanism. Ideal for snack foods, frozen foods, pet foods, and specialty products, the system ensures high-speed, precise volumetric filling with minimal waste, making it suitable for manufacturers seeking efficient, hygienic, and reliable pre-made bag packaging solutions.

Key Features and Machine Characteristics

High-Speed Multi-Station Operation

The Keypack Intelligent rotary pre-made bag packaging machine features eight rotary stations operating simultaneously, enabling fully automated bag feeding, filling, and sealing. This multi-station rotary indexing design maximizes output and ensures precise, consistent product placement, ideal for high-speed snack, frozen food, and pet food production lines.

PLC Control and Touchscreen Operation

Equipped with an advanced PLC control system and user-friendly touchscreen interface, operators can easily adjust packaging parameters such as bag size, filling volume, and sealing settings. This intuitive control ensures consistent quality while reducing human error and operational training time.

Food-Grade Construction

All machine parts in contact with products are manufactured from 304 stainless steel, meeting food safety and hygiene standards. This construction is compliant with GMP requirements and ensures safe packaging for snacks, frozen foods, pet foods, and other specialty products.

Optional Coding and Traceability

The machine can be equipped with a coding device for printing production dates, batch numbers, or other product information directly on the bags. This ensures traceability, improves regulatory compliance, and enhances the professional presentation of packaged goods.

High Yield and Reduced Waste

With an automatic feeding and volumetric filling system, the Keypack Intelligent (Kunbupack) rotary bag packaging machine achieves a finished product rate exceeding 99.5%, significantly reducing waste caused by manual operations and minimizing defective product rates.
