Automatic Open-Mouth Bagging Machine for Bagging & Palletizing System

3CM-P

Fully automatic open-mouth bagger for filling granular and powder products into pre-made open-mouth bags

The automatic open-mouth bagging machine is designed for flexible, steady, and continuous operation in bulk-material packaging lines. It handles a wide range of bag types, including paper bags, PE heavy-film bags, and laminated woven bags. The system supports flat-top bags, M-fold bags, and envelope-type bags within a 20–50 kg filling range. With an output of 500–800 bags per hour, it is a practical solution for chemical plants, feed mills, grain processors, and other operations that require consistent and dependable bag handling.

Features

Handles 20–50 kg bags at 500–800 bags/hr: Supports medium to high-throughput operations while maintaining stable filling performance.
High-efficiency automatic bag presentation: The auto-bag magazine and pick-up system are built for smooth, continuous operation in busy production environments.
Independent control and protection for each functional unit: Every module includes coordinated control and safety mechanisms to maintain steady, uninterrupted workflow.
Motor-driven actuation for improved operating efficiency: Servo-based movement delivers cleaner bag transfer, more precise positioning, and better overall consistency.
Recommended pairing with KS-series heat sealing systems: Combining the 3CM-P with a KS heat sealer enhances the appearance of the sealed bag and helps prevent leakage and air ingress.
