CMBM-320WP is a Food paper bag and V bottom paper bag making machine designed for bakery bags, bread bags, takeaway bags, food packaging bags and V bottom paper bags.
To configure CMBM-320WP accurately, buyers should provide food bag size, paper material, bottom style, window or printing needs and target capacity. CHAMPION reviews these inputs against the finished bag sample before confirming the machine layout.

Machine Description
Bag Bottom Forming Module
Blowing Bottom Opening Mechanism: Solenoid valves control the front and rear air blowing mechanisms. High-pressure air precisely opens the bag bottom, preforming a hexagonal shape for the bottom folding process.
Hot Sealing Unit: Instantaneous high-temperature lamination creates a sealed edge, ensuring water and leak resistance.
Intelligent Control System
Human-Machine Interface: A touchscreen provides centralized control, displaying real-time fault alerts and allowing fine-tuning of parameters (such as temperature and speed).
PLC + Photoelectric Detection: A photoelectric sensor coupled to a servo motor enables functions such as no-material shutdown and bag clamping detection.
Multifunctional Actuator
Clamping System: The folding and bag opening clamping plates work together to secure the bag. A vibration mechanism compacts the contents and reduces air in the bag.
Valve Tape Mechanism: Automatically applies reinforced liner paper to improve load-bearing capacity.
Machine Features
Seamless production chain: The process of loading, opening the bottom, folding the bottom and sticking the bottom are integrated to reduce manual intervention and greatly improve efficiency.
Hexagonal bottom forming: Front and rear high-pressure air blowers precisely open the bottom, creating a hexagonal structure. Combined with hot-stamping technology, this system provides physical leak prevention.
Dynamic adjustment mechanism: The folding clamping plate is equipped with a gap/height adjustment module (limiting blocks + telescopic rod) to accommodate different paper weights.
The air blow angle is adjustable (rotating rod + sprocket drive) to prevent airflow deviation and bag shape distortion.
Energy-saving design: An automatic lubrication system reduces energy consumption, and a variable-frequency motor drives the material feeding process to reduce idling losses.
Specialized for laminated paper bags: Compatible with waterproof materials such as laminated kraft paper and medical paper, the hot-stamped lamination layer enhances impermeability.
Glue-free process: Instead of traditional gluing of the sides, hot-stamping is used to form the sides, eliminating the risk of cracking.
