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.
