Automatic Open-Mouth Bagging Machine

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

The automatic open-mouth bagging machine is built for stable, continuous bagging performance across a wide range of packaging materials. It handles paper bags, PE heavy-film bags, and laminated woven bags, and supports flat-top, M-type, and envelope-style bag designs. This flexibility makes it suitable for chemical, feed, grain, and other bulk-material applications that require consistent filling accuracy and reliable downstream integration.
