Introduction to Polymer Open Mouth Bag Filling Machine Manufacturer
A Polymer Open Mouth Bag Filling Machine is designed to pack polymer granules and pellets into open mouth bags with stable weight accuracy, clean filling, and repeatable output. In polymer processing plants, consistent bag weights, low spillage, and controlled dust are essential for safe handling and smooth logistics. Samirika Group manufactures open mouth bag filling systems built for continuous operation, reliable feeding, and operator-friendly control. These machines support flexible configurations for different polymer grades, bag sizes, and packaging speeds, helping processors streamline bagging while maintaining product integrity from silo discharge to final sealing.
Working Principle and Process Flow of Polymer Open Mouth Bag Filling Machine
The operation starts when polymer material is discharged from a silo or hopper to the feeding system. A controlled feeder delivers polymer into a weigh hopper or directly to the filling spout, while load cells and the controller track weight in real-time. Once the set target is achieved, the feed stops automatically and the machine stabilizes the fill to minimize overfill and spillage. The filled bag is then supported for bag settling and transfer to downstream equipment such as a bag conveyor, stitching or heat sealing unit, and optional check weigher. This process ensures accurate weight control, clean bag mouth filling, and consistent throughput.
Types of Polymer Open Mouth Bag Filling Machines
- Net Weigher Open Mouth Bagger – Uses a weigh hopper for accurate pre-weighing before discharge into the bag.
- Gross Weigher Open Mouth Bagger – Weighs the bag during filling, suitable for balanced speed and accuracy needs.
- Gravity Feed Open Mouth Bagger – Best for free-flowing polymer granules where fast filling is required.
- Belt Feed Open Mouth Bagger – Works well for mixed-size pellets and controlled flow packaging.
- Vibratory Feed Open Mouth Bagger – Supports gentle, stable feed for certain polymer grades and reduced bounce-back.
