Introduction to Polymer Open Mouth Bagging Machine
A polymer open mouth bagging machine is built for fast, accurate and clean filling of open mouth bags with plastic granules, pellets, regrind and polymer powders. The system typically combines a net weighing or gross weighing unit with a controlled filling spout to deliver consistent bag weights while keeping spillage and dust low. Samirika Group designs rugged open mouth bagging solutions that integrate smoothly with conveyors, bag stitching or heat sealing units, and palletizing systems. These machines help polymer processors, compounders and packaging lines improve throughput, reduce product giveaway, and maintain a neat dispatch area.
Working Principle and Process Flow of Polymer Open Mouth Bagging Machine
The process starts when polymer material is fed from a hopper or silo into a weigh unit through a gravity, belt, screw or vibratory feeder based on product flow behavior. A controller monitors weight signals from load cells and performs coarse and fine feeding to reach the target weight accurately. Once the set weight is achieved, the discharge gate opens and material flows through a filling spout into the open mouth bag. Bag clamping holds the bag firmly, and optional vibration or settling improves fill density. After filling, the bag is released to a conveyor for sealing or stitching, enabling continuous packaging with minimal operator effort.
Types of Polymer Open Mouth Bagging Machines
- Gravity Feed Open Mouth Bagger – Suitable for free-flowing polymer pellets, virgin granules and plastic beads.
- Screw Feed Open Mouth Bagger – Designed for polymer powders, masterbatch powders and additives that need controlled flow.
- Belt Feed Open Mouth Bagger – Works well for irregular granules, regrind flakes and materials needing gentle handling.
- Vibratory Feed Open Mouth Bagger – Ideal when consistent feed control and reduced segregation are required.
- Dual Spout Open Mouth Bagger – Enables higher output lines by running two bagging points in parallel.
Key Features and Specifications of Polymer Open Mouth Bagging Machine
- High accuracy weighing with load cell based control for repeatable bag weights and reduced giveaway.
