Introduction to Polymer Open Mouth Packing Machine
A polymer open mouth packing machine is a specialized bagging solution designed to weigh, fill, and discharge polymer granules or pellets into open mouth bags with consistent accuracy. These machines are widely used in polymer processing and compounding plants where clean filling, stable bag weights, and reliable throughput are essential for dispatch-ready packaging. Samirika Group manufactures heavy-duty open mouth packing systems that support dependable operation in continuous production environments. With precise weighing control, robust product contact construction, and integration-ready design, the machine helps reduce spillage, improve bag presentation, and maintain production discipline across shifts.
Working Principle and Process Flow of Polymer Open Mouth Packing Machine
The working flow begins with polymer granules being fed from a silo or hopper into a controlled weighing unit using gravity, belt, or vibratory feeding based on the material’s behavior. A microprocessor-based controller monitors weight signals from load cells and adjusts feed speed to achieve stable target weights. Once the set weight is reached, the discharge gate opens and releases the measured quantity into an open mouth bag held by a bag clamp or spout. The filled bag is then transferred via conveyor for stitching, sealing, or further handling. This controlled process supports repeatable bag weights and smoother packaging line performance.
Types of Polymer Open Mouth Packing Machines
- Gravity Feed Open Mouth Packers – Suitable for free-flowing polymer granules and pellets with stable discharge.
- Vibratory Feed Open Mouth Packers – Designed for controlled flow, gentle handling, and reduced material bounce.
- Belt Feed Open Mouth Packers – Ideal for consistent feeding of larger pellets or blends requiring steady metering.
- Net Weigh Open Mouth Systems – Separate weigh hopper improves accuracy and reduces giveaway in bulk packing.
- Automatic Bag Clamping Packers – Support faster cycles and consistent bag placement for higher throughput lines.
Key Features and Specifications of Polymer Open Mouth Packing Machine

Applications of Polymer Open Mouth Packing Machine
- Polymer Granules and Pellets – Packing of PP, PE, HDPE, LDPE, and other granulated resin materials into industrial bags for distribution.
- Masterbatch and Compound Packaging – Weighing and bagging of color masterbatch, additive masterbatch, and compounded pellets with consistent outputs.
- Recycled Polymer Processing – Bagging of recycled pellets and reprocessed granules where controlled filling reduces spill and improves bag presentation.
- Industrial Raw Material Dispatch – Packing of resin blends, polymer additives in pellet form, and bulk granulated materials for supply chain movement.
Benefits of Using Polymer Open Mouth Packing Machine
- Consistent Bag Weights – Accurate weighing reduces underfill and overfill, helping maintain packaging compliance and dispatch reliability.
- Cleaner Packing Operation – Controlled discharge and stable bag clamping reduce spillage and improve workplace hygiene.
- Higher Packaging Productivity – Faster cycle control supports improved throughput compared to manual or semi-controlled filling methods.
- Better Bag Presentation – Stable filling and controlled flow support neat bag shape and reduced product loss during bag handling.
