Open Mouth Baggers

Open Mouth Baggers are a type of bagging scale that fills bags, boxes, or totes with loose product. They are used in a variety of industries such as food, agriculture, chemical, and bulk pharmaceutical. These machines provide efficient and accurate filling, which helps to reduce costs and increase productivity.

There are several key features and benefits of Open Mouth Baggers:

  • Automation: Open mouth baggers are available in auto and semi-auto configurations depending on the application, but can always fill and close bags at a much faster rate than manual labor. They are usually meant to be paired with bag placers or sealing equipment (can be sewing, heat-sealed, etc.) so processes can be scaled as the company does.
  • Accuracy: Open Mouth Baggers are designed to provide accurate filling and weight control, ensuring that each bag contains the correct amount of product. This helps to reduce waste and deviations in quality.
  • Customization: Open Mouth Baggers can be customized to meet the specific requirements of different industries and products. They can be fitted with different filling systems, such as gravity, volumetric, or auger-based systems, to ensure the best results for each application.
  • Versatility: Open Mouth Baggers are capable of handling a wide range of products, from powders and granules to liquids and pastes. They can also be used with different types of bags, including woven, laminated, and paper bags.
  • Ease of use: Open Mouth Baggers are designed to be user-friendly, with intuitive controls and easy-to-read displays. This makes it simple for operators to set up and use the machine, reducing the risk of errors and increasing efficiency.
  • Cost-effectiveness: Open Mouth Baggers can help to reduce costs by increasing productivity and reducing waste. They are also designed to be low-maintenance, reducing the need for frequent repairs and replacements.

  • Flexibility: Open Bag Fillers can accommodate a wide range of bag sizes and materials, making them suitable for a variety of products and applications.
  • Ease of use: Open Bag Fillers are simple to operate and maintain, reducing the risk of operator error and increasing efficiency.
  • Speed: Open Bag Fillers are capable of filling bags at a faster rate than manual labor, reducing the time and resources required to complete the packaging process.
  • Accuracy: Open Bag Fillers are designed to provide accurate filling and weight control, ensuring that each bag contains the correct amount of product and reducing waste.
  • Cost-effectiveness: Open Bag Fillers are often less expensive than valve bag fillers.


  • Dust Control: Open Bag Fillers can generate dust during the filling process, which can be a problem in certain applications. We have special models for this issue as well as a variety of dust collection systems, so this is application-dependent.
  • Product Exposure: Open Bag Fillers can expose the product to the environment, increasing the risk of contamination.
  • Bag Closure: Open Bag Fillers don’t typically provide a means of sealing the bags, which must be done separately.

Things to consider when choosing between valve and open-bags

  • Filling Method: Open mouth bags are ideal for products that are filled using gravity or volumetric filling systems, as these methods require the bag to be open during filling. Valve Bags, on the other hand, are typically filled using pressure or vacuum systems and the valve is used to discharge the product into the bag.
  • Product Characteristics: Open mouth bags are often used for products that are hygroscopic, or absorb moisture from the air, as they allow for the bag to be sealed after filling while still allowing air to escape. Valve Bags, on the other hand, are often used for products that are free-flowing and do not absorb moisture, as the valve can be used to discharge the product into the bag without exposing it to the air.
  • Dust Control: Open mouth bags are used for products that generate dust during filling, as the bag can be sealed after filling to reduce dust emissions. Valve Bags are not typically used for products that generate dust, as the valve can become clogged with product and reduce the efficiency of the filling process.
  • Packaging Line Layout: Open mouth bags can be used in packaging lines where the bags are filled and then moved to a separate area for closure, while Valve Bags are often used in packaging lines where the bags are filled and closed in a continuous process.
  • Initial Cost: Open Mouth Baggers generally cost less up-front, but will be more if they require another piece of equipment for sealing and you don’t have that handled.
  • Operating Cost: Open mouth bags are typically less expensive than Valve Bags, as they do not require a valve to be integrated into the bag.
