Application:
This Automatic Flour Packing Machine, Also Known as a Vertical Powder Packaging Machine, is specifically designed to provide precision and high-speed packaging of various powders in up to 60 bags/min. It is extensively utilized for cereal flours, wheat flour, tapioca flour, rice flour and seasoning powders, as well as starch baking powders, cocoa powder, protein powder, nutritional powders as well as other small chemical powders. Perfect for food processing facilities as well as powder production lines, this machine guarantees precise, clean and efficient filling of powders and sealing of various types of pouches.
Package Type:
This automatic flour packing machine is compatible with a wide range of powder pouch formats, ensuring stable forming, clean sealing, and high-speed packaging for different market needs. It supports Back Seal (Center Seal) Bags, 3/4 Side Seal Bags, Gusset Bags, etc.
Suitable Products:
This Automatic Flour Packing Machine is specifically designed to provide efficient and precise packaging of a variety of powders from industries like food, chemical industrial, agricultural, and industries. It provides the safest filling and sealing and fast operation for both medium and fine density powders.
- Food & Beverage Powders: Flour & Starch, Seasoning Powders, Milk Powder, Coffee Powder
- Home Care & Daily Chemical Powders: Laundry Detergent, Bleaching Powder, Fragrance Powder, Enzyme Powders
- Industrial & Agricultural Powders: Fertilizer Powder, Construction Additive Powders, Mineral Powders, Fine Industrial Powders
Workflow:
1. Film Rolling Device: The packaging film is automatically unwound from the film roll and guided smoothly into the forming system.
2. Ribbon Printer: Prints production dates, batch numbers, or codes onto the film before the bag is formed.
3. Forming Collar: The flat film is shaped into a tube as it passes through the forming collar.
4. Vertical Sealing Bar: Creates the vertical (back) seal to form the pouch tube.
5. Powder Filling: Powder materials are accurately dispensed into the formed tube through the filling funnel.
6. Servo-Driven Puller Rollers: Pull the film downward steadily to ensure stable bag forming and consistent bag length.
7. Anti-Static Devices: Reduce powder adhesion on the film surface and machine parts.
8. Horizontal Sealer & Cutter: Seals the top and bottom of each bag and cuts them into individual finished pouches.
9. Finished Bag Output: The completed, sealed powder bags are discharged and ready for packing or conveying.

Features:
Auger Screws Feeding Conveyor Ensures stable and continuous powder feeding to the filler. Prevents bridging and keeps the production line running smoothly, especially for fine or sticky powders. | ![]() |
![]() | Dust Collection Device Effectively captures airborne powder during filling to keep the workspace clean. Reduces material loss, protects operators, and improves hygiene for food-grade production. |
Auger Filler for Powder Dosing High-precision servo-driven auger filler guarantees accurate filling weight for flour, starch, milk powder, and other fine powders. Supports different filling volumes with fast adjustment. | ![]() |
![]() | Control Panel User-friendly touch screen interface with clear parameter settings. Allows operators to control speed, bag length, filling weight, and sealing temperature easily and efficiently. |
Form Structure Forms the flat film into a neat and consistent pouch shape. Ensures stable bag forming for various bag sizes with smooth film tracking and high packaging quality. | ![]() |
![]() | Sealing Structure Uses reliable vertical and horizontal sealing bars for strong, leak-proof seals. Ensures beautiful bag appearance and maintains the freshness and flowability of powder products. |
Anti-Static Devices Reduces powder adhesion on the film surface and machine parts. Keeps bag sealing clean and prevents inaccurate forming caused by static electricity-ideal for flour and lightweight powders. | ![]() |
