How to choose flour powder bagging, metering filling, and sealing packaging? First, consider flowability, dust, and bag type.
For powder packaging of flour, starch, milk powder, seasoning powder, etc., you cannot just look at the 'filling machine'. First, confirm the powder flowability, dust level, metering accuracy, bag structure, and sealing method, then determine the screw, weighing, or volumetric cup filling route.

Real customer question.
I want to package flour, 25 kg per bag. What equipment should I use?
First, determine the packaging route.

Premade pouch filling and sealing route.
Suitable for: Suitable for powders such as flour, starch, milk powder, using premade pouches (three-side seal, back seal, stand-up pouch), requiring automatic bag feeding, filling, and sealing. Advantages: Premade pouches have stable forming, beautiful sealing, suitable for medium to high-speed production, and only need to change molds for different bag types. Limitations: Need to confirm bag material thickness, sealing temperature, and dust-proof design of the filling nozzle; auxiliary feeding is required for poor powder flowability. Not recommended: If the powder has high dust or is prone to dust flying, or if the bag type is non-standard, it is recommended to test a dust-proof solution first. Equipment direction: We can provide a premade pouch filling and sealing machine or a premade pouch filling and sealing packaging machine, combined with a powder granule filling machine for met...
Continuous bag sealing route.
Suitable for: Suitable for sealing already filled bag mouths, or in combination with semi-automatic filling lines, using premade pouches or roll film bags. Advantages: Simple equipment, small footprint, suitable for small batches or switching between multiple bag types. Limitations: Requires manual or semi-automatic bag feeding; sealing speed is limited by manual rhythm; not suitable for high-speed continuous production. Not recommended: If the target capacity exceeds 500 bags per hour, or automatic bag feeding is required, it is recommended to upgrade to the premade pouch filling and sealing route. Equipment direction: We can provide a continuous band bag sealing machine, which can be connected to a conveyor.
Powder granule filling machine + downstream sealing route.
Suitable for: Suitable for powders, granules, and small particle materials, using bottles, jars, pails, or bags for packaging, requiring quantitative filling. Advantages: High metering accuracy, wide adjustment range, suitable for various containers. Limitations: Need to confirm powder flowability, dust, and metering method (screw/weighing/volumetric cup); downstream sealing needs separate configuration. Not recommended: If the powder sticks to walls, clumps, or contains oil, it is recommended to test feeding stability first. Equipment direction: We can provide a powder granule filling machine, and the downstream can be connected to a premade pouch filling and sealing machine or a continuous sealing machine.
Recommended equipment route: Powder metering filling.
Suitable for quantitative filling of powders such as flour, can be configured with screw or weighing metering, high accuracy.
Recommended equipment route: Automatic bag feeding, filling, and sealing.

Recommended equipment route: Bag mouth sealing (if already filled).
Suitable for sealing already filled bags, can be connected to a conveyor.
Recommended equipment route: Conveying and downstream.
Connects filling, sealing, inspection, and case packing, improving overall line efficiency.
Recommended equipment route: Inspection and identification.
Ensure weight compliance, print production date and batch number.

Sample details
Photos and dimensions can first determine container positioning, mold direction, and whether sample testing is needed.
Please provide powder samples or photos, as well as bag samples or bag material specifications. We will determine the metering method and sealing parameters accordingly.The capacity target determines single machine, semi-automatic, or continuous inline configuration, and also affects the quotation range.
Please inform the target capacity (bags per hour) and weight per bag. This determines the machine speed and configuration.On-site conditions affect electrical control, pneumatics, conveyor length, and safety protection configuration.
Please provide on-site space dimensions and power supply conditions, which affect equipment layout and inline solutions.The capacity target determines single machine, semi-automatic, or continuous inline configuration, and also affects the quotation range.
If the information is incomplete, you can first send existing photos, dimensions, and target capacity. We will first determine the route and then supplement the confirmation checklist.Describe the product to be packed, sales scenario, freshness or leakage-prevention target.
Product photos, sample condition, and target marketCommon selection mistakes
Flour packaging has different routes such as premade pouches, roll film bags, and paper bags. Metering includes screw, weighing, and volumetric cup. Not specifying these can lead to incorrect recommendations.
During powder filling, dust may contaminate the sealing area, causing weak seals. Dust-proof design or cleaning before sealing is required.
Flour, starch, milk powder, and seasoning powder have different flowability, density, and oil content, requiring targeted testing.
Food and export projects usually require checkweighing, metal detection, and coding. It is recommended to plan in advance.
Single machines are suitable for sampling and small batches; inline systems are suitable for continuous production. The configuration and quotation differ significantly.
Common questions
The price depends on the equipment type, capacity, automation level, and configuration. It needs to be confirmed based on samples and parameters; a direct quote cannot be provided.
The common capacity of a premade pouch filling and sealing machine is about 1500-3000 bags per hour, depending on the bag type, filling volume, and number of stations.
You can first send photos of the powder and the approximate bag type, and we will determine the direction. However, for a formal quote, it is recommended to provide bag samples.
Common causes are dust contamination of the sealing area or inappropriate sealing temperature. It is recommended to test dust-proof filling nozzles and adjust sealing parameters.
Recommended for food and export projects, it can improve quality traceability and customer acceptance rate.
For small batches or sampling, you can first choose a single machine. After stable orders, upgrade to an inline system. It is recommended to reserve space and interfaces in advance.
