The SUK granule packing machine combines automatic product feeding, multi-head weighing and vertical form-fill-seal packaging for snacks, nuts, seeds, grains and other dry, free-flowing products. It helps factories produce consistent pillow or gusset bags with an automated weighing, filling and sealing workflow.
The SUK granule packing machine combines automatic product feeding, multi-head weighing and vertical form-fill-seal packaging for dry, free-flowing products. It is suitable for snacks, nuts, seeds, grains and other granular materials that need repeatable weight control and sealed bags for factory production.
For a correct model recommendation, SUK reviews the product type, target weight, bag width, bag length, film structure, expected output and available factory conditions before confirming the final configuration.

Granular products are not all the same. Potato chips are light and fragile, peanuts can vary in size and shape, while grains and seeds may flow differently through the weighing system. A practical granule packaging machine therefore needs more than a bag former. It needs a suitable feeding arrangement, a weighing system matched to the material and a sealing system that can produce consistent bags at the required speed.
The SUK system is designed for this production workflow. Product is transferred to the weighing unit, the selected weight is released to the VFFS machine, film is formed into a bag, and the filled bag is sealed and discharged. The result is a continuous packaging process that reduces repetitive manual weighing and helps factories maintain a consistent pack presentation.
The machine can be configured for a range of dry, free-flowing materials, including:
Typical bag formats include pillow bags and gusset bags. The final format depends on the film width, product characteristics, bag dimensions and sealing requirements. Product samples and target packaging drawings should be supplied before the machine configuration is finalized.
The product is fed from the infeed system to the weighing unit. For snack foods, nuts and other products with different particle sizes, the feeding system must be adjusted to avoid excessive breakage, bridging or uneven distribution. The infeed design and hopper arrangement can be reviewed against the product sample and required output.
The multi-head weigher combines product portions from several weighing hoppers to reach the target weight. This approach is useful for products such as snacks, nuts, seeds and grains because the weighing combination can respond to natural variation in individual pieces. The actual accuracy and output depend on the product, target weight, feeding stability and operating conditions.
After weighing, the measured product is released into the forming tube. The vertical packaging unit forms the film, fills the bag and completes the sealing and cutting cycle. Pillow bags are commonly used for high-throughput snack and grain products. Gusset bags can provide a different shelf presentation and additional standing volume when the film and machine configuration support the format.
Finished bags can be discharged to a collection conveyor, inspection point or secondary packaging line. If the factory needs cartoning, checkweighing, metal detection or case packing, the granule packing machine can be reviewed as part of a wider packaging line rather than treated as an isolated machine.
The following figures are based on the existing SUK vertical weighing and packaging machine configuration. They are reference specifications for initial project discussion, not a substitute for final engineering confirmation.
| Parameter | Reference specification |
|---|---|
| Model | SKL-420 |
| Compatible materials | Granules, snacks, seeds and grains |
| Weighing method | Multi-head weigher or linear weigher, according to configuration |
| Packing speed | 30–70 bags/min, depending on material and pack conditions |
| Bag length | 80–300 mm |
| Bag width | 60–200 mm |
| Accuracy range | ±0.1–1.5 g, depending on material, target weight and operating conditions |
| Maximum film width | 420 mm |
| Bag types | Pillow bag, gusset bag and punching bag, according to configuration |
| Power supply | 220V/380V, 50Hz; approximately 3.5 kW reference configuration |
| Air consumption | 0.6 MPa, approximately 0.4 m³/min reference configuration |
| Machine weight | Approximately 1,200 kg reference configuration |
The final machine size, power, weighing head arrangement, film path and bag range should be confirmed from the customer's product samples and packaging requirements. This is particularly important when a project combines fragile snacks, mixed nuts or products with a wide particle-size range.
A granule packaging project usually involves several decisions at the same time: how to weigh the product, how to protect it during feeding, which bag format to use and how to connect the machine to the rest of the factory line. SUK can evaluate these requirements together instead of selecting the VFFS machine by speed alone.
The supplied machine images show the type of integrated system used for granule applications: an elevated weighing platform, product feeding equipment, a vertical bagging unit and factory-ready discharge. The actual layout can be adapted to the available space, access requirements and downstream equipment.
For factories comparing a vertical weighing system with a premade pouch solution, the bag supply method is the main difference. A vertical granule packing machine forms bags from roll film, while a premade pouch machine fills and seals bags that have already been manufactured. The right choice depends on branding, pouch structure, changeover needs, bag presentation and production planning.
To recommend a practical granule packing machine configuration, send the following information:
A sample-based review is important because nuts, chips, grains and seeds can behave differently even when they use the same bag style. It also helps SUK avoid recommending a weighing range or film width that does not match the actual production target.
Send your product, target weight, bag drawing or sample image and expected speed to SUK. The engineering team can then review the suitable weighing method, VFFS model, bag format and line configuration for your factory.

It can be configured for snacks, nuts, seeds, grains, beans and other suitable dry free-flowing products. Product testing is recommended because particle size, density, fragility and surface characteristics affect feeding and weighing.
The SKL-420 reference configuration can support pillow bags and gusset bags when the film width, forming parts and sealing arrangement are suitable. The final bag format should be confirmed with a bag drawing or sample.
A VFFS machine forms bags from roll film before filling and sealing. A premade pouch machine uses bags that have already been made. The choice depends on bag appearance, film supply, changeover requirements and the factory's packaging workflow.
Yes. The machine can be reviewed together with feeding, conveying, inspection, cartoning or case-packing equipment. The required interfaces should be defined during the line-planning stage.
SUK needs the product type, product sample or images, target weight, bag size, film information, desired output and factory conditions. These details are used to confirm the configuration rather than relying on a generic speed claim.
