Nutracap Holdings LLC, a supplements manufacturer in the United States, required a higher-capacity packaging system for vitamin powder.
The product was moisture-sensitive and dust-prone, creating challenges in powder transfer, dosing consistency, seal cleanliness, and continuous high-speed production.
EIXPACK supplied a customized 10-lane vitamin powder stick pack packaging machine designed around automatic feeding, auger dosing, film alignment, bag forming, sealing, date coding, cutting, and finished-pack discharge.
The project target was to increase production capacity to as much as 400 packs per minute while reducing manual handling, filling variation, powder leakage, and product trapping in the sealing area.
The project demonstrates how a multi-lane powder packaging system can help supplement manufacturers move from labor-intensive packaging toward more stable, scalable, and controlled production.
The existing production capacity could not efficiently support growing order volumes. Low packaging output could extend production schedules, delay deliveries, and restrict the customer’s ability to accept larger orders.
Manual powder feeding, dosing, pack handling, and production supervision required considerable labor input. As output increased, adding more operators would raise the cost per finished pack.
Unstable powder flow and manual intervention could lead to variation between stick packs. Underweight packs create quality risks, while overfilling results in unnecessary giveaway of valuable vitamin powder.
Fine airborne powder could enter the sealing area during filling. Powder trapped between the film layers may weaken the seal, affect package appearance, or increase the number of rejected packs.
Vitamin powder may absorb moisture during handling or temporary exposure. Moisture absorption can cause caking, unstable feeding, buildup around product-contact parts, and interrupted dosing.
Dust and unstable filling could cause powder to escape around the dosing and sealing areas. This increased cleaning requirements, material loss, and production-floor contamination.
The project was developed around the following production objectives:
EIXPACK provided a customized 10-lane vitamin powder stick pack packaging machine as the core of the project.
The machine combines multiple packaging functions within one integrated platform, allowing ten stick pack lanes to perform synchronized dosing, forming, sealing, coding, cutting, and discharge.
For buyers evaluating similar moisture-sensitive and dust-prone formulations, the vitamin powder stick pack packaging machine solution explains how product behavior, target dose, film selection, dust management, and production capacity should be considered together.
The automatic feeding system transfers vitamin powder into the dosing hopper and reduces repeated manual loading. More consistent powder supply helps prevent interruptions caused by an insufficient hopper level and supports continuous operation across all ten lanes.
For this project, automatic feeding was important because a production target of 400 packs per minute would create a much higher powder demand than a manually loaded system could reliably maintain.
The auger dosing system controls powder discharge through a rotating screw. The auger specification and operating parameters can be matched to the vitamin powder’s bulk density, flowability, dust level, and target filling weight.
Compared with less controlled volumetric filling methods, auger dosing provides more repeatable powder delivery and helps reduce both overfilling and underweight packs. It is especially suitable for fine supplement powders that do not flow consistently under gravity alone.
The automatic film alignment system monitors the rollstock position and makes corrective adjustments when the film begins to move away from the intended path.
Stable film tracking helps keep the printed design, bag edges, longitudinal seal, cross seal, and cutting position aligned. This is particularly important on a 10-lane system because small film deviations can affect multiple packs simultaneously.
The rollstock film is divided and guided into ten packaging lanes. Each lane forms a narrow stick pack around its corresponding forming section.
The forming structure was selected to produce the customer’s round-corner stick pack format while maintaining consistent bag width and shape across all lanes. Proper forming also reduces wrinkles that could interfere with sealing.
The forming and sealing system creates the longitudinal and transverse seals required to close each stick pack. Sealing temperature, pressure, and contact time must be matched to the selected film structure and actual production speed.
For dust-prone vitamin powder, the dosing timing and sealing timing must also be coordinated. This helps reduce the possibility of airborne powder remaining between the film layers when the sealing jaws close.
The date coding system prints production dates, expiration dates, batch numbers, or other traceability information onto the packaging film.
Coding is integrated into the packaging sequence so that each stick pack receives the required production information before final cutting and discharge. The coding method should be selected according to the packaging material, print content, line speed, and required print durability.
The feeding, dosing, film movement, sealing, coding, and cutting sections operate as one coordinated system. Production parameters can be adjusted according to powder behavior, bag size, film response, and target output.
This integrated architecture is more suitable for high-speed vitamin powder production than combining multiple disconnected machines. It also creates a clearer path for future counting, inspection, cartoning, or case-packing integration.
The core packaging platform is based on EIXPACK’s multi-lane powder stick pack machine, which is intended for supplement, nutraceutical, pharmaceutical-related, food powder, and contract manufacturing applications.
EIXPACK can support this type of project through the complete equipment-selection and implementation process.
The engineering team reviews the product, target filling weight, required output, pack size, film structure, available production space, electrical conditions, and future automation requirements.
Actual vitamin powder and film samples can be evaluated to identify flowability, dust behavior, moisture sensitivity, dosing stability, sealing risk, and required machine adjustments.
The number of lanes, auger structure, feeding method, forming components, coding method, and optional dust-management features can be selected according to the project requirements.
A proposed layout can be prepared according to the customer’s factory space, operator access, material flow, cleaning access, and potential downstream equipment.
Before shipment, the machine can be tested using agreed materials and packaging conditions. Key functions such as feeding, filling, film movement, sealing, coding, cutting, and output can be reviewed.
Installation and commissioning support can be provided remotely or on site, depending on the project agreement and destination requirements.
Operators can receive guidance on machine startup, parameter adjustment, product changeover, cleaning, routine inspection, troubleshooting, and shutdown procedures.
Maintenance guidance and recommended spare-parts lists can be provided to help the customer plan preventive maintenance and reduce unexpected downtime.
The packaging line can be evaluated for future integration with checkweighing, inspection, counting, cartoning, conveying, or case-packing equipment.
“The 10-lane vitamin powder stick pack system was designed around our need for higher production capacity and more consistent filling. The automatic feeding and auger dosing functions reduced the amount of repetitive manual handling, while the film alignment and sealing sections improved overall pack consistency. The solution gives our team a clearer path toward reaching higher output with fewer operators.”

The machine is designed for vitamin powder and can also be evaluated for similar fine powders such as mineral blends, electrolyte powder, collagen powder, functional beverage powder, and other supplement formulations. Final suitability depends on powder flowability, density, moisture sensitivity, filling weight, and sample testing.
The project target is up to 400 packs per minute using a 10-lane configuration. The confirmed production speed depends on the actual powder, filling weight, stick pack size, film structure, sealing conditions, coding requirements, and stable operating parameters.
Auger dosing controls powder discharge through screw rotation and is commonly used for fine powders that do not flow consistently under gravity. The auger, hopper, and filling outlet should be selected according to the actual powder sample.
Product trapping is reduced by coordinating powder transfer, dosing timing, filling position, film movement, and sealing timing. Optional dust-control measures may also be evaluated when the product generates significant airborne powder.
Bag length can normally be adjusted within the machine’s supported range. Different bag widths may require corresponding forming components. The available size range must be confirmed according to the selected machine, filling weight, film, and sealing structure.
