Zhongjing Dali Pharmaceutical needed a more stable and higher-capacity packaging solution for food supplement powder stick packs. The customer’s existing equipment could no longer support new order demand, and production was affected by unstable machine performance, powder trapping during sealing, and inconsistent filling accuracy.
To solve these issues, EIXPACK provided a customized food-supplement-powder-stick-pack-packaging-machines Food Supplement Powder Stick Pack Packaging Machines solution designed for dust-prone and moisture-sensitive powder products.
The project focused on increasing output toward 400 packs per minute, improving filling accuracy to ±0.5g, and reducing powder trapping through better powder handling, dosing, forming, sealing, cutting, inspection, and finished product output integration.
The customer’s existing machine could not maintain stable operation during continuous production. This created production interruptions, reduced delivery reliability, and increased operator workload.
New order demand required a higher and more stable packaging output. The previous equipment could not support the target production capacity, limiting the customer’s ability to accept larger or more urgent orders.
Food supplement powder is dust-prone and can easily enter the sealing area. Powder trapping may lead to weak seals, poor package appearance, higher rejection rates, and potential product leakage.
Inconsistent filling accuracy can cause underfilled or overfilled packages. Underfilling creates quality and compliance risks, while overfilling increases product giveaway and long-term material cost.
The packaged product is moisture-sensitive, so sealing quality, film handling, and clean powder transfer are critical. Poor sealing may expose the powder to moisture and affect product quality.
The project was designed to help Zhongjing Dali Pharmaceutical achieve the following goals:
EIXPACK supplied a customized food supplement powder stick pack packaging system for Zhongjing Dali Pharmaceutical.
The solution was built around the customer’s core requirements: higher output, better filling accuracy, reduced powder trapping, and stable continuous production for dust-prone and moisture-sensitive powder.
The system can include the following functional modules, depending on the final product, bag size, film material, and production target:
The automatic feeding system transfers powder into the dosing unit with reduced manual handling. For dust-prone supplement powder, this helps improve production cleanliness, reduce operator exposure to powder dust, and support more stable upstream feeding.
For food supplement powder, the dosing system is a key module for filling accuracy. Depending on powder flowability, density, and dosage range, the machine can be configured with an auger dosing system or another suitable powder filling structure. The goal is to improve filling consistency and reduce both underfilling and overfilling.
The forming and sealing system forms the stick pack shape and seals the package. For this project, the packaging format was round-corner stick packs with easy-tear notch. A stable sealing system helps reduce weak seals, improve package appearance, and protect moisture-sensitive powder from air and humidity.
Because the product is dust-prone, powder control around the filling and sealing area is important. The system can be configured with dust reduction and extraction-related structures to help prevent powder from contaminating the seal area and causing trapped material.
The laser coding system can print production date, batch number, or traceability information on the stick pack. This supports pharmaceutical and supplement production management, batch identification, and market circulation requirements.
The conveyor system transfers finished stick packs from the packing machine to the next handling or collection stage. It helps reduce manual transfer, improve production continuity, and prepare the line for possible downstream automation.
This solution works because it was designed around the actual behavior of food supplement powder.
Dust-prone powder requires better feeding control, sealing area protection, and cleaner transfer. Moisture-sensitive powder requires stable sealing and consistent package integrity.
The target of ±0.5g filling accuracy requires a suitable powder dosing system and stable machine control.
For Zhongjing Dali Pharmaceutical, the project did not only focus on speed. It also addressed the production problems that directly affected business results:
unstable operation, inability to meet new order demand, trapped powder, and inaccurate filling. By integrating feeding, dosing, forming, sealing, coding, cutting, inspection, conveying, and finished product output, the system creates a more reliable production flow for pharmaceutical and supplement powder stick packs.
For this type of powder stick pack packaging project, EIXPACK can provide project support throughout the complete delivery cycle, including:
The new food supplement powder stick pack packaging system helped us improve production stability and better support our new order demand. The machine structure is more suitable for our powder product, especially in terms of filling accuracy, sealing quality, and reducing powder trapping. The technical support during the project also helped our operators understand daily operation and maintenance more clearly.”

EIXPACK can support similar food supplement and pharmaceutical powder stick pack projects with the following capabilities:
They can handle powder products such as food supplement powder, pharmaceutical powder, collagen powder, protein powder, vitamin powder, probiotic powder, electrolyte powder, and other similar dry powder formulas. Final machine configuration depends on powder flowability, dust level, dosage, and packaging requirements.
Yes. Stick pack length, width, sealing style, cutting style, round-corner design, and easy-tear notch can be customized according to the customer’s package design and production requirements.
For many supplement powders, an auger dosing system is commonly used because it offers better control for fine powder filling. The final dosing system should be selected after evaluating powder flowability, bulk density, target weight, and required accuracy.
The system can reduce powder trapping through controlled powder feeding, suitable dosing structure, stable film forming, sealing area protection, dust control design, and proper synchronization between filling and sealing.
Yes. The system can be configured with a laser coding system or other suitable coding equipment to print production date, batch number, and traceability information on the stick pack.
Before quotation, the customer should provide product type, powder characteristics, target filling weight, required speed, stick pack size, packaging film information, coding requirements, workshop layout, and whether downstream automation is needed.
Yes. The finished product output system can be planned for future integration with cartoning machines, counting systems, conveyors, checkweighers, or other secondary packaging equipment.
This solution is suitable for medium to large production, especially when the customer needs higher output, better filling accuracy, lower labor dependency, and more stable continuous production. Entry-level or lower-speed configurations can also be customized according to actual production needs.
