According to the latest report by Allied Market Research, the global protein supplement market was valued at USD 23.9 billion in 2021 and is projected to reach USD 50.7 billion by 2031, growing at a CAGR of 7.8% from 2022 to 2031. Among all product types, powdered protein supplements dominate the market due to their high digestibility, versatility, and consumer preference.
The growing demand for protein supplements in the United States has driven an urgent need for efficient and hygienic packaging production lines. Manufacturers of health and nutrition products are now seeking customized, powder bottle filling line that ensure accuracy, consistency, and compliance with food safety standards.
To meet this evolving demand, Ruidapacking provides tailor-made powder filling line solutions.
A New Partnership Born at the Shanghai CPHI
During the Jun 24-26 Shanghai CPHI, Simon, the purchasing manager of a U.S.-based nutritional supplement company, met Owen, a representative from Ruidapacking. Simon shared details about a new project that initially considered using a 既製ポーチ包装機 to packing protein powder.
However, after in-depth discussions, Owen identified a critical limitation — the client’s factory had a height of only 3.1 meters, while the doypack pouch packaging machine required 3.3 meters. Despite the height constraint, the factory space was large and suitable for a horizontal layout.
Owen recommended a protein powder filling packing line as an alternative solution. This case effectively addressed the height issue while maintaining production efficiency and quality. After three months of repeated consultation and technical discussions, both sides reached a cooperation agreement and finalized a customized solution for the American customer.
Customized Powder Filling Line for Protein Powder Bottling
The powder filling line is designed to accurately fill various powders into bottles of different sizes with a filling accuracy of ±1%. The entire line includes:
- Linear Screw Feeder
- 粉末充填機
- Cap Feeding and Capping Machine
- Round Bottle Positioning Labeling Machine
- Bottom Coding Machine (UV Type)
- Shrink Sleeve Labeling Machine
Each machine is carefully selected and integrated to meet the customer’s production goals for protein powder packaging.
Linear Auger Feeder
Considering the flow characteristics of protein powder, Owen recommended a linear screw feeder. This system uses rotation counts to control the powder feed, ensuring precise dispensing with an accuracy of ±1%.
Alternatively, customers can choose volumetric or weighing-type filling systems depending on the product and accuracy requirements, real-time monitoring, automatic rejection of inaccurate fills.
粉末充填機
Since the customer uses two different bottle sizes, we customized the filling nozzles to minimize powder spillage onto the conveyor. This not only ensures compliance with food hygiene standards but also reduces material waste and shortens cleaning time, improving overall efficiency.
キャッピングマシン
Each protein powder jar includes a measuring scoop, which is placed before capping. Because the bottle caps are large, equipped the line with a grab-type capping machine. This system ensures a high capping success rate and stable performance, even when the bottles are filled to near capacity.
Round Bottle Positioning Labeling Machine
The client’s bottles have a unique shape — narrower at the top and wider at the bottom. A standard labeling machine would cause wrinkles or misalignment. To solve this, Owen recommended a positioning labeler, which precisely adjusts to each bottle’s contour.
Although slightly slower than common automatic labelers, this system guarantees flawless label application and enhances product presentation and brand image.
UV Coding Machine
To ensure traceability and compliance, the powder bottling filling packing line integrates a UV laser coding machine. It can print on both the bottle caps and bottoms without any consumables. The UV coding process offers high precision, permanence, and zero environmental waste, making it an eco-friendly solution.
Shrink Sleeve Labeling Machine
For added safety and tamper-evident protection, the final stage of the line features a shrink sleeve labeling machine. It seals the cap and bottle neck area, assuring consumers that each product is factory-sealed and untouched.
Performance Testing and On-Site Acceptance
After one month of manufacturing, Ruidapacking completed the production and conducted strict pre-shipment tests. Owen invited Simon to the factory for a factory acceptance test (FAT) with his two bottle sizes.
During the test, the line ran smoothly and consistently, meeting all key performance criteria. However, a few minor issues were identified — such as inconsistent scoop placement and the sleeve shrink labeler lacking a door interlock.
The engineering team immediately addressed these concerns through technical modifications. After adjustments, Simon expressed his satisfaction with the overall quality and performance of the equipment.
Dedicated to Customer-Oriented Innovation
This successful cooperation reflects Ruidapacking’s commitment to providing flexible, customer-focused solutions for the global market. By understanding each client’s specific factory layout, production goals, and material characteristics, we can provide turnkey solution that optimize both efficiency and compliance.
Powder filling packing line are widely used in nutrition, food, pharmaceutical, and chemical industries, offering reliable automation, hygienic design, and precision control.
