Ruida Packing recently welcomed clients from Taiwan for an on-site visit and technical discussion. The clients are a Taiwan-based nutrition brand manufacturer, primarily producing protein powder. With the rapid growth of online shopping and health supplement demand, the client planned to upgrade their stick packing line with a standing pouch format, focusing on three core challenges: how to achieve high filling accuracy for powdered products, how to ensure consistent sealing quality at higher speeds, and long screw feeding design prevent powder overflow.
Our VFFS machine can package a wide range of solid, пудра, и жидкие продукты. Например, кофейный порошок, протеиновый порошок, специи, and seasoning blends for solid and powder materials, as well as liquid products like mouthwash, hand sanitizer, single-serve shampoo, and liquid condiments (например, soy sauce or cooking oil).
The visit was hosted by Sales Executive Mary, who accompanied the clients throughout the workshop and introduced Ruida Packing’s standing-type stick packing machine tailored for fine powder applications.

Based on the client’s product characteristics, Mary directed their attention to the servo-driven system. Unlike conventional machines that rely on mechanical clutches or variable-frequency drives, this model uses independent servo motors for film feeding, material feeding, и резка. The servo system provides three key advantages: precise motion control at startup and stop, real-time speed adjustment without mechanical wear, and significantly lower noise during continuous operation.
For protein powder, it prone to be dusting, the client placed the highest priority on filling accuracy. Mary introduced to them the machine’s long-screw precision filling system. The extended auger design allows powder to be conveyed downward over a longer distance before discharge, which minimizes air entrapment and improves volumetric consistency. The auger is directly coupled to a dedicated servo motor, enabling fill weight adjustments in increments of less than 0.2 grams. Во время демонстрации, the machine maintained a filling accuracy of ±0.2g for whey protein powder at a speed of 45 мешков в минуту.

The client also raised concerns about sealing integrity when switching between different materials—from fine protein powder to more granular coffee powder. Mary explained that the heat sealing system uses PID-controlled heating plates, which offer fast heat-up times and maintain temperature stability within ±0.1°C. This ensures consistent and reliable seal quality across production runs.
The forming tube is precision-machined using CNC (Computer Numerical Control) технологии, where a computer-guided cutting tool shapes the metal with extreme accuracy. This guarantees high precision and consistency in the tube geometry. To change the bag size or shape (например, three-side seal, four-side seal, заднее уплотнение, or side seal), a custom-formed tube must be ordered. If only changing the product, for example from coffee powder to protein powder, the same forming tube can be used without modification.
Another practical benefit highlighted was the standing pouch forming system. The sachet packaging machine can produce палочки that stand upright on shelves, which is a significant advantage for retail display and consumer convenience. The film tracking is servo-controlled, ensuring that print registration and pouch alignment remain stable even when running at variable speeds during startup or material roll changes.
Ruida also provide stick packaging machine for liquids like shampoo, духи, mouthwash etc.
На протяжении всего визита, the client raised detailed questions about powder dust control, cleaning access for the auger and sealing area, and energy consumption compared to traditional clutch-type machines. Mary answered each by linking specific servo-driven and aluminum alloy features to the client’s daily production scenarios.
The client was particularly impressed by how the long-screw servo system improve feeding accuracy and reduce sealing contamination while improving fill accuracy, delivering a higher pass rate – especially valuable for expensive ingredients like collagen peptides.
The mechanism behind dust reduction is as follows: as the powder moves down along the screw’s helical structure, the screw pulls back slightly after each fill. This prevents excess powder being added and also avoids extra dust from rubbing against the seal area. If the seal area becomes contaminated with excess powder, sealing efficiency and seal quality will be compromised.
Благодаря этому визиту на место, the client gained a clear understanding of how Ruida Packing’s servo-driven standing vertical form fill seal machine can solve filling accuracy, sealing consistency, and changeover flexibility challenges in one integrated system. Для упаковки Руиды, the visit reinforced its commitment to providing intelligent, precise, and easy-to-clean packaging solutions for the nutrition, functional food, and instant beverage industries.
