Kenwei Revolutionizes China's Food Packaging with High-Speed Combination Weighing Systems | Vertical Packaging Machine Solution
With the rapid expansion of China's food industry, the demand for high-performance vertical packaging machines has grown dramatically. In 2005, leading manufacturers like BAOPACK and Songchuan introduced the first domestically produced 10–14 head combination scale weighing and packaging systems, addressing the growing need for high speed, high precision, and full automation in the food packaging process. These advancements triggered a surge in market demand and laid the foundation for creating top-tier brands in China’s food packaging equipment sector.
During BAOPACK’s early years, its vertical packaging machines faced limitations when sold as standalone units. Since food packaging is inseparable from accurate weighing, the need for a matching weighing system became a driving force for innovation. As Mr. Zhou from BAOPACK reflected:
“In the beginning, vertical packaging machines were often paired with manual weighing. Workers would weigh products manually, load them onto conveyors, and feed them into the packaging machines. This method required more labor, resulted in disorganized workflows, and led to machine instability due to inconsistent manual operations.”
Subsequently, cup-type fillers and basic electronic scales were introduced as interim solutions. While they improved efficiency slightly, they presented several drawbacks:
-
Limited applicability: Suitable only for uniform, small-particle products.
-
High weighing error: Even products like pistachios had errors exceeding 6g.
-
Low accuracy and speed: These tools could not meet the rising standards of modern food manufacturers.
The introduction of imported combination weighers promised a solution but fell short in practice—high costs and expensive maintenance services made them inaccessible to many domestic food companies.
That’s where Guangdong Kenwei Intellectualized Machinery Co., Ltd. made a significant breakthrough. Kenwei adopted advanced electronic components and developed a locally manufactured combination weigher system that matched or exceeded the performance of international brands—at a price point accessible to Chinese food producers. This game-changing innovation removed the entry barrier to high-end weighing technology for small and medium-sized enterprises, making automated, high-precision weighing available to a broader market.
Key Advantages of Kenwei’s Combination Weighers:
-
Wide application scope: Suitable for candies, seeds, frozen foods, jelly, puffed snacks, pet food, plastic parts, and hardware items.
-
High precision & speed: Reduces weighing error and increases packaging throughput.
-
Cost-efficiency: Competitive pricing and localized service significantly reduce long-term operational costs.
-
Labor reduction: Automated systems decrease workforce dependency and improve production line efficiency.
-
Resource savings: Lower material waste and enhanced equipment management.
Kenwei’s quantitative combination weighing and vertical packaging systems have triggered a nationwide transformation across food manufacturing sectors. By integrating smart automation, manufacturers are achieving greater output with fewer resources—ushering in a new era of intelligent packaging in China.

What is the difference between a multi-head weigher and a linear weigher?
Multi-head Weigher: Ideal for high-speed and high-precision weighing of products with irregular shapes or varying sizes. It provides multiple weighings in parallel for faster processing.
Linear Weigher: It is suitable for powder and granule. It is typically slower than a multi-head weigher but is effective for certain types of applications that require more continuous flow or controlled weighing.
