【Corrface Machine Exploration-MING WEI GROUP】MAX-350S Corrugated Line Machine: Empowering Enterprises to Capture Market Leadership Through Strategic Differentiation.

March,13, 2026


In the fiercely competitive market, how can packaging companies that focus on niche sectors overcome order acquisition challenges and carve out a broader market space? In this episode, Corrface visits Dongguan Yuying Paper Industry to explore how Yuying successfully expanded its market by specializing in single-face orders!

 

Yuying concentrates on producing differentiated products within traditional markets,  primarily handling complex single-face orders in the color box category using G-flute and F-flute corrugation. Their order lengths range from tens to tens of thousands of meters, achieving a monthly revenue of 20 million RMB. As gift box orders demand stringent performance from single-facer machines, Yuying selected Minwei Group’s  flagship corrugator line—the Hanjiang series MAX-350S corrugated lineafter evaluating efficiency, quality, and stability.

 


When asked why they chose Minwei’s equipment for single-face production, Yuyings manager explained, Minweis proprietary technology reduces corrugation marks on paperboard without compromising bursting resistance unlike traditional machines. Additionally, Minweis equipment maintains stable quality even at 175 meters per minute, ensuring smooth surfaces with minimal indentationcritical for gift box orders requiring flatness. In terms of rigidity and finish, Corrface then showcased freshly produced G-flute paper from Minweis line, the surface was flawlessly smooth with no black lines or dents, and the flute curvature was impeccable. Yuyings double-G corrugated boards offer higher rigidity than four-layer boards while being lighter, reducing transportation costs and lowering fixed costs per square meter to boost profitability.

 

Another advantage of Minwei’s equipment lies in its user-friendly operation and flexibility. Yuying demonstrated switching from G-flute to F-flute production. Disconnect the lifting platform, connect air pipes, remove the corrugating roller, insert the new roller, shut off the air supply, release the valve, reconnect the steam platformafter which F-flute production can commence immediately.The entire roller replacement requires no tools like wrenches and takes merely 2-3 minutes, drastically reducing downtime and ensuring peak efficiency.

 

By adopting specialized equipment to focus on differentiated products, Yuying has cultivated a stable high-quality clientele and secured expansive market opportunities. This case proves that in today’s cutthroat corrugated packaging industry, differentiation is not only a critical pathway for enterprises to rise above competition, but also represents the definitive direction for the entire corrugated packaging industry.
