The morning mist at the foot of the Helan Mountains has not yet dissipated, and the workshop of the Yongning Sea Buckthorn Processing Factory has been roaring. Factory Director Ma Bin grabbed a bag of sea buckthorn pulp that had just come off the line, and his fingertips stroked the undulating wave pattern on the bag body-this is their newly used customized special-shaped bag, inspired by the Helan Mountain rock painting totem. "Half a year ago, our products were still piled up in the warehouse and covered with dust. Now we have to send three trucks of goods every day." He stroked the angular sealing line of the packaging bag, and his tone was full of emotion.
As the earliest enterprise engaged in deep processing of sea buckthorn in Ningxia, Yongning Factory once suffered from outdated packaging. The raw juice packaged in traditional upright bags is always mistaken by consumers as "cheap juice" on e-commerce platforms. Even with excellent quality, the monthly sales volume always hovers around 2,000 boxes. What's worse, the highly viscous sea buckthorn raw juice has serious residues in ordinary bags, and the negative review rate is as high as 12%. "We tried to change the packaging design, but the bag shape remains unchanged. No matter how beautiful the label is, it's like changing the soup but not the medicine." Wang Xia, the purchasing director, shook her head as she flipped through last year's report.
The turning point came after the introduction of special-shaped bag packaging machine. With the support of ply-pack's technical team, Yongning Factory first jointly developed an exclusive special-shaped bag with upstream suppliers: the bottom adopts a 15° inclined arc design, which reduces the residual amount after filling by 60%; the bag mouth is embedded with anti-counterfeiting serrated edge sealing, which not only improves the sealing performance but also becomes a visual logo. The dual-channel filling system of the bag-type special-shaped bag packaging machine allows the viscous original pulp to evenly fill the complex structure of the special-shaped bag, and the sealing temperature is precisely controlled at 132±0.5¡æ, completely solving the leakage problem.
"The most surprising thing is the flexibility of production." Ma Bin pointed to the production line that was changing the mold and explained that the same equipment is now compatible with four types of special-shaped bags from 300ml to 500ml, and the changeover time is compressed from 4 hours to 35 minutes. This allows the factory to undertake small batch custom orders. The "mountain-shaped special-shaped bag" customized by a certain Internet celebrity brand took only 72 hours from design to mass production.
Three months after the new packaging was launched, the search volume of sea buckthorn original pulp of Yongning Factory on e-commerce platforms soared by 470%. In consumer evaluations, "the packaging has texture" and "recognize your home at a glance" have become high-frequency words. Even more unexpected is that a supermarket chain displayed the product in the imported food area, and the purchasing manager said bluntly: "The shelf impact of the special-shaped bags makes us willing to give a premium space."
Standing in the storage area, Ma Bin watched the workers load the last batch of "Rock Painting Series" to Shanghai. The special-shaped bag packaging machine was still roaring in the twilight, and the LED screen in the workshop was jumping with the daily output: 38,720 bags. This northwest factory, which once worried about unsalable products, is now using customized packaging technology to write a new chapter for the brand of Chinese agricultural products.
