In the workshop of a sea buckthorn planting base in the northwest, boxes of filled sea buckthorn puree are about to be shipped nationwide. Unlike traditional packaging, the surface of the special-shaped bags of these products is uneven, and the seal is printed with a striking brand totem. Consumers can lock it in from similar products on the shelf at a glance by touch. "This is thanks to the implementation of the special-shaped bag packaging solution." The person in charge of the base pointed to the bag-feeding packaging equipment on the production line and said.
Seabuckthorn puree has high viscosity and is easy to oxidize. It is easy to leave bubbles when filling in traditional bags, and loose sealing can also cause leakage. What is more difficult is that the stereotyped packaging makes the products drowned in homogeneous competition. In this regard, ply-pack's special-shaped bag packaging solution starts from customized design: users can work with suppliers to develop special-shaped bags in advance, confirm the bag curvature, capacity and material through 3D modeling, and then use the bag-feeding packaging machine to complete precise filling and sealing. This "design first, then produce" model allows the packaging form to be deeply bound to the product characteristics. For example, the curved bag bottom design for seabuckthorn puree can reduce liquid residue; the angular sealing enhances the sealing and extends the shelf life.
The core equipment of the solution, the bag-feeding special-shaped bag packaging machine, adopts a modular design. Its dual-channel filling system can automatically adjust the flow rate to ensure that the high-viscosity raw pulp evenly fills the complex structure of the special-shaped bag; the temperature control accuracy of the heat sealing module is ±0.5¡æ, and with the pressure adaptive technology, it can achieve zero leakage even in the face of the irregular sealing line of the customized special-shaped bag. More importantly, the equipment supports fast mold change, and the same production line can be compatible with more than 5 types of special-shaped bags, seamlessly switching production tasks. A cooperative enterprise reported: "In the past, it took 4 hours to stop the machine to change the bag type, but now it can be debugged in 20 minutes, which truly achieves flexible production."
The implementation of this solution not only optimizes the production process, but also reconstructs the supply chain collaboration logic. Ply-pack joins upstream and downstream suppliers to provide customers with one-stop services from special-shaped bag design, material procurement to equipment debugging. For example, in order to highlight the concept of "natural and additive-free", a brand customized a translucent frosted special-shaped bag, and the inner layer uses food-grade aluminum film light-blocking material. This deep collaboration allows packaging to be transformed from a cost item to a brand value-added point. Data shows that for enterprises adopting this solution, the premium space of terminal products has increased by an average of 15%-20%.
As the demand for healthy consumption upgrades, niche categories such as seabuckthorn puree are moving towards the mass market. The value of the special-shaped bag packaging solution lies in using technology to turn "differentiation" into a replicable standardized process. As a customer exclaimed during acceptance: "Now our packaging speaks for itself." As more and more brands tell stories through customized special-shaped bags, packaging is no longer just a container, but an emotional bond between products and consumers.
