Yili Da has overcome the challenge of mass-producing 6.2-meter ultra-long paper tubes

Recently, Qingdao Yili Da Packaging successfully delivered 6.2-meter ultra-long rectangular paper tubes. This achievement marks another significant breakthrough in technology and manufacturing. In recent years, few similar products in the industry have achieved mass production of the same ultra-long specifications. During the production of samples, many problems arose. Through continuous optimization and innovation by the technical team, the product successfully passed various performance tests, including process inspection, dimensional accuracy, and load protection. All indicators met industry standards and customer customization requirements, signifying a new breakthrough in the company's production process of ultra-long-sized packaging tubes.

As an enterprise with over 20 years of experience in producing paper packaging products, we deeply understand the load-bearing requirements of each product and the appropriate product specifications. We can precisely provide customers with the solutions they desire. When providing product information to customers, we immediately offer the optimal packaging solution. We adjust the tube gap to the minimum to maximize the utilization of the space for the packaged products.

During the production process, the company's technical team urgently adjusted the process formula and made precise micro-adjustments to the core molds of the production line. The production line employees also stayed up all night, monitoring the temperature and the speed of the rolling tube material. Finally, the product was successfully formed once. For the problem of the 6.2-meter ultra-long tube being difficult to pull out smoothly, wax was applied on the surface of the product, significantly reducing the friction coefficient and ensuring smooth pulling of the ultra-long tube.The successful delivery of this product not only serves as a powerful proof of the company's production process and R&D capabilities, but also fills the gap in the category of large-sized customized packaging products. It further improves the company's packaging product system, which covers both long and short specifications and is compatible with both high and low-end products.
