PACCO recently completed a rigorous three-month transportation and storage simulation test for its custom-designed kraft paper flange tubes, successfully meeting the approval of an overseas high-end textile client.

The client's textile fabric is characterized by its extremely soft texture and substantial weight per roll, requiring 2 to 3 months of sea freight and storage cycles. This placed exceptionally high demands on the tube’s long-term load-bearing stability and flange smoothness—any deformation of the tube or wrinkling of the flange could cause irreversible creases or damage to the fabric.

To meet these stringent requirements, PACCO’s R&D team began at the material level, carefully selecting specialty kraft paper and low-migration food-grade adhesive to ensure the tube body maintained high rigidity and environmental safety under prolonged load. In terms of production technology, an additional manual flange application process was incorporated after the standard industrial tube forming, achieving seamless adhesion between the flange and the tube body and avoiding stress-induced wrinkles that can occur with mechanical application.

After three months of testing simulating real-world logistics and storage conditions, the client confirmed that upon unrolling, the fabric remained intact, the tube stayed straight without deformation, and the flange remained completely smooth and wrinkle-free. This outcome successfully minimized the impact on the high-value fabric, achieving what can be described as “invisible protection.”

This collaboration fully demonstrates PACCO’s integrated capabilities in non-standard customization, material science, and process innovation, while also providing a reliable packaging solution for the long-term storage and long-distance transportation of high-value textiles.
