What it is
Medium (Fluting Paper) is a specially engineered paper used to form the corrugated (wave-like) layer between liner boards in corrugated packaging. It is designed to provide cushioning, structural support, and compression strength, making it a critical component in the overall performance of corrugated boxes. Produced using recycled fibers, it offers the flexibility required to create consistent flute formation without cracking or breaking.
The performance of fluting paper directly impacts the durability and load-bearing capacity of corrugated boards. A well-engineered medium ensures uniform flute structure, better bonding with liners, and improved resistance to crushing under pressure. Medium paper plays a silent yet vital role in protecting goods during storage and transportation, especially in demanding logistics and export environments.
