Who is the largest box maker?

I'm curious to know, who exactly holds the title of being the largest box Maker in the industry? Is there a particular company that dominates the market, or is it a more competitive landscape with several players vying for the top spot? I'm interested in understanding the scale of their operations, their global reach, and any notable achievements or milestones they may have accomplished in their pursuit of being the leading box maker. Additionally, I'm wondering if there are any factors that have contributed to their success, such as innovative technologies, strategic partnerships, or a strong focus on sustainability.
