Our Activities

2026 Japan
Packaging Contest

— Industrial Packaging Category Award

AWARDED IN SEPTEMBER 2026

Our 100% corrugated cardboard export packaging solution for industrial sewing machines replaces conventional EPS (expanded polystyrene) cushioning while improving logistics efficiency and environmental performance.

66% LESS STORAGE SPACE
1.5× CONTAINER LOADING CAPACITY
By rethinking conventional industrial packaging, we developed a high-performance, 100% cardboard solution that provides cushioning protection equivalent to EPS. Because the components are stored as flat sheets, it achieves a 66% reduction in storage space. Its compact, precisely engineered layout also increases container loading capacity by 50%, allowing 480 units per container instead of the conventional 320. Together, these improvements deliver significant economic and environmental benefits across global supply chains.
