Heavy-duty packaging materials (for export), recognized worldwide Tri-Wall Pak®

Tri-Wall Pack is synonymous with triple-wall reinforced corrugated cardboard, serving as a heavy-duty packaging material that replaces wood, steel, and plastic.

It meets global standards, including the U.S. federal specification PPP-B-640d, one of the world’s strictest and its superior quality is highly trusted across the logistics industry worldwide.

The double-wall “Bi-Wall Pack” is also widely used around the world as a heavy-duty packaging material.

Benefits of switching from wooden boxes to Tri-Wall Pack

In international transportation
Reduction of total logistics costs　Reduction of CO₂ emissions　
Performance capable of withstanding harsh transportation conditions
Achieving these goals, we provide solutions to our customers’ logistics challenges.

Lightweight	Compared to wooden boxes, the weight is only 1/3 to 1/4. In air transport, where freight charges are often based on weight, this provides a significant advantage, achieving substantial cost reduction.
Space-saving	Compared to wooden boxes, the external volume is greatly reduced. This improves truck and container loading efficiency, significantly contributing to lower transportation costs.
Reduction of packaging material costs	Compared to wooden boxes, we offer an average of over 15% reduction in material costs. Additionally, waterproof paper or film is not required.
High strength	Tri-Wall Pack has higher compressive strength than wooden boxes and can withstand stacking with approximately 10 times the compressive strength of standard cardboard.
Outstanding weather resistance	It uses a water-resistant long-fiber liner. Additionally, its moisture content is low at 8–9% (compared to over 20% for wooden boxes), and the pH is nearly neutral, providing excellent rust prevention.
CO₂ reduction	Reduced external volume and lighter weight help lower CO₂ emissions during transportation. Recycling also reduces CO₂ from disposal and incineration.
Environmentally friendly	Compared to wooden boxes, it reduces wood resource usage by 60%. It contains no hazardous substances such as lead or mercury, supporting companies green procurement initiatives.
