Most people are aware that conventional corrugated fiberboard is a paper-based construction consisting of corrugated "medium", sandwiched between layers of flat linerboard. The most commonly used corrugated board configurations are: single-wall, double-wall, and triple-wall.



Tri-Wall and Bi-Wall board differ from conventional corrugated board in several key aspects:

• Thickness: Bi-Wall 10mm, Tri-Wall 15mm.
• Use of virgin pulp paper.
  
• Weather resistant
  
• Key physical indicators such as strength, edge crush, puncture, etc., must conform to various military and civilian regulatory agency standards. Examples: IATA, UFC, Rule41, Item 222.
  

Tri-Wall, Bi-Wall have been used in a broad range of industries for their strength, flexibility and environmental friendliness.



Over the past several decades, packaging rationalization and reformation have elevated paper based products to an unprecedented position of importance. The clear trend, worldwide, is the demand for lighter, easier to handle, environmentally friendly packaging solutions.
