How is corrugated board constructed?
Corrugated board combines flat liners with fluted paper forming a cushioning layer between them. Three-ply board has one flute layer between two liners; five- and seven-ply board add alternating flute and liner layers for greater thickness and strength. This is a general description of corrugated board, not a specification exclusive to FUCACO products.
Ply count is not the only factor in strength
Paper grade, flute type (B, C, E and others), box dimensions, load, handling and transport conditions all affect carton strength and protection. Ply count is one factor, not the sole measure of packaging durability.
Choosing a suitable carton structure
FUCACO's 2023 Company Profile lists 3-, 5- and 7-ply corrugated board and custom die-cut boxes for different packaging needs and loads.
