Industrial & Export Packaging
Heavy-duty corrugator lines producing double-wall and triple-wall board for industrial export packaging — BC-flute for heavy machinery parts, appliances, and long-distance freight that must survive rough handling and long transit.
Industrial and export packaging requires the strongest corrugated board structures — double-wall and triple-wall that replace wood crating at a fraction of the weight. A BOSON 5-ply or 7-ply corrugator line, with multiple single facers and a heavy-duty double backer, produces the rigid, high-strength board that industrial and export applications demand.
Challenges We Solve in This Market
Board too weak for heavy loads
Single-wall board fails under heavy industrial products and long-distance stacking. Double-wall and triple-wall structures, produced with multiple single facers, deliver the edge crush strength export freight requires.
Wood crate weight and cost
Wood crating is heavy, expensive, slow to fabricate, and hard to recycle. Triple-wall corrugated board produced on a 7-ply corrugator matches wood's rigidity at a fraction of the weight — reducing freight cost and enabling on-demand fabrication.
Delamination under vibration
Long-distance trucking and shipping vibrate board apart if the bond is weak. A heavy-duty double facer with S-shaped airflow and multiple reinforcing ribs cures the adhesive uniformly for bond strength that survives rough transit.
The Dedicated Machine Combination
A BOSON 5-ply or 7-ply corrugator line uses multiple single facers and a heavy-duty double backer to bond three or four liners with two or three flute layers — producing the rigid double-wall and triple-wall board industrial export packaging demands.
Hydraulic Mill Roll Stands HS-B (×5–7)
Five to seven mill roll stands feed the multiple liners and fluting mediums a 5-ply or 7-ply line requires.
View DetailsPreheaters PH (×4–6)
Multiple preheaters condition each liner and fluting medium before bonding for consistent heavy-duty board.
View DetailsCassette Single Facers BS-MW25 (×2–3)
Two or three single facers create the multiple flute layers — each additional single facer adds one corrugated medium to the board structure.

Maintains adhesive viscosity for uniform bonding across all flute layers in thick board.
View DetailsThe Right Cardboard for This Market
Industrial and export packaging requires double-wall (5-ply) and triple-wall (7-ply) board for maximum strength and stacking. These structures use multiple single facers and a heavy-duty double backer to bond extra flute layers and liners.
Material Specifications
- Double-wall (5-ply): 3 liners + 2 flutes — heavy products and long-distance shipping
- Triple-wall (7-ply): 4 liners + 3 flutes — industrial freight, machinery, wood-crate replacement
- BC-flute double-wall: combined cushioning and stacking for appliance export cartons

Frequently Asked Questions
Can a corrugator line produce triple-wall board to replace wood crates?
Yes. A 7-ply corrugator line uses three single facers and a heavy-duty double backer to bond four liners with three flute layers, producing rigid triple-wall board that matches wood crating's strength at a fraction of the weight and cost.
What is the difference between a 5-ply and 7-ply corrugator line?
A 5-ply line uses two single facers to produce double-wall board (2 flutes + 3 liners), while a 7-ply line uses three single facers to produce triple-wall board (3 flutes + 4 liners) — adding one more flute layer and liner for maximum strength and rigidity.
