Agricultural & Fresh Produce
Corrugated board production lines supplying ventilated produce trays and heavy-duty agricultural bins — A-flute for cushioning and C-flute for stacking, with controlled moisture management through precise starch application.
Agricultural and fresh produce packaging demands board that resists moisture from cold-chain condensation while providing ventilation and cushioning. A BOSON corrugator line produces A-flute and C-flute board with controlled starch application, giving produce-packaging converters a reliable supply of board engineered for the cold chain.
Challenges We Solve in This Market
Cold-chain moisture damage
Condensation in refrigerated transport saturates board, weakening flute structure and causing collapse. Controlled starch application and proper preheating produce moisture-resistant board that holds up through the cold chain.
Insufficient cushioning for fragile produce
Soft fruit and vegetables bruise without proper cushioning. A-flute's larger arch height provides the shock absorption produce trays need, produced to spec on a configurable corrugator.
Stacking failure under pallet weight
Produce bins must hold stacked pallet weight without crushing. Precise double-facer bonding produces rigid board with high edge crush strength for reliable stacking in distribution.
The Dedicated Machine Combination
A BOSON corrugator line configured for produce-packaging board produces A-flute and C-flute with controlled moisture and starch application — board that resists cold-chain condensation and stacks reliably.

View DetailsThe Right Cardboard for This Market
Produce packaging uses A-flute for cushioning and C-flute for stacking strength, with moisture-resistant starch bonding for cold-chain durability. An in-house corrugator lets you tune flute and moisture to each produce type.
Material Specifications
- A-flute: ~4.7 mm, largest arch height for maximum cushioning and stacking
- C-flute: ~4 mm, balanced stacking strength for produce bins and cases
- Moisture-controlled starch bonding for cold-chain condensation resistance

Frequently Asked Questions
Which flute type is best for fresh produce packaging?
A-flute (~4.7 mm) provides maximum cushioning for fragile produce like soft fruit, while C-flute (~4 mm) offers balanced stacking strength for produce bins and distribution cases. A configurable corrugator switches between them in 10 minutes.
How does the corrugator handle cold-chain moisture requirements?
The NC glue machine and full-auto glue-making station control starch adhesive viscosity and moisture, producing board with consistent, moisture-resistant bonding that withstands cold-chain condensation without delaminating.
