Heavy stacking and bulk display jobs
Agricultural produce and cold chain
The open sides allow airflow for cooling, while the corner posts carry the weight of stacked pallets without crushing the fruit or vegetables inside.
Heavy industrial components
Metal parts or dense hardware that need to be stacked high in a warehouse but accessed easily without opening a sealed box.
Club store bulk displays
Pallets that move directly from the truck to the retail floor. The posts provide transit stability, and shoppers can reach the product immediately.
Heavy-duty liquid transport
Beverage bottles or cans that require high top-load protection during pallet transit without needing a fully enclosed box.
Operations equipped for complex trays
High-volume automated packing facilities
Operations equipped with plunger-style tray erectors can form these trays at high speeds, making the complex fold sequence a non-issue.
Cold storage and ventilated transit
Supply chains that require constant airflow to prevent spoilage but cannot sacrifice vertical pallet strength.
Retail-ready pallet programs
Pallets that move directly from the delivery truck to the warehouse club floor, requiring both transit durability and immediate consumer access.
When to consider a different tray style
Standard roll-over trays for lighter loads
If your product does not require massive top-load protection, a standard FEFCO 0422 tray uses far less corrugated board and is easier to fold by hand.
Glued corner trays for standard machinery
If your facility uses standard hot-melt tray erectors rather than specialized pepper box machines, a glued tray will run more reliably.
Clearances, machinery, and payload space
Board thickness and fold clearance
The corner posts must roll inward tightly. If you specify a thick double-wall board without adjusting the fold allowances, the corrugated material will bind and the locking tabs will fail to seat.
Post width versus internal volume
Widening the corner posts increases stacking strength but directly reduces the usable space inside the tray.
Erecting machinery compatibility
You must match the die profile to the specific mandrel and plow clearances of your automated erector to prevent machine jams.
Base slot stripping and waste management
The lock slots in the base generate small cardboard cutouts. These must be cleanly removed during die-cutting so they do not jam automated packing lines later.
Modifying the corner posts and walls
Corner post footprint
The width and angle of the structural struts can be modified to balance payload space against required compression strength.
Base slot shape
The receiving slots in the floor can be cut square or rounded to improve how cleanly the waste cardboard strips out during die-cutting.
Wall height adjustments
Side and end panels can be raised for better product retention or lowered to increase retail visibility, provided the corner posts remain tall enough to carry the pallet weight.
Board and packing details
Blank sprawl and material yield
The extended flaps required to form the four columns create a massive flat footprint. This reduces how many trays fit on a single sheet of corrugated board, affecting overall material efficiency.
