About this product

This one-piece corrugated tray is built for heavy pallet loads and closed-loop logistics. It features wide, double-wall "bench" columns on the short ends and integrated stacking tabs, providing high vertical crush resistance without requiring a separate lid or glued joints.

The glue-free, roll-over assembly creates a very rigid tray that aligns securely on a pallet. Because the reinforced columns require large internal flaps and 180-degree folds, this design uses more material and requires a larger flat footprint than a standard open tray.

Common uses

Agricultural produce transport requiring ventilation and crush resistance.
Industrial parts kitting for heavy metal components.
Closed-loop logistics where trays are reused and stacked repeatedly.
Warehouse club retail displays for heavy bulk goods.

Heavy-Duty Transport and Kitting

Agricultural produce transport

The thick bench columns prevent heavy, stacked trays from crushing the fruit or vegetables inside. The open top allows for necessary ventilation and field-packing access.

Industrial parts kitting

Useful for moving heavy metal components between assembly stations. The open access speeds up line work, while the rigid corners handle the weight of stacked metal parts.

Closed-loop logistics

A strong fit for internal supply chains where trays are palletized, transported, emptied, and reused. The mechanical locks hold up well to repeated handling.

Warehouse club retail displays

Because these trays stack securely on pallets without crushing, they are often used to ship heavy bulk goods directly to warehouse club floors where the pallet becomes the display.

Agriculture and Industrial Logistics

Produce growers and distributors

Agricultural supply chains rely on these trays to move goods from field to grocer without bruising the product. The stacking tabs ensure tall pallets remain stable during transit.

Manufacturing and assembly lines

Facilities moving heavy sub-assemblies use columned trays to keep parts accessible while maximizing vertical storage space on the factory floor.

Warehouse club suppliers

Brands selling heavy bulk items to big-box retailers use these trays to meet strict pallet-stacking requirements while keeping the product visible and accessible to shoppers.

When to Consider Simpler Trays or Shippers

Direct parcel shipping

This tray has an open top and no native sealing mechanism. If the product will travel through a mixed-carrier courier network, it requires a separate outer shipping box.

Lightweight retail display

The thick bench columns consume internal volume. If the payload is light and shelf space is tight, a standard roll-end tray provides more internal room for the product.

Board Grade, Flute Direction, and Assembly Method

Flute profile and direction

To maximize the crush resistance of the benches, the corrugated flutes should run vertically through the short walls. B-flute or C-flute is often selected for heavy agricultural or industrial loads.

Assembly labor and automation

This tray requires a specific folding sequence to trap the side flaps inside the bench columns. While it requires no glue, manual assembly takes longer than a simple auto-bottom box. High-volume operations often use specialized plunge-forming mandrels.

Moisture and environment

For produce or cold-chain logistics, the board may need specific moisture-resistant coatings or liners to prevent the load-bearing columns from softening in humid environments.

Internal volume constraints

The thick, double-wall bench columns consume internal space. The exact product arrangement should be mapped against the internal dimensions, not just the outer footprint, to ensure a proper fit.

Adjusting Column Width and Tab Clearance

Stacking tab alignment

If these trays need to interlock with an existing pool of legacy trays, the width and placement of the stacking tabs and base slots can be adjusted to match the older footprint.

Ventilation and hand holes

Cutouts for airflow or lifting can be added to the long walls or the base. They should be kept away from the load-bearing side flaps and bench roll-overs to maintain stacking strength.

Double crease width for thicker boards

If the payload requires a heavier C-flute or double-wall board, the distance between the parallel score lines must be widened to prevent the board from cracking when the walls roll over 180 degrees.

Packing details

Blank sprawl and material efficiency

Because all four walls roll over 180 degrees and the short ends require large internal flaps, the flat, unfolded blank is quite large. This reduces the number of trays that can be nested on a single corrugated sheet during flatbed die-cutting.

Additional notes

Print visibility on rolled panels

The outer walls and the top surfaces of the benches provide the primary print areas. The interior base is also visible when empty. Because the short and long walls roll over 180 degrees, the inside faces of those roll-over panels will be hidden after assembly.

FAQs

Does this tray require glue or tape to stay together?

No. All four walls roll over and lock mechanically into slots in the base. The short-end benches trap the internal flaps, creating a secure hold without adhesives.

Can this tray be erected on automated packaging lines?

It is generally incompatible with standard linear folder-gluers because it relies entirely on complex mechanical folds. Automated assembly requires specialized plunge or mandrel tray-forming equipment.

How high can these trays be stacked on a pallet?

Stacking height depends entirely on the chosen board grade, flute direction, and the weight of the product. The bench columns are designed for high vertical loads, but physical Box Compression Testing (BCT) should be used to validate specific pallet configurations.

Can we change the size or position of the stacking tabs?

Yes, but the tabs are formed by the internal side flaps protruding through cutouts in the bench panels. Modifying the tabs requires precise adjustments to the flaps, the cutouts, and the receiving slots in the base to ensure they still lock together.

Is this tray suitable for courier or parcel shipping?

Not on its own. The open top and mechanical locks are designed for stable pallet transport. Parcel networks require a sealed outer shipping box.

What board thickness fits this design?

E-flute provides a clean fold for lighter kitting, while B-flute or C-flute is common for heavy agricultural loads. Thicker boards require wider double-crease scoring to prevent the 180-degree roll-over panels from cracking or binding.

How does the flute direction affect the tray's strength?

To maximize the crush resistance of the benches, the corrugated flutes should run vertically through the short walls. This orientation provides the highest vertical compression strength for pallet stacking.

Can we add a lid to this tray?

This specific design is an open-top tray intended for stacking, where the tray above acts as a cover. If a sealed closure is required, a different box style or a separate outer shipper is usually a better choice.
