About this product

This heavy-duty, unglued corrugated tray is used for agricultural produce and baked goods. It uses reinforced fold-over end walls and an open top for loading and display.

The standard dieline has no native side ventilation cutouts. It ships flat and assembles manually at the packing station.

Common uses

  • Farm-level produce packing
  • Bakery and confectionery distribution
  • Cold chain logistics requiring airflow
  • Field-to-shelf display packing

Agricultural Transport and Retail Display

Fresh produce and agricultural transport

The side cutouts allow field heat to escape and prevent moisture buildup. The reinforced ends bear the weight of stacked pallets, keeping delicate fruits and vegetables protected during transit.

Retail-ready confectionery and baked goods

The open top frames the product for immediate shelf display. The rigid walls protect delicate items from lateral crushing before the final shrink wrap or master carton is applied.

Cold chain and refrigerated storage

When manufactured with moisture-resistant Kraft liners, the tray maintains its shape in refrigerated environments while the vents ensure consistent cooling across the pallet.

Field-to-shelf display packing

Because the tray requires no glue, workers can erect it directly in the field or at the sorting bench, pack the produce, and send it straight to the grocery floor without repacking.

Farms, Bakeries, and Grocery Retailers

Farm-level packing stations

The unglued, flat-delivered format saves storage space. Workers can manually erect the trays directly in the field or at the sorting bench without specialized folder-gluer equipment.

Bakery and confectionery distribution

Distributors rely on the rigid roll-over walls to prevent delicate pastries from crushing, while the open top allows for quick visual inspection and immediate retail presentation.

Grocery and supermarket retail

Store employees can move these trays directly from the delivery pallet to the produce aisle. The built-in ventilation keeps goods fresh, and the clean lines present well to shoppers.

When to Compare Solid Trays or Flanged Shippers

Need to ship individual units via parcel

The open top offers no protection against drops or sorting machines. Review a fully enclosed mailer or use this tray strictly as an inner component within a master shipper.

Heavy interlocking pallet loads

If the trays need to lock into each other vertically for extreme stability, look at the 0432. It adds top flanges and stacking ears to prevent shifting.

Close variants and lookalike dielines

The closest library neighbors include 0431, 0432, 0482. Use this as a variant check if a buyer brings an old code, sample, or dieline that looks close. The deciding details are usually the lock, slot, closure, wall build, part count, or fold sequence.

Board Thickness, Moisture Resistance, and Assembly

Board thickness and fold clearance

The 180-degree roll-over walls must wrap around the inner corner flaps. Specifying a thick double-wall board requires precise crease adjustments, otherwise the hinges will crack and the locking tabs will pop out.

Die-cutting and stripping waste

The ventilation holes generate internal cardboard scrap. Large production orders require a converter with reliable stripping equipment to prevent machine jams and ensure no scrap ends up in food areas.

Moisture resistance needs

Agricultural and cold-chain routes often require specific Kraft liners or moisture-resistant coatings to prevent the corrugated fluting from absorbing water and collapsing under pallet weight.

Manual assembly speed

Operators must fold the side flaps inward and roll the end walls over them, applying firm thumb pressure to seat the tabs. This repetitive motion should be factored into packing line speed.

Ventilation Cutouts, Crease Tuning, and Slot Styles

Ventilation hole sizing

The side cutouts can be enlarged for better airflow or shaped to serve as carrying handles. Removing too much material will reduce the tray's overall vertical crush resistance.

Locking tab and slot styles

The base slots can be cut straight or tapered. Tapered slots often strip cleaner on the die-cutter, reducing the risk of loose cardboard scrap.

Double crease (DC) tuning

For heavy agricultural boards, the template's double creases must be widened. This ensures the 180-degree roll-over hinge folds cleanly without tearing the outer liner.

Board and packing details

Blank sprawl and material yield

The extended roll-over panels create a large, cross-shaped flat blank. This limits how many trays can be nested on a single sheet of corrugated board, which affects material efficiency compared to simpler slotted trays.

Additional notes

Internal stripping waste and food safety

The cutouts for the side vents generate small pieces of scrap board. When packing exposed produce or baked goods, ensure your converter uses reliable stripping equipment so loose cardboard does not end up in the delivered trays.

FAQs

Route and Shipping

Can this tray be shipped through standard parcel networks?

Not on its own. The open top leaves products exposed, and the friction locks release under drop shock. It must be shrink-wrapped or placed inside a sealed master carton for courier transit.

Production and Board Choice

Can we use heavy double-wall corrugated for extra stacking strength?

Yes, but the template must be carefully adjusted. The end walls roll 180 degrees to lock the tray. If the board is too thick and the creases are not widened, the hinges will bind and the tray will spring open.

Packing Labor

Does this tray require a gluing machine to assemble?

No. It is entirely unglued and relies on mechanical friction tabs. It is typically erected by hand at the packing bench, though specialized agricultural die-box plungers can automate the process.

Product Fit

Will the ventilation holes weaken the tray?

They do reduce the vertical compression strength of the side walls compared to a solid tray. The primary stacking weight is carried by the double-thick roll-over end walls, but heavy pallet loads should be physically tested.

Print and Finish

Where can graphics be printed on this tray?

The outer side and end walls offer clean print surfaces. Because the end walls roll over to the inside, the interior ends will show the unprinted side of the board unless you specify two-sided printing.

Production Route

Why does this tray require die-cutting instead of standard slotting?

The ventilation holes, locking tabs, and base slots cannot be cut by standard rotary slotter knives. It requires a dedicated cutting die to punch out the specific shapes and internal vents.

Assembly Mechanics

How does the tray stay locked without tape or glue?

The extended end walls roll over the inner corner flaps and feature small tabs at the bottom. These tabs insert firmly into receiving slots cut into the base panel, creating a secure friction lock.

Product Fit

Is this tray suitable for refrigerated storage?

Yes, provided the correct board grade is selected. For cold chain logistics, the tray should be manufactured with moisture-resistant Kraft liners so the corrugated fluting does not absorb condensation and collapse.
