  • Open top provides ventilation and immediate product visibility

About this product

This heavy-duty, open-top corrugated tray holds bulk goods for stable pallet stacking and immediate retail display. Using corner tabs that lock into slots in the adjoining walls, it holds the tray square without tape, glue, or staples.

Because it relies on mechanical corner locks, packers erect it by hand at the bench. It fits supply chains moving goods on pallets or inside master cartons, though the open top means it requires an outer box for individual parcel shipping.

Common uses

  • Retail-ready display
  • Agricultural produce packing
  • Industrial parts staging
  • Beverage and heavy bottle distribution

Palletized Distribution and Retail Display

Retail-ready bulk goods

The unglued interior and open top frame products clearly for the shelf. Retail staff move loaded trays directly from the delivery pallet to the aisle without unpacking individual units.

Field-to-shelf produce

The open design allows field heat to escape and accommodates varying product heights. The reinforced end walls bear the weight of stacked pallets, protecting delicate fruits and vegetables.

Industrial parts staging

For manufacturing environments, the tray contains heavy components securely while allowing assembly workers to access parts quickly without opening flaps or cutting tape.

Beverage and heavy bottle distribution

The double-thick end walls handle the high base weight of glass or liquid containers, while the open top allows fast picking in warehouse environments.

Agriculture, Bulk Retail, and Industrial Parts

Agricultural packhouses

Farms and distributors rely on the ventilation and stacking strength to move fresh goods through cold chains and directly into grocery displays.

Commercial bakeries

Provides a rigid, breathable carrier for baked goods moving between commercial kitchens and retail locations, preventing lateral crushing.

Club stores and bulk retail

Fits the warehouse club model where unitized pallets move straight from the truck to the floor, requiring immediate product visibility.

When to consider glued or closed packaging

High-speed automated packing lines

If your facility uses automated tray erectors, the manual friction locks on this tray will slow down the line. A machine-erected glued tray is a better fit for high-volume, automated environments.

Single-item parcel shipping

Because the top is open and friction locks can disengage during drop impacts, this tray requires an outer master carton for mixed-carrier transit. If you ship directly to consumers, consider a closed mailer.

Close variants and lookalike dielines

The closest library neighbors include EVC30021_1, 0436.1a, 0436.1. 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, assembly, and route choices

Board thickness and lock binding

The 180-degree roll-over walls are highly sensitive to board thickness. While fine flutes fold crisply, heavy double-wall board can cause the hinges to crack and the locks to bind. If the package needs double-wall strength, the fold clearances require precise tuning.

Manual assembly labor

Packers erect this tray by hand. While it requires no tape or glue, rolling the double-thick end walls and forcing the friction tongues into the base slots requires repetitive thumb pressure. Consider your pack-bench volume before committing.

Board footprint and die-cutting

The extended roll-over flaps and specific lock holes require a larger corrugated footprint than a simple glued tray. The cross-shaped flat blank reduces nesting efficiency, making the board-to-volume ratio an important comparison point.

Master carton requirements

If the tray moves through individual courier networks rather than staying on a pallet, you must size it to fit inside a closed outer shipper to prevent the friction locks from opening during transit.

Adjusting locks, ears, and ventilation

Stacking ears and alignment tabs

The top edges of the walls can include upward-pointing tabs that interlock with the tray above, improving vertical stability for tall pallets.

Locking tongue friction

The size of the base holes and locking tongues can be adjusted to balance assembly speed against locking security. Tighter clearances hold better but require more effort to assemble.

Ventilation cutouts

You can add hand holes or cooling slots to the side walls for agricultural use, provided they do not compromise the double-thick end walls carrying the vertical load.

Board and packing details

Print surfaces and friction zones

The tray offers flat surfaces for branding. However, internal locking areas and base slots must remain clear of high-gloss varnishes, which reduce friction and cause the tray to spring open.

Additional notes

Board caliper and fold clearance

The mechanical locks depend entirely on precise fold allowances. Changing your board grade later requires adjusting the cutting die to ensure the tray still locks correctly.

FAQs

Shipping and Route

Can this tray ship through mixed-carrier networks?

Not as a standalone package. The open top exposes the product, and drop impacts can disengage the friction locks. It requires an outer master carton for individual shipping.

Assembly and Packing

Does this tray require glue or tape to stay together?

No. It uses mechanical friction locks. The end walls roll over 180 degrees and insert locking tongues into holes in the base, holding the tray rigid without adhesives.

Production and Routing

Why does this tray require die-cutting?

The specific shapes of the locking tongues, the base holes, and the double-creased roll-over hinges cannot be cut on standard straight-line equipment. A flatbed or rotary die-cutter creates the interlocking mechanism.

Materials and Board

Can this be made from heavy double-wall corrugated board?

It is possible, but it introduces risk. The 180-degree roll-over walls must wrap around the corner flaps. If the board is too thick, the hinges can crack and the locking tongues may fail to reach the base slots. The fold clearances must be carefully adjusted for heavy board.

Assembly and Packing

Is this suitable for automated packing lines?

Generally, no. The 3D roll-over locking sequence is designed for manual assembly at a pack bench. High-speed automated lines typically use glued trays instead.

Print and Finish

Can I apply a glossy finish to the inside of the tray?

It is best to avoid slick finishes near the locking tabs. Because the tray relies on friction to stay assembled, high-gloss coatings can cause the tongues to slip out of the base slots.

Stacking and Storage

How does this tray handle top-heavy pallet loads?

The double-thick end walls carry the vertical weight. When combined with optional stacking ears, the trays align securely on the pallet, preventing lateral shifting under heavy loads.

Product Fit

Do the package needs a separate lid for this tray?

It depends on your distribution route. Pallets can be stretch-wrapped directly over the open trays, but if the trays are separated for individual transit, they must go inside a closed master carton.
