About this product

This single-piece corrugated tray ships flat but pops open instantly. Because the four corner webs are permanently glued during production, a packer simply pulls the side walls upward, and the entire tray squares itself into a rigid, open-top container.

It trades higher production preparation for massive labor savings on the pack bench. This makes it a strong choice for high-volume fulfillment, retail display, and produce packing, but a poor fit for short runs where the multi-point gluing preparation outweighs the time saved.

High-volume packing and distribution

Retail shelf-ready packaging (SRP)

The open top allows immediate product visibility and easy shelf placement. The reinforced, double-layered corners keep the tray square and presentable even after transit.

Chilled dairy and produce distribution

Often specified with wet-strength liners and ventilation holes, this tray allows airflow for cooling while maintaining enough vertical strength to stack loaded units on a pallet.

High-volume manual kitting lines

For operations assembling multi-part kits, the instant pop-up action keeps the line moving without dedicating a worker solely to folding trays.

Bakery and fresh food transport

The shallow depth and rigid corners make it suitable for transporting delicate baked goods or fresh foods that cannot bear top weight, provided the board is treated for moisture resistance.

Environments that benefit from instant setup

High-volume manual pack benches

When packing speed is the primary bottleneck, removing the step of manually folding and locking tray walls saves hours of labor across thousands of units. The operator uses two hands to pull the sides up, drops the product in, and moves to the next.

Automated or semi-automated fulfillment centers

While optimized for manual pop-up, the consistent flat delivery and predictable erection motion make this tray suitable for specific automated tray-forming equipment, provided the machinery is calibrated for 4-point glued blanks.

Cold chain logistics

Operations moving goods through refrigerated environments rely on this tray's ability to incorporate ventilation holes without losing the structural integrity provided by the glued, double-thickness corners.

When to look at a different tray or box

Short runs and low-volume orders

Setting up a multi-point folder-gluer takes time. For runs of a few hundred units, the preparation outweighs the benefits. Look at a manual fold-over tray (FEFCO 0422) instead, which requires zero gluing.

Parcel and courier transit

This is an open tray. It provides no top containment for individual parcels. If the package ships through a courier network without an outer master carton, look at an auto-erecting tray with an integrated lid (FEFCO 0748).

Close variants and lookalike dielines

The closest library neighbors include 0770, 0451_2, EVC41041. 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, volume, and structural choices

Board thickness and corner binding

This structure relies on diagonal creases acting as hinges. Fine to medium flutes (E or B) fold cleanly. Heavy single-wall or double-wall boards drastically increase pop-open resistance, risking corner binding or liner fracture during erection.

Production volume and order maturity

This tray requires a flatbed die-cutter and a multi-point folder-gluer. The preparation time is considerable. Ensure your order volume is high enough that the pack-bench labor savings justify the manufacturing path.

Wet-strength liner requirements

If the tray will hold chilled goods or move through damp environments, standard corrugated board will absorb moisture and weaken. Specifying a wet-strength kraft liner prevents condensation from degrading the walls.

Ventilation hole placement

Airflow cutouts must be positioned carefully to avoid intersecting the diagonal corner creases. Any material removed from the vertical walls will also reduce the tray's ability to bear top weight during palletization.

Practical template modifications

Ventilation and hand hole arrays

Circular cutouts can be added to the side or end walls for airflow or carrying. These must be placed carefully to avoid intersecting the diagonal corner creases, and they will reduce the overall vertical stacking strength of the tray.

Corner slot profiles

The top edges of the tray can be cut with straight or radiused slots to change the visual profile or accommodate specific stacking tabs, depending on the converter's stripping capabilities.

Dust flap score offsets

The exact position of the score lines on the inner flaps can be adjusted to ensure the walls fold perfectly flat against each other, accommodating different board thicknesses without binding.

Board and packing details

Pallet compression with vented walls

Load transfers down the four vertical walls and the double-thickness glued corners. If ventilation holes are added, the tray's ability to support heavy pallet weight decreases. Physical compression testing is recommended before a full rollout.

Tray variants and options

Straight or radiused slots

The top edges of the walls can feature straight cuts or rounded radius cuts, which may affect how easily the waste board is stripped during die-cutting.

Additional notes

Flat delivery and storage footprint

Despite having four glued corners, the tray collapses completely flat. It takes up minimal warehouse space before use, similar to an unglued blank.

FAQs

Production and volume

Why choose a pre-glued tray over a manual folding tray?

It comes down to volume and labor. A manual tray is simpler to produce but slower to pack. A 4-point glued tray requires more production preparation but erects instantly. At high volumes, the labor saved on the pack bench easily justifies the gluing process.

Board and fit

Can we use heavy double-wall board for extra strength?

It is highly discouraged without physical testing. The tray relies on the corner webs folding inward. Thick boards create too much resistance, causing the corners to bind or the liner to tear when a packer tries to pop the tray open.

Shipping and route

Can this tray ship through parcel networks?

Not on its own. Because it has an open top, it requires a separate lid, shrink wrap, or insertion into an outer master carton to ship safely through a courier network.

Handling

Can workers carry heavy payloads by the side walls?

The base panel distributes weight to the edges, but relying entirely on the side walls to lift a dense, heavy payload can put excessive stress on the glued corners. Heavy items should be supported from the bottom.

Modifications

How do ventilation holes affect stacking strength?

Any material removed from the vertical walls reduces the tray's ability to bear top weight. If you add airflow or hand holes, you should run a physical pallet crush test to ensure the remaining board can support your stacked product.

Route and shipping

Does this tray work in chilled or damp environments?

Yes, it is frequently used as a dairy or produce tray. However, standard corrugated board absorbs moisture. For chilled logistics, the tray should be specified with a wet-strength kraft liner to prevent condensation from degrading the walls.

Assembly

Does this tray require tape or staples to stay open?

No. The four corner webs are permanently glued during production. When a packer pulls the side walls up, the tension of the folded webs holds the tray square and open without additional fasteners.

Storage

How is this tray delivered to the packing facility?

It arrives knocked-down flat (KDF). Despite the glued corners, the tray collapses completely, taking up minimal warehouse space before use.
