About this product

The EVF31023 is a folding carton tray designed for premium presentation, fast manual assembly, and leak resistance. It features two pre-glued walls and continuous webbed corners (gussets) that fold inward, creating a clean, double-thick perimeter without exposed raw edges.

Delivered flat, the tray erects quickly at the packing station. Pulling the pre-glued walls upright automatically folds the gussets, allowing the remaining two walls to roll over and lock securely into the base. This tray is a strong choice for bakery, food service, and retail applications where containing crumbs or minor spills is a priority.

Bakery, Food Service, and Premium Kitting

Bakery and food service containment

The continuous webbed corners eliminate cut gaps at the bottom of the tray, making it very effective at containing crumbs, powders, or minor liquid spills. When paired with an appropriate food-safe coating, it provides a clean, secure presentation for baked goods or prepared foods.

Premium retail presentation

Because all four walls fold over to create a double-thick perimeter, raw board edges are hidden. This creates a polished, high-end look suitable for cosmetics, apparel, or gift kitting.

Component kitting and gift sets

The double-wall rigidity and clean edges make this tray a strong base for holding custom inserts, bottles, or multi-item gift sets. The sturdy perimeter helps protect heavier items during retail handling.

Medical or cosmetic trays

The lack of exposed raw edges and the clean interior presentation suit high-end personal care or clinical products where dust or raw fibers are undesirable.

Manual Packing Stations and Storage Efficiency

Manual packing stations

This tray is built for hand assembly. The pre-glued walls mean the operator simply pulls the sides up, folds the locking panels over the gussets, and presses the tabs into place. It sets up without tape, glue, or specialized equipment at the fulfillment stage.

Single-sided print programs

The roll-over wall construction means the inside of the tray walls is formed by the same side of the board as the outside. This allows brands to achieve full interior and exterior graphics while only paying for single-sided printing.

High-volume flat storage

Even though two walls are pre-glued during manufacturing, the tray ships knocked down (KD). This maximizes pallet density for facilities with limited storage space while still offering fast assembly on the floor.

Automated Loading and Parcel Shipping

Automated robotic loading

The manual roll-over locking walls make this tray difficult to erect on conventional automated packaging lines. If your facility uses high-speed robotic loading, a conventional 4-corner glued tray or a machine-erected top-load carton is usually a better fit.

Heavy parcel shipping

As an open-top tray, this package is not meant to be shipped through parcel networks on its own. It should be placed inside a secure outer shipping box or fitted with a locking sleeve to protect the contents during transit.

Cost-sensitive single-use applications

If the double-wall presentation and leak resistance are not needed, a conventional unglued roll-end tray uses less board and avoids the pre-gluing step, making it a simpler choice for basic containment.

Board Caliper, Coatings, and Locking Friction

Board caliper and fold clearance

The thickness of your chosen paperboard directly affects how the locking walls roll over the folded gussets. Thicker boards or micro-flutes may need specific adjustments to the crease offsets to prevent the board from cracking or binding during assembly.

Locking tab friction

The bottom and side locking tabs rely on friction to hold the tray together. The height and angle of these tabs can be tuned during prototyping to ensure they lock securely without demanding excessive force from the packing operator.

Coating for moisture resistance

While the webbed corners contain dry crumbs, packing wet or greasy foods means the board itself needs an appropriate barrier coating to prevent moisture from weakening the tray.

Insert compatibility

If using a custom insert, the internal dimensions should account for the slight inward draft or bulk of the rolled-over locking walls to ensure a proper fit.

Crease Tuning and Tab Adjustments

Layer step crease tuning

The template includes a specific adjustment for the layer step crease, which ensures the inner panels have enough clearance to fold cleanly over the bulk of the hidden gussets. This is matched to your exact material thickness.

Locking tab height and bevel

The tongue height and bevel angle of the locking tabs can be adjusted to balance secure retention against the force needed by the packing operator.

Webbed flap offset

The geometry of the hidden corner gussets can be modified to ensure they fold flat without binding, especially when using thicker paperboard.

Packing details

Folder-gluer manufacturing route

This tray is typically processed through a straight-line folder-gluer during manufacturing to secure the two pre-glued walls. While this adds a production step compared to unglued trays, it reduces labor time at the final packing station.

Additional notes

Manual packing speed

Because pulling the pre-glued walls upright automatically positions the gussets, operators only need to execute two roll-over folds to complete the tray, making it efficient for hand-packing lines.

FAQs

Does this tray need glue or tape during packing?

No. The manufacturer pre-glues two of the walls. At the packing station, the operator simply folds the remaining walls over the gussets to lock the tray into its final shape.

Is the tray waterproof?

The webbed corners prevent minor leaks and contain powders or crumbs because there are no cut gaps at the bottom. However, true waterproof performance depends entirely on selecting a board with an appropriate barrier coating.

Can I print graphics on the inside of the tray?

Yes. Because the inner walls are formed by folding the board over, you can place interior graphics on the same side of the flat sheet as the exterior graphics, simplifying the print process.

Can this be made from corrugated board?

It is primarily designed for folding carton board. While thin micro-flutes might work, the bulk of the folded gussets can cause the locking walls to bind, meaning careful structural adjustments and physical testing are necessary.

Can I ship this tray directly in the mail?

No, this is an open-top presentation or containment tray. For parcel shipping, it should be placed inside a secure outer shipping box or fitted with a locking sleeve.

Why are two walls pre-glued?

Pre-gluing two walls at the factory allows the tray to ship flat while enabling the webbed corners to fold automatically when the tray is opened. This speeds up manual assembly compared to completely unglued trays.

How does the double-wall structure affect internal dimensions?

The rolled-over walls add thickness to the perimeter. The internal usable space will be slightly smaller than the outer footprint, which should be checked if fitting precise inserts.

Do the webbed corners add bulk to the tray?

Yes, the folded gussets sit inside the left and right walls. The layer step crease is adjusted so the inner wall panels can roll over this bulk smoothly without tearing the board.
