  • Unglued mechanical locks resist moisture failure in cold-chain and agricultural routes
  • Inner walls hide raw corrugated edges for a clean retail presentation

About this product

This single-piece corrugated tray uses 180-degree fold-over walls to create a highly rigid, double-thick perimeter without adhesive. The inner walls roll completely over the outer walls, trapping the corner flaps to form four-layer corners that provide exceptional stacking strength.

Because it ships completely flat and relies on mechanical friction locks, it is a frequent choice for heavy agricultural goods, cold-chain transport, and retail displays where clean edges and moisture resistance matter more than instant assembly speed.

Common uses

  • Agricultural and meat packing
  • Heavy retail displays
  • Industrial parts kitting
  • Dense beverage and jar packaging

Heavy payloads and retail presentation

Agricultural and cold-chain transport

Standard adhesives can weaken in high-humidity environments like produce coolers or meat packing facilities. This tray relies entirely on mechanical friction locks, maintaining its shape even when exposed to condensation.

Heavy retail displays

The 180-degree fold-over walls hide the raw, fluted edge of the corrugated board. This creates a clean, smooth top edge that looks professional on a retail shelf, while the double-thick walls prevent the tray from bowing under the weight of dense products like jars or canned goods.

Industrial parts kitting

For heavy metal components or dense hardware, the four-layer corners provide the vertical crush resistance needed to stack fully loaded trays on a pallet without the bottom layers collapsing.

Dense beverage and jar packaging

When packing glass jars or heavy beverage cans, the double-wall perimeter prevents the side panels from bulging outward during transit, keeping the payload tightly contained.

Supply chains relying on unglued strength

Grocery and food distributors

Often referred to in the industry as a meat tray, this package handles dense, wet, or chilled goods reliably because it does not depend on factory-glued seams.

Retail merchandising teams

The unglued construction means the tray can be printed on a single side of the flat board, yet display those printed graphics on both the exterior and interior walls once folded.

Agricultural packers and farms

Because the trays ship completely flat, farms and packing houses can store massive quantities in minimal warehouse space, assembling them in the field or packing shed as needed.

When to consider a different tray style

High-speed packing lines

If the packing team needs instant, one-motion assembly, compare this to a pre-glued crash-lock tray. The double-wall tray requires deliberate, two-handed manual folding to seat the locking tabs.

Lightweight or budget-sensitive goods

Because all four walls fold completely over, this tray uses significantly more corrugated board than a standard tray. If the product is light and does not require double-wall strength, a standard friction-locked tray will be more economical.

Close variants and lookalike dielines

The closest library neighbors include 0761, 0456, 0759. 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, labor, and print decisions

Board grade and foldability

The defining feature of this tray is the 180-degree fold. While it provides immense strength, specifying a board that is too thick or stiff can cause the inner liner to crack during assembly. Fine to medium flutes generally fold cleanly.

Pack-bench labor

This tray ships completely flat, which maximizes pallet density and saves warehouse space. However, it shifts the assembly burden to the packing team. Plan for a sequential folding process rather than an instant pop-up motion.

Print coverage and branding

Because the interior walls are formed by folding the exterior perimeter inward, a single-sided print run covers both the outside of the tray and the inside walls. This allows for full-color retail branding without the cost of two-sided printing.

Pallet stacking behavior

The load-bearing capacity of this tray is concentrated in the corners, where the folded flaps create four layers of corrugated board. When stacking on a pallet, aligning these corners precisely is critical to preventing the side walls from bowing.

Tray modifications and base options

Locking tab profiles

The shape of the base slots and locking tabs can be adjusted from squared to rounded or tapered. This ensures the tabs seat firmly without tearing the base panel during assembly.

Corner flap sizing

The internal corner flaps can be extended or shortened. Longer flaps provide more corner rigidity for heavy stacking, while shorter flaps reduce the overall flat board size and material footprint.

Double-crease width

The top fold relies on a double crease to accommodate the board thickness. This gap must be precisely tuned to the chosen flute profile so the inner walls roll over smoothly without fracturing the printed liner.

Board and packing details

Blank size and material usage

Because all four walls fold completely over, the flat, unfolded board is significantly larger than a standard tray. This increases the material footprint, which is offset by the lack of factory gluing costs and the extreme structural strength gained.

FAQs

Assembly and Labor

Does this tray require tape or glue to stay together?

No. The tray uses mechanical friction locks. The inner walls fold over the corner flaps and secure themselves by pushing tabs into pre-cut slots in the base.

Can this tray be erected automatically by machinery?

While specific plunge-forming tray erectors can handle this style, it is primarily designed for manual assembly. If the packing line relies on automated folder-gluers, a different tray style is usually required.

Material and Board

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

It requires careful testing. Because the walls must fold 180 degrees, board that is too thick can crack along the crease or cause the locking tabs to bind. Often, a strong single-wall board provides enough strength due to the tray's double-wall folded design.

Shipping and Route

Is this suitable for shipping individual orders through a courier network?

Not on its own. As an open-top tray, it provides no top containment. For parcel shipping, it must be combined with a lid, shrink wrap, or placed inside a master outer carton.

Print and Finish

Do the package needs to pay for two-sided printing to have graphics on the inside?

No. The inner walls are formed by folding the outer edges of the flat board inward. A standard one-sided print will cover the exterior walls and the interior side walls once the tray is assembled.

Performance

Why is this often used for cold-chain or agricultural products?

Standard glues can soften and fail in high-humidity environments like produce coolers. Because this tray relies entirely on mechanical folds and locks, it maintains its shape even when exposed to moisture, provided the board itself is treated for wet strength.

Shipping and Route

How does this tray arrive at the facility?

It arrives completely flat. Because there are no pre-glued seams, it packs extremely densely on a pallet, minimizing inbound freight costs and warehouse storage space.

Assembly and Labor

What happens if the locking tabs do not seat correctly?

This usually indicates the board is too thick for the crease allowance, or the slots are too narrow. The double creases must be precisely matched to the board caliper to ensure the tabs lock without excessive force.
