About this product

Self-locking trays with double side walls assemble entirely without glue or tape. By rolling the long side walls 180 degrees inward, this design traps the corner flaps and locks securely into the base, creating a clean interior and double-thick lateral protection.

Because the structural reinforcement is focused on the long edges, this tray frequently serves as the base for heavy-duty telescopic boxes, premium retail displays, and protective inner packaging for flat goods.

Common uses

  • Base component for a heavy-duty telescopic box.
  • Retail shelf-ready packaging.
  • Protective inner tray for flat media or electronics.

Telescopic Bases, Retail Displays, and Inner Trays

Telescopic box bases

Pairs with a separate lid to create a rigid, two-piece box for heavy or premium items. The double-thick side walls support the lid and resist crushing when stacked.

Retail and presentation trays

The rolled side walls hide raw corrugated fluting, providing a clean frame for products on a shelf. The glueless interior ensures a pristine presentation.

Protective inner trays

Fits inside a larger master shipper to organize flat goods, media, or components while absorbing side impacts during transit.

Component sorting and kitting

The rigid double walls keep heavy parts from bowing the tray outward, making it useful for organizing hardware or kits on an assembly line.

Retail Kitting, Flat Goods, and Component Sorting

Retail kitting and gift sets

The unglued interior ensures no adhesive residue touches the product, while the rigid sides keep inserts from bowing outward when multiple items are packed tightly.

Flat media and electronics

The reinforced long walls absorb lateral impacts during handling, protecting wide, shallow items that might otherwise punch through standard single-layer carton sides.

Agricultural and produce displays

When side ventilation or lateral strength is needed without relying on glue, the mechanical locks hold the tray square even in humid environments.

When to Consider a Different Tray or Mailer

Need end-crush protection instead?

Compare the FEFCO 0422. It uses the exact same roll-over locking mechanism, but applies it to the short end walls rather than the long side walls. This shifts the primary load path and changes how the flat blank nests during manufacturing.

Shipping directly in the mail?

Compare the FEFCO 0427. It includes an attached hinged lid that tucks closed, making it suitable for parcel networks without needing a separate outer box or shrink wrap.

Packing at high speeds?

Compare a glued tray like the FEFCO 0415. The 0424 requires manual folding. A glued tray pops open instantly or runs easily on automated tray erectors, saving significant labor on large fulfillment lines.

Close variants and lookalike dielines

The closest library neighbors include 0423, 0423a, 0423_1a. 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, Blank Footprint, and Assembly Labor

Board thickness and fold clearance

The 180-degree roll-over walls are highly sensitive to board thickness. Heavy double-wall board can cause the hinges to crack or prevent the locking tabs from seating in the base. Fine flutes usually fold the cleanest and lock the tightest.

Flat footprint and cutting layout

The extended roll-over flaps create a large, cross-shaped flat blank. This requires a larger initial sheet of corrugated board compared to a standard glued tray, trading material footprint for a glueless mechanical lock.

Assembly labor and pack-bench setup

Because the side walls must be rolled over the corner flaps by hand, this tray requires dedicated pack-bench labor. It is not compatible with linear gluing lines.

Outer closure requirements

As an open-top tray, the contents will spill if inverted. The packing route must include a separate lid, a shrink wrap station, or insertion into a master shipping carton.

Locking Tab and Clearance Adjustments

Locking tab clearance

The exact distance between the fold and the locking tabs can be adjusted to accommodate different board grades. This ensures the friction lock holds tight without tearing the slots when the board springs back.

Roll-over panel height

The inner wall can be sized to sit completely flush against the tray floor, or left slightly shorter to accommodate specific interior base pads.

Base slot width

The receiving slots in the base panel can be widened or narrowed to tune the friction fit, balancing secure retention against the physical effort required by the packer.

Board and packing details

Manual assembly sequence

Operators must fold the end walls first, fold the corner flaps inward, and then roll the side walls over them. Attempting to fold the side walls first will leave the corner flaps exposed and prevent the tray from locking.

Clearance and Locking Variants

FEFCO 0424a

A clearance-adjusted variant that alters the locking tab offsets and flap heights to accommodate specific board calipers, preventing the lock from popping open under tension.

Additional notes

Print surface and rolled edges

Because the side walls roll 180 degrees inward, the exterior print surface wraps over the top edge and down into the interior of the tray. This creates a premium look without requiring double-sided printing.

FAQs

Shipping and Route

Can I ship this tray through a parcel network?

Not on its own. Because it has an open top, the contents will spill. It requires a separate lid, a shrink wrap, or a master shipping carton for courier transit.

Closure and Assembly

Does this tray require tape or glue to stay together?

No. The side walls roll over the corner flaps and lock into slots in the base using mechanical friction. The tray holds its shape entirely through this interlocking design.

Board and Finish

What board types fit this structure?

Fine flutes and standard single-wall boards work well. Heavy double-wall boards are risky because the thick material binds and cracks when forced into a 180-degree fold.

Quantity and Production

How does the flat blank shape affect production?

The flat blank is shaped like a large cross with extended side flaps. This shape requires a larger overall sheet of corrugated board during manufacturing, which trades material efficiency for the glueless locking feature.

Can this be packed on an automated line?

Linear folder-gluers do not assemble this tray. It requires manual pack-bench assembly or specialized plunger-style tray erecting equipment.

Comparison

How does it differ from the 0422 tray?

The 0424 rolls its long side walls inward to lock the tray, providing lateral strength. The 0422 rolls its short end walls inward, providing longitudinal strength.

Inserts and Fit

Does the rolled edge interfere with custom inserts?

The rolled edge actually creates a clean, flush interior wall that supports inserts well. However, the internal dimensions must account for the double thickness of the side walls.

Closure and Assembly

Which walls should the packer fold first?

The packer must fold the short end walls and their attached corner flaps first. The long side walls are then rolled over those corner flaps to lock the tray.
