High-Volume Palletized Distribution
High-speed produce and agricultural packing
The open top allows field heat to escape, while the interlocking tabs keep dense pallets of fruit or vegetables from shifting during transit. Because it is machine-erected, it keeps up with high-throughput sorting lines.
Commercial bakery and confectionery transport
The rigid top flanges prevent the tray above from crushing delicate baked goods. Trays can be moved directly from the delivery truck to the retail floor without unpacking.
Heavy industrial parts staging
The glued corners and flanged walls contain heavy components securely. The open top allows assembly workers to access parts quickly without opening flaps or cutting tape.
Direct-to-floor retail display
Club stores and bulk grocery locations often move unitized pallets straight from the truck to the aisle. The open top provides immediate product visibility for shoppers.
Agriculture, Commercial Bakery, and Industrial Parts
High-throughput packing facilities
Operations that process thousands of units a day cannot afford the labor of manually folding complex trays. This design shifts the work to a machine, trading a capital equipment requirement for massive labor savings and lower per-unit board usage.
Cold chain and grocery distribution
When manufactured with moisture-resistant board, the tray maintains its stacking strength in refrigerated environments. The interlocking tabs ensure the pallet remains stable even if individual trays soften slightly from humidity.
Automated fulfillment centers
Facilities equipped with hot-melt tray formers use this design to standardize their outbound pallet loads. The consistent tab placement allows robotic palletizers to stack the trays accurately.
When to Consider Manual or Closed Packaging
Hand-packing operations without tray erectors
If you do not have automated hot-melt machinery, this tray cannot be assembled efficiently. Compare the base FEFCO 0436 or FEFCO 0432, which use 180-degree roll-over walls to lock together manually without glue.
Single-parcel courier shipping
The open top leaves contents exposed. If you are shipping directly to a consumer through a parcel network, compare a fully enclosed mailer or plan to place this tray inside a master carton.
Board Thickness, Machine Clearances, and Pallet Fit
Tray erector compatibility
The exact placement of the corner glue flaps must match your machine's forming mandrel and plow clearances. Sharing your equipment model early ensures the flat blank will run without jamming.
Board grade and tab clearance
Moving to a thicker double-wall board increases vertical crush resistance, but it also changes how the tabs fit into the receiving slots. The die-cut slots must be widened to accommodate the thicker material, or the trays will fail to interlock.
Pallet pattern alignment
The length and width of the tray must be sized to fit your specific pallet dimensions without overhang. Overhanging trays lose the structural support of the interlocking tabs.
Moisture and humidity exposure
If the tray will move through cold-chain environments or carry damp produce, the board should be treated to resist moisture. Standard kraft board will absorb humidity and lose the rigidity required for the interlocking tabs to function.
Adjusting Flanges, Tabs, and Ventilation
Flange width and stacking surface
The width of the top shoulder can be adjusted. A wider flange provides a larger resting surface for the tray above, increasing stability, but it reduces the open area available for product loading and display.
Ventilation and hand holes
The end panels naturally accommodate die-cut hand holes for easier lifting. Additional ventilation cutouts can be added to the side walls for produce, though this slightly reduces the overall vertical compression strength.
Tab and slot profiles
The height and width of the alignment tabs can be modified to match specific palletizing equipment or to provide deeper interlock for loads with a high risk of lateral shift.
Board and packing details
Managing internal stripping waste
The interlocking base slots create small pieces of scrap board during die-cutting. For high-volume runs, the converter must aggressively manage this internal stripping to prevent press jams and ensure clean slots for palletizing.
Glued vs. Manual Tray Variants
FEFCO 0436.2 (Lidded Glued Tray)
Adds crossed interior top flaps and a front tuck tab over the glued base, providing a closed top for environments that require overhead protection.
Additional notes
Hot-melt glue specifications
The speed of your packing line dictates the required hot-melt adhesive. The glue must set fast enough to hold the corners square immediately after the tray leaves the forming cavity.

FAQs
Assembly and Machinery
Can this tray be assembled by hand?
No. While it is physically possible to fold and glue the corners manually, the 90-degree flaps are specifically designed for the speed and compression plates of an automated hot-melt tray erector. Hand assembly will be slow and likely result in out-of-square trays that fail to stack.
Stacking and Palletizing
How do the interlocking tabs work?
The short end walls feature upward-pointing tabs that protrude above the tray. The bottom of every tray has corresponding die-cut slots. When stacked, the tabs of the lower tray lock into the slots of the upper tray, preventing the pallet load from shifting laterally.
Shipping and Route
Can I ship this tray through a parcel network?
Because the top is open and the contents are exposed, single-parcel courier routes require placing this tray inside a fully enclosed master carton to keep contents secure.
Board and Fit
Can we use heavy double-wall board for more strength?
Double-wall board provides excellent vertical compression strength for heavy loads. However, the die-cut slots and fold allowances must be precisely recalculated to handle the extra thickness, otherwise the interlocking tabs will bind or crush during stacking.
Customization
Can we change the size of the top flanges?
The top flanges can be widened to create a larger resting ledge for the tray above, or narrowed to increase the open display area. This decision balances your need for stacking stability against the size of the product being loaded.
Production Path
Does this tray require a cutting die?
The specific alignment tabs, receiving slots, and top flanges require flatbed or rotary die-cutting. It cannot be produced on a standard box-making slotter without a cutting die.
Print and Branding
What surfaces are available for printing?
The flat blank allows standard flexographic or lithographic printing on the outer side and end walls before the machine erects the tray.
Prototyping
How do we test the tab interlock before a full production run?
Digital cut prototypes can verify the tab and slot clearances with your specific board grade, ensuring the trays will stack correctly before committing to a full run.
