EVC30021

Glued Stacking Tray with Bench Supports

The EVC30021 is a corrugated tray used for automated packing. It features folded corner ledges, known as bench supports, that provide a flat, load-bearing surface for stacking. This allows heavy or delicate goods to be palletized without the upper trays resting directly on the contents below.

Because it relies on glued corner seams rather than friction locks, this tray is usually erected by machine at the packing facility. It is a practical fit for agricultural produce, retail-ready displays, and open-top applications where vertical stacking strength is a priority.

Produce and Retail Display

Agricultural and Produce Packing

The open top provides ventilation for fresh goods, while the reinforced bench corners carry the weight of the trays stacked above. This keeps delicate produce from bearing the vertical load during transit.

Retail-Ready Shelf Displays

With lowered front and back walls, the tray allows immediate product visibility on the shelf. The glued corners keep the tray rigid even when customers remove items, making it an efficient shelf-ready format.

Heavy Parts Distribution

For industrial components that do not need a closed top, the bench supports provide the vertical strength to stack heavy items on pallets without crushing the lower layers.

Ventilated Cold-Chain Transport

When paired with appropriate moisture-resistant board, the open design allows cold air to circulate freely around the product, making it useful for temperature-controlled distribution.

Automated Packing and Palletized Distribution

Automated Packing Facilities

This tray is built for mechanization. It ships flat to the facility and is usually erected by a tray former that folds the bench supports and applies adhesive to the corner flaps efficiently.

Palletized Distribution Networks

The interlocking tabs and base slots help keep columns aligned on a pallet. This is particularly useful when moving tall stacks of open trays through distribution centers.

Retail Replenishment

For fast-moving consumer goods, the tray moves directly from the pallet to the retail shelf. The open top and lowered walls reduce the labor needed to unpack and display the product.

When to Consider Friction-Locked Trays

Manual Packing Operations

If automated gluing equipment is not available, a friction-locked tray is usually a better choice. Glued trays take more time to erect by hand because they need a fixture to hold the walls square while the adhesive sets.

Single-Unit Parcel Shipping

Because the top is completely open, this tray is not suited for mixed courier networks on its own. If the product ships directly to a consumer, compare fully enclosed mailers or plan to use this tray inside a master shipper.

Board Thickness, Tab Clearance, and Corner Profile

Board Grade and Stacking Tab Fit

The stacking tabs on the top edges should interlock smoothly with the slots on the base of the tray above. If a thicker board is specified for heavier produce, the slot widths and fold allowances should be recalculated to prevent the tabs from binding.

Moisture Resistance for Cold Chains

If the tray will move through refrigerated environments or high humidity, corrugated board and adhesives may weaken. Discuss moisture-resistant liners and appropriate glue during the quoting process to maintain stacking integrity.

Pallet Footprint and Corner Profile

The choice between 90-degree corners and angled beveled corners changes the tray's exact footprint. This profile should be matched to the existing tray-forming equipment and the planned pallet pattern to avoid overhang.

Manual Versus Automated Erection

Confirm whether the packing location has the equipment to apply adhesive and fold the bench supports efficiently. If manual assembly is planned, a different tray style may reduce labor time.

Hand Hole Sizing and Display Wall Height

Display Wall Height

The lowered central section of the long walls can be raised or lowered to balance product visibility with lateral containment. Lowering the wall exposes more of the product but reduces the tray's ability to absorb side impacts.

Hand Hole Dimensions

The integrated hand holes can be resized for different glove types or lifting weights. However, making the cutouts too large removes material from the short walls, which can reduce the overall vertical strength of the tray.

Stacking Tab Width

The width of the interlocking tabs can be adjusted based on the weight of the product and the expected lateral forces during transit. Wider tabs provide more resistance to shifting but need longer base slots.

Packing details

Tray-Former Compatibility

Because this tray relies on specific fold sequences for the bench ledges and tuck tongues, the blank is usually matched to the plow and glue gun layout of the specific tray-forming equipment.

Straight Versus Angled Corner Profiles

EVC30021 (Angled Corners)

The base design features beveled corners, which can change how the trays nest on a pallet and alter the corner crush dynamics.

EVC30021_1 (Straight Corners)

This variant uses 90-degree straight corners. It is functionally similar but changes the machine settings during erection.

Additional notes

Pallet overhang and tab alignment

Stacking tabs only function if the trays are aligned. If the pallet pattern requires cross-stacking or creates overhang, the tabs may not engage the base slots, reducing column stability.

FAQs

Does this tray use glue to stay together?

The long walls are typically glued to the corner dust flaps. It does not have mechanical friction locks to hold its shape, so it relies on adhesive.

Can this tray be assembled by hand?

While possible, it is generally slow. Manual assembly involves applying adhesive and holding the corners square until the bond sets. It is usually erected by tray formers.

How do the stacking tabs work?

The long walls feature protruding tabs on their top edges. When another tray is stacked on top, these tabs slide into corresponding slots cut into the base of the upper tray, helping to lock the column together and reduce lateral shifting.

What is the purpose of the bench supports?

The bench supports are horizontal ledges folded into the top corners. They provide a wide, flat resting surface for the tray above, transferring the vertical weight down through the corners rather than onto the product inside.

Can thicker board be used for this tray?

Thicker board is often used for heavy agricultural loads. However, the thicker material means fold clearances and base slots should be adjusted so the stacking tabs do not bind during palletization.

Is this tray used for ecommerce shipping?

The open top leaves the contents exposed. For parcel delivery, the tray should be placed inside a fully enclosed master carton.

Can the height of the long walls be changed?

The lowered central section of the long walls can be adjusted to show more of the product or raised to provide better lateral containment, depending on the retail display needs.

What is the difference between straight and angled corners?

The corner profile affects how the trays fit together on a pallet and how they interact with tray-forming equipment. The choice depends on the specific machinery and pallet pattern.

Review the product weight, pallet pattern, and available packing equipment to ensure this glued tray fits the production line.
