About this product

This unglued corrugated tray features hollow, rectangular "benches" along two opposite sides. These rolled edges create built-in standoffs, crush zones, or presentation frames without requiring separate inserts.

Because the extended side panels require a large flat blank and manual folding, this style is typically reserved for premium retail presentations, electronics kitting, or protective inner packaging where the side framing does real mechanical or visual work.

Common uses

Electronics kitting requiring side impact zones.
Retail displays needing a wide frame for branding.
Heavy component packing where the product needs to be centered.

Protective and Presentation Uses

Protective Inner Packaging

The hollow side benches act as shock-absorbing crumple zones for electronics or heavy components. When placed inside a master shipper, the benches keep the primary item centered and away from the outer impact zones.

Retail Presentation and Kitting

The wide top ledges frame the central product, providing a premium unboxing experience. The horizontal surfaces offer a continuous area for branding, labeling, or printed instructions that face the user immediately upon opening.

Heavy Component Centering

For heavy motors or industrial parts, the hollow benches act as physical spacers, keeping the dense item centered and preventing it from shifting against the outer box walls.

Multi-Part Assembly Kits

The wide ledges visually separate the primary component from smaller accessories or cables packed alongside it, organizing the presentation.

Common Packing Situations

Electronics and Component Kitting

Teams packing sensitive equipment use the side standoffs to isolate the product from the edges of the outer box. The hollow benches provide a physical buffer without needing loose void fill.

Premium Retail Display

Brands use the wide bench ledges to elevate the perceived value of the product. The framing effect draws attention to the center of the tray, making it a strong choice for high-end consumer goods.

Industrial Spare Parts

When shipping heavy or awkward replacement parts, the side standoffs help center the item inside a master carton, ensuring the weight is distributed evenly during transit.

When to Consider a Different Tray

When board efficiency is the priority

The extended panels required to form the benches create a large, cross-shaped flat blank with considerable offcut waste. If the product does not strictly need the wide horizontal standoff, a standard roll-end tray uses far less board and is faster to fold.

When heavy items will rest on the benches

The inner vertical walls of this specific tray only drop down at the corners. The center span of the bench is an unsupported bridge. If your packing setup requires stacking heavy items directly on the bench ledges, a tray with a continuous inner support wall should be evaluated instead.

When the tray ships without an outer box

This tray has an open top. If the package must travel through a courier network on its own, a roll-end tray with an attached locking lid provides the necessary closure.

Key Configuration Choices

Bench Width and Product Clearance

The width of the side benches dictates how much central space remains for the product. Wider benches increase the overall blank size, and they must be sized carefully so they do not overlap in the center of the tray.

Board Thickness and Locking Friction

The base slots are cut to match the exact board caliper. Changing from a thin E-flute to a thicker B-flute requires adjusting the die to ensure the locking tabs fit securely into the base without tearing the liner.

Master Carton Sizing

Because the hollow benches add considerable width to the tray, the overall footprint is larger than the product itself. The outer master carton must be sized to accommodate this expanded footprint.

Flute Profile Selection

Thinner flutes fold crisply for the complex roll-over sequence. If a thicker flute is chosen for added crush resistance, the locking tabs and slots must be carefully adjusted to prevent binding.

Template Adjustments

Bench Width Adjustment

The horizontal standoff can be widened to create a larger display frame or a deeper crush zone, provided the two sides leave enough room for the central payload.

Inner Wall Edge Chamfering

The edges of the inner drop-down walls can be chamfered. This small adjustment prevents the inner walls from binding against the corner dust flaps during manual assembly, speeding up the packing process.

Dust Flap Length

The length of the corner dust flaps determines how far the inner wall segments extend along the bench. Adjusting this length changes the amount of corner support the bench receives.

Packing details

Center Span Load Limits

To allow the tray to fold correctly, the inner vertical walls only drop down at the corners to trap the dust flaps. The center span of the bench ledge lacks vertical support underneath. It is designed for side-impact protection and visual framing, not for bearing heavy direct point loads.

Blank Size and Board Yield

The extended roll-over panels create a large, cross-shaped blank. This geometry reduces the number of trays that can be nested on a single corrugated sheet, increasing the overall board usage compared to standard trays of the same footprint.

Additional notes

Print surface on the benches

The wide, flat top of the side benches provides an excellent continuous billboard for branding, instructions, or labeling that faces the user immediately upon opening the outer carton.

Sample testing for lock friction

Because the locking tabs rely on friction, a physical prototype in the exact production board helps verify that the tray holds together tightly without tearing during assembly.

FAQs

Can this tray be shipped on its own?

No, it has an open top. It is designed as an inner protective tray or retail display and requires an outer master carton or a custom lid for parcel or courier shipping.

Does it require glue or tape to assemble?

No. The tray relies on a mechanical roll-end lock. The long walls roll over the side dust flaps, and tabs lock securely into slots in the base panel.

Can the side benches support heavy items resting on top of them?

The center of the bench ledge is unsupported underneath. While the corners are strong, heavy point loads in the middle of the bench may cause the corrugated board to bow or crush.

Why does this tray use more material than a standard tray?

The panels that form the hollow benches extend far out from the base, creating a large, cross-shaped flat blank. This shape leaves more unused offcut waste on the corrugated sheet during die-cutting.

Can this be erected on automated packing lines?

This specific roll-over and tab-locking sequence is designed for manual assembly at a packing station. It is a poor fit for automated folder-gluers.

Which flute profiles fit this folding sequence?

Thinner profiles like E-flute provide crisp folds for the complex roll-over benches and locking tabs. Thicker flutes can be used but require precise die adjustments to ensure the tabs fit into the base slots without cracking.

Can I place smaller components inside the hollow benches?

The hollow benches are sealed once locked, so they cannot be used as storage compartments for smaller items or accessories.

What happens if the locking tabs are not pre-folded?

The locking tabs must be pre-broken before rolling the bench over. If they are not pre-folded, they can crush against the base panel instead of seating into the slots, preventing the bench from locking.
