EVF41090

Concave Edge Retail Tray

The EVF41090 is a premium presentation tray defined by its sweeping, concave top edges and clean double-wall construction. Designed for high-end retail, bakery, and gift assortments, it elevates the product display while hiding all raw board edges inside the rolled walls.

Delivered flat and assembled entirely without glue, the tray uses webbed corner gussets and friction-locking inner panels to hold its shape. While the double-wall design requires more material and manual setup than a standard glued tray, the resulting structure offers a continuous, leak-resistant corner and a striking visual profile.

Presentation and Display Contexts

Premium Gift Hampers

The sweeping edges and double-thick walls create a high-value frame for assorted gifts, cosmetics, or specialty foods. The lack of glue seams keeps the presentation pristine.

Artisan Bakery and Confectionery

The webbed corner gussets fold inward, creating a continuous interior boundary that prevents crumbs or small dry items from escaping through the bottom corners.

Cosmetics and Skincare Sets

The double-wall thickness and sweeping edges frame small, high-value bottles or jars, while the friction locks keep the presentation clean without visible glue lines.

Apparel and Soft Goods

Rolled inner walls ensure no sharp paperboard edges catch on delicate fabrics, making it a safe display choice for folded accessories or boutique clothing items.

Retail and Bakery Applications

Boutique Retail

For brands prioritizing presentation over packing speed, this tray offers a distinctive shape that stands out on shelves and in display cases.

Manual Fulfillment Operations

Because the tray requires simultaneous folding of adjacent walls to web the corners, it is best suited for operations set up for hand-packing rather than automated lines.

Corporate Gifting Programs

The flat-shipping format allows large volumes to be stored efficiently, while the manual assembly can be done on-demand as gift sets are built.

Specialty Food Counters

The webbed corners provide a continuous barrier that helps contain dry goods, making it useful for open-top display of wrapped treats or dry snacks.

When to Consider Straight-Edge or Glued Trays

Flat Stacking Requirements

The concave top edges reduce the tray's ability to support flat top loads. If trays must be stacked directly on top of one another without an outer shipper, a straight-edge double-wall tray is a safer choice.

High-Speed Packing

The complex manual folding sequence makes this tray inefficient for high-volume, automated fulfillment. For faster setup, consider a pre-glued crash-lock or snap-bottom tray.

Board Choice and Assembly Planning

Board Folding Endurance

The design relies on 180-degree folds for the inner walls and diagonal creases for the corner gussets. Selecting a board with high folding endurance, such as Solid Bleached Sulfate (SBS) or Folding Boxboard (FBB), is critical to prevent cracking.

Print Surface Mapping

Because the inner walls roll over from the outside, the interior of the tray is formed by the same printed side of the board as the exterior. This allows for full inside-and-out graphics without requiring two-sided printing.

Outer Shipping Strategy

Because the concave edges do not support flat top loads and the tray is open, a separate lid, sleeve, or master shipper must be planned for transit.

Assembly Labor Allocation

The webbed corners require adjacent walls to be folded simultaneously before the inner walls roll over. This sequence takes more time than a standard snap-lock tray and must be factored into packing costs.

Adjusting the Concave Profile and Corners

Concave Curve Depth

The depth of the sweeping top edge can be adjusted. A shallower curve provides more wall height for containment, while a deeper curve creates a more dramatic display profile.

Corner Profile Style

The outer corners can be adjusted to a chamfered, flat, or extended profile to match specific branding or fit within a custom outer sleeve.

Inner Wall Height

The depth of the inner rolled wall can be modified to change the friction lock tension or accommodate different base inserts.

Packing details

Blank Footprint and Material Usage

The double-wall construction and webbed corners require a larger flat blank than a standard single-wall tray. This increases material usage per unit, which is partially offset by removing the gluing step.

Additional notes

Board thickness and friction locks

The friction locks that hold the tray together are calibrated to the specific thickness of the board. If you change board grades later, the template clearances must be updated to ensure the tray stays locked.

FAQs

Can this tray be erected by automated machinery?

The webbed corners require adjacent walls to be folded simultaneously, followed by rolling the inner walls over the gussets. This sequence is designed for manual assembly.

Is the tray liquid-tight?

While the continuous webbed corners prevent dry items and crumbs from leaking, the folded paperboard construction is not sealed for liquids.

Can this tray be shipped through parcel networks?

As an open-top display tray, it requires a separate lid, sleeve, or outer shipping box to protect the contents during transit.

Can I use recycled board or micro-flute corrugated?

Recycled board may crack on the complex diagonal folds, and micro-flute is generally too thick for the 180-degree roll-over walls. High-quality folding carton board is a safer choice.

Do I need two-sided printing to have graphics on the inside?

The inner walls are formed by rolling the outer panels inward, meaning the primary printed side of the flat blank becomes both the exterior and interior of the finished tray.

Can the sweeping edge be made deeper?

The depth of the concave curve can be adjusted prior to production. However, making it too deep reduces the effective wall height and may compromise product containment.

Can I use a custom insert with this tray?

A die-cut paperboard or foam insert can rest on the flat base panel. The friction-locked inner walls provide a rigid boundary to hold the insert securely in place.

Should I request a physical sample before ordering?

Because the friction locks and 180-degree folds are sensitive to board thickness, a physical prototype is strongly recommended to verify assembly and corner integrity.
