About this product

The EVF31955 is an open-top paperboard tray featuring smooth, rounded corners and outward-tapering walls. Instead of sharp 90-degree creases, the corner flaps curve to create a continuous transition between the side and end panels.

Because the walls taper outward, fully assembled trays can nest deeply inside one another. This makes the format highly efficient for fast-paced packing lines, though the rounded corners often rely on specialized tray-forming equipment to assemble.

Common uses

Bakery and pastry assortments
Premium catering and prepared foods
Retail gift assortments wrapped in film

Premium Presentation and High-Volume Packing

Bakery and food service presentation

The rounded corners offer a softer, higher-end look than standard folded trays, making this a strong fit for pastries, prepared foods, and catering. The open top provides immediate access, while the nested delivery keeps the packing station organized.

Premium retail assortment trays

When used inside a larger setup or wrapped in film, the conic corners distribute impact better than sharp edges and provide an uninterrupted surface for branding.

Produce and fresh food packing

The tapered walls allow airflow when trays are nested or stacked in crates, while the open top provides clear visibility for fresh goods.

Catering and event serving

The rigid glued base and rounded corners make the tray comfortable to handle during events, offering a sturdy platform for passing assortments.

Food Service, Bakery, and Retail Display

High-speed fulfillment lines

Packers can pull individual trays from a nested stack with one hand, eliminating the need to manually fold or erect boxes at the station. This relies on the converter supplying the trays pre-formed or the facility operating its own tray former.

Retail shelf display with film wrap

When the tray is flow-wrapped or shrink-wrapped, the rounded corners reduce the risk of puncturing the film compared to sharp 90-degree tray corners.

Centralized commissary kitchens

Facilities can form the trays centrally, nest them efficiently, and ship them to satellite locations or packing stations ready for immediate filling.

When to Consider Flat-Shipping or Straight-Wall Trays

Flat-shipping requirements

Because this tray lacks diagonal collapsing scores, it cannot be shipped flat after gluing. If warehouse space is tight and on-site tray forming is not an option, compare this to a standard four-corner glued tray that ships flat and pops open.

Heavy vertical stacking

Tapered walls do not support heavy top loads as well as straight vertical walls. If the trays will be stacked high without an outer master carton, a straight-sided tray or a structural lid may be necessary.

Assembly Route and Nesting Pitch

Pre-glued nesting versus on-site forming

Buyers should decide whether to receive these trays flat (requiring a specialized tray former at the packing facility) or pre-glued and nested by the converter. Nested delivery saves packing labor but increases inbound freight volume.

Board grade and corner cracking

The board should be flexible enough to curve around the corner radius without cracking the outer liner or print finish. Thick boards or heavy coatings should be tested on the specific corner geometry.

Taper angle and nesting depth

The outward slope of the walls dictates how tightly the trays nest. A steeper angle allows deeper nesting but reduces the internal floor space for the product.

Coating and moisture resistance

For food applications, check if a poly-coating or grease-resistant board is needed, and verify that the chosen adhesive will bond securely to that specific coating.

Taper Angle and Corner Radius

Corner curvature

The radius of the rounded corners can be adjusted to create a tighter or softer curve, provided it matches the available forming die and does not exceed the base dimensions.

Wall taper angle

The outward slope of the walls can be modified. Steeper angles improve nesting density, while shallower angles maximize the flat floor area.

Base dimensions

The length and width of the floor can be scaled to fit specific product counts, keeping in mind that the top opening will always be larger due to the taper.

Packing details

Print continuity on corners

The smooth conic corners provide a continuous surface that is excellent for wrap-around graphics, avoiding the visual break caused by sharp folded edges.

Specifying the Taper

EVF31955a (Delta Taper)

Produces the exact same physical tray, but allows the buyer to specify the taper by the difference in width between the top opening and the bottom base, rather than specifying a degree angle.

Additional notes

Tray former tooling requirements

Automated assembly requires a plunger and die matched exactly to the tray's base dimensions, corner radius, and taper angle.

FAQs

Can these trays be assembled by hand?

While possible for very small sample runs, manual assembly is highly inefficient. The rounded corners need to be held in tension while the adhesive sets, making this format heavily dependent on automated tray-forming equipment.

Do these trays ship flat?

They ship flat only if the packing facility has the machinery to form and glue them. Otherwise, the converter usually forms them and ships them to the packer in nested stacks.

Are these trays suitable for heavy items?

The tapered walls are designed for nesting, not for bearing heavy vertical weight. They work best for lighter items like baked goods or when packed inside a rigid master carton.

Will the board crack on the rounded corners?

The risk of cracking depends on the board thickness, grain direction, and the tightness of the corner radius. A prototype should be tested to ensure the chosen material curves smoothly.

Can I ship this tray through a parcel network?

This is an open-top primary container. It needs an outer shipping box or sleeve to contain products securely during courier or parcel delivery.

How does the taper affect my product fit?

The internal floor of the tray is smaller than the top opening. Products should be sized to fit the bottom footprint, not just the top rim.

Can I use window film with this tray?

Because it is an open-top tray, it does not have a top panel for a traditional window patch. Products are typically displayed open or the entire tray is flow-wrapped in clear film.

How do I specify the taper for my order?

You can specify the taper either by the angle of the walls (e.g., 20 degrees outward) or by the difference in width between the top opening and the bottom base.
