About this product

The EVF31941 is an open-top folding carton tray with outwardly angled walls. Because the walls taper outward, fully erected trays can nest inside one another, making this a practical choice for high-volume packing stations, food service counters, and retail bins.

This tray relies on adhesive at the four corners. It can be supplied pre-glued and nested by the converter, or delivered flat for assembly on automated tray-forming equipment.

Common uses

Quick-serve food
Bakery and catering
Retail dump bins for small items
Produce trays

Practical Uses for Tapered Trays

Quick-Serve Food and Bakery

The open top and nested delivery make this tray well-suited for fast-paced food environments. Staff can pull a pre-glued tray from a stack and load it instantly. When specified with barrier-coated board, it handles grease and moisture effectively.

Retail Bins and Displays

Used as a simple dump bin or shelf tray for loose items. The tapered walls provide good visibility of the contents, though the open top means it cannot be stacked directly on top of other loaded trays.

Catering and Event Serving

For events where large volumes of food are prepared in advance, nested trays save counter space. The glued corners provide a clean presentation without visible interlocking tabs.

Produce and Farm Stand Trays

When packed with fresh produce, the open top allows for ventilation and easy inspection. The tapered design helps when transporting empty trays to the field or packing shed.

Industry and Packing Environments

High-Volume Packing Lines

For operations with automated tray formers, these trays are delivered flat. The simple four-corner glue design works well with common forming machinery, allowing rapid, on-demand assembly.

Manual Packing Stations

If you lack automated forming equipment, these trays are typically supplied pre-glued and nested. While shipping nested trays requires more logistics volume than flat blanks, it eliminates assembly labor on your floor.

Retail Shelf and Countertop Space

The outward taper means the top opening is wider than the base. When planning shelf layouts, consider the top dimensions to ensure trays fit side-by-side without overlapping.

When to Consider Straight Walls or Mechanical Locks

Maximizing shelf footprint with straight walls

If you need to maximize internal volume within a strict rectangular footprint, or if the trays should sit flush against each other on a shelf, compare this to a straight-walled glued tray. Straight walls will not nest.

Manual assembly without adhesive

If you need flat delivery but do not have a tray former or the ability to apply adhesive, consider a mechanical snap-lock tray. Snap-lock designs use interlocking tabs instead of glue, allowing manual assembly.

Adding top protection for parcel transit

This is an open tray with no lid and limited vertical crush resistance. It is not designed for standalone parcel transit and usually needs an outer shipper for courier networks.

Delivery, Board, and Taper Decisions

Nested delivery versus on-site machine forming

Decide whether you will receive the trays pre-glued and nested, or flat. Nested delivery saves packing labor but increases shipping volume. Flat delivery is dense and cost-effective but relies on a tray-forming machine to apply adhesive and erect the tray.

Barrier coatings for food and moisture

For food applications, specify whether the board needs grease or moisture resistance. The board caliper (thickness) should also be balanced with the tray size to ensure the base does not bow under the product's weight.

Interior versus exterior print surfaces

Because the tray is open, the interior is clearly visible. Consider whether you need printing on the inside panels, the outside walls, or both.

Taper angle and footprint balance

The outward taper increases the overall footprint of the tray. You should balance the need for deep nesting against the available shelf or counter space.

Adjusting the Taper and Flaps

Wall angle and nesting depth

The outward angle of the walls (defaulting to 105 degrees) can be adjusted. A steeper angle increases the footprint but allows trays to nest more deeply. The angle should be matched to the board thickness so nested trays pull apart smoothly without jamming.

Glue flap surface area

The triangular glue flaps on the short ends can be resized to provide more or less surface area for the adhesive, depending on the tray depth and the forming equipment used.

Corner radius on glue flaps

The rounded corners on the triangular glue flaps can be adjusted. This helps prevent the flaps from catching or tearing during high-speed machine assembly.

Packing details

Board caliper and nesting friction

When specifying thick boards or heavy coatings, the taper angle may need to be widened slightly. If the angle is too tight for the material, nested trays can create a vacuum or friction lock, slowing down the packing line.

Additional notes

Board thickness and nesting behavior

If you change to a thicker board, the taper angle should be reviewed. Thicker materials may require a slightly wider angle to ensure the trays do not wedge together tightly when nested.

FAQs

Do these trays arrive flat or already assembled?

It depends on your setup. They can be glued by the manufacturer and shipped to you nested (stacked inside each other), or they can be shipped flat if you have a tray-forming machine to erect and glue them on-site.

Can these be assembled by hand without a machine?

While possible, it is often slower than using mechanical locks. Because the tray relies on adhesive at the corners, manual assembly involves applying glue or double-sided tape to each flap. If you need manual assembly, a mechanical snap-lock tray is usually a better choice.

Are these trays safe for direct food contact?

The structure is widely used for food, but food safety depends entirely on the board and adhesive you select. You should specify a barrier-coated board and food-safe adhesive for direct contact.

Can the angle of the walls be changed?

Yes. The taper angle can be adjusted. A wider angle allows the trays to nest more deeply, which saves space, but it also increases the overall footprint of the tray.

Can I ship products in this tray through the mail?

Not on its own. This is an open-top tray designed for presentation, serving, or holding items inside a larger box. It offers no top protection and needs a sturdy outer shipper for courier networks.

Where does the glue go on this tray?

The short end walls have triangular flaps that fold inward. Adhesive is applied between these flaps and the inside of the long side walls to hold the tray's shape.

How does board thickness affect nesting?

Thicker boards take up more space when stacked. If you use a very thick board, the taper angle may need to be widened slightly so the trays do not wedge together tightly when nested.

Can I print on the inside of the tray?

Yes. Because the tray is open, the inside is highly visible. Many food service and retail applications print branding or instructions on the interior panels.
