About this product

The EVF31950 is a glued, tapered paperboard tray designed for high-speed fulfillment. It is delivered completely flat and snaps into a rigid, outwardly angled shape when the operator pushes the opposite corners inward.

Because the converter pre-glues the complex split corner flaps, this tray eliminates manual folding and taping at the packing station. The tapered walls offer clear product visibility for retail kitting and bakery applications, though they are usually paired with an independent lid or outer shipper if the packed trays need to be stacked.

Common uses

Bakery and pastry packing.
Food service for wrapped items.
Retail kitting and assortment presentation.
Lightweight parts staging.

Products And Packing Setups For The Collapsible Tapered Tray

High-speed retail kitting and assortment packing

The quick snap-open assembly makes this tray practical for packing lines where operators need to load multiple components quickly. The tapered walls guide items into the base and keep the contents visible for retail display.

Bakery and dry food service

Often used for pastries, wrapped baked goods, or lightweight food service items. The tray provides a clean presentation profile, though it is not liquid-tight and should be paired with appropriate food-safe boards and liners.

Lightweight parts staging

Useful in assembly or kitting environments where small components need to be gathered and moved. The tapered walls allow empty trays to nest, saving space on the workbench before loading.

Apparel and soft goods presentation

Provides an open, accessible display for folded garments or accessories. The angled walls frame the product well for unboxing experiences when placed inside a larger mailer.

Fulfillment And Retail Environments

Fast-paced manual fulfillment

Because the complex corner gluing is handled during manufacturing, the packing station only needs to apply inward pressure to snap the tray into its 3D shape. This reduces the time spent erecting trays compared to unglued, interlocking styles.

Retail display and shelf presentation

The outward lean of the walls creates a wider opening at the top, making it easier for customers to see and reach the product. This is especially useful for assortments or multi-pack items.

High-volume bakery operations

For bakeries moving large quantities of dry or wrapped goods, the flat delivery and quick setup keep the packing line moving without the bottleneck of manual folding.

When To Consider A Different Tray Style

Heavy stacking or vertical load requirements

Tapered walls deflect downward forces poorly. If the trays will support the weight of pallets or heavy stacked goods without an outer master carton, a straight-walled tray or a design with reinforced corner posts is a safer choice.

Wet or liquid-heavy foods

The corners of this tray feature physical cuts to allow the split flaps to fold flat. It is not a leak-proof folded-web tray. If you are packing items with high moisture or liquid content, consider a continuous-corner web tray instead.

Board, Taper, And Outer Packaging Choices

Board thickness and snap-open performance

The tray relies on diagonal creases in the corner flaps acting as hinges. If the paperboard is too thick, these hinges can bind or crack, preventing the tray from snapping open smoothly. Standard folding boxboard (FBB) or solid bleached board (SBB) usually performs best, while heavier calipers may need physical prototyping.

Outer shipping and master cartons

As an open-top tray with angled walls, this package offers no top crush protection. It is typically used as an inner primary package that is later loaded into a corrugated master shipper for transit.

Print surface and branding

The tapered walls mean both the inside and outside surfaces are clearly visible to the end user. Discuss whether the board should be coated on one or both sides depending on your branding goals.

Packing line space and staging

While the trays ship flat, fully erected trays can nest inside one another. This allows operators to snap open a batch of trays and stage them efficiently before loading begins.

Adjusting The Tray Geometry

Wall taper angle

The outward lean of the walls (typically around 20 degrees) can be adjusted to change the presentation angle or footprint. Extreme angles should be checked to ensure the corner flaps do not collide during the automated folding and gluing process.

Base dimensions and footprint

The length and width of the flat base can be scaled to fit specific product arrangements or to match the internal dimensions of a master shipping carton.

Wall height and product containment

The depth of the tray can be increased for taller items, though taller walls combined with a steep taper will increase the overall footprint of the erected tray.

Packing details

Nesting empty trays

While the tray is designed to ship completely flat, the tapered walls do allow fully erected trays to nest inside one another if they need to be staged temporarily on the packing floor.

Additional notes

Grain direction and folding action

The grain direction of the paperboard should typically run parallel to the long walls to ensure the longest spans remain rigid and the collapsing hinges operate smoothly.

FAQs

Does this tray require any gluing or taping at the packing station?

No. The complex split-flap corners are glued during the manufacturing process. The tray arrives flat and simply snaps into its rigid shape when the opposite corners are pushed inward.

Can this tray hold liquids or wet foods?

No. The corners have physical cuts that separate the flaps from the short walls, meaning the tray is not liquid-tight. It is best suited for dry goods, wrapped items, or products in secondary liners.

Can I ship this tray through a parcel network?

Not on its own. The open top and tapered walls provide no crush protection. It should be placed inside a corrugated outer box or mailer for parcel shipping.

Can I use a very thick board for extra strength?

Thick boards can cause the diagonal corner creases to bind, which prevents the tray from snapping open smoothly. If you need a heavier caliper, we recommend requesting a physical sample to test the folding action before committing to a full run.

Can the angle of the tapered walls be changed?

Yes. The wall angle can be adjusted to create a wider or narrower opening. However, extreme angles should be checked to ensure the corner flaps still fold correctly on the manufacturing equipment.

How is this tray delivered and stored?

The trays are delivered completely flat (knocked down). This saves space during transport and warehouse storage prior to use.

Can these trays be nested once assembled?

Yes. Because of the outwardly angled walls, fully erected empty trays can be nested inside one another, which is helpful for staging on a busy packing line.

What kind of printing works well on this tray?

Because the tapered walls expose both the interior and exterior, many brands choose to print on both sides. Standard offset or digital printing works well, provided the chosen paperboard supports it.
