About this product

The EVF31020 is a premium folding carton tray designed for clean retail presentation and fast manual assembly. The long walls feature a pre-glued hem that hides the raw board edge, while the short walls roll over the corner gussets to lock the tray securely in place.

Because the long walls are glued at the factory, this tray ships flat but squares up quickly at the packing station without needing tape or adhesive.

Retail display and manual kitting jobs

Premium retail display

The pre-glued hem on the long walls ensures that the printed side of the board wraps over the top edge. This hides the raw paperboard edge and the unprinted interior, creating a finished look suitable for cosmetics, apparel, or specialty foods.

Fast manual kitting

For fulfillment centers building gift sets or multi-item packs, the pre-glued long walls and webbed corners make squaring the tray fast. The packer simply folds the short walls over the collapsed gussets to lock the shape, avoiding manual taping.

Multi-component gift sets

The rigid, double-thick long walls and locked corner gussets hold the tray's shape well when packed with multiple heavy or shifting items. This prevents the tray from bowing outward before it is placed into a master carton or presentation sleeve.

Shelf-ready open trays

When used as a secondary display tray on a retail shelf, the continuous graphic presentation over the hemmed edges provides a clean billboard for branding, while the friction-locked short walls withstand repeated customer handling.

Product categories relying on clean tray edges

Bakery and confectionery

The webbed corner gussets prevent crumbs or small items from slipping out of the bottom corners. While not liquid-tight, the continuous base-to-wall connection offers better containment than a standard slotted tray.

Apparel and soft goods

The smooth, double-thick top edges prevent snagging on delicate fabrics. The rigid corners hold the tray's shape well when stacked on retail shelves or placed inside a larger presentation box.

Cosmetics and personal care

For lightweight bottles, tubes, or jars, the clean edges and hidden flutes or raw paperboard align with premium branding expectations, especially when paired with a custom insert.

When to compare fully glued or corrugated trays

High-speed automated packing

This tray is designed for manual or semi-automated erection. The roll-over locking motion involves manual dexterity. If the packing line uses high-speed automated tray formers, a four-corner glued tray or a machine-erected lock-bottom tray may be a better fit.

Heavy industrial parts

The friction-lock tabs and folding carton board are meant for lightweight consumer goods. For heavy hardware or automotive parts, a corrugated tray with reinforced corners will provide better stacking strength and puncture resistance.

Board caliper, print surface, and packing line choices

Board caliper and foldability

This design relies on tight 180-degree folds for both the glued hems and the roll-over walls. It depends on a folding carton board that can handle these sharp creases without cracking. Thicker micro-flutes are generally too stiff for the roll-over lock to engage properly.

Outer shipping protection

As an open-top tray, this package is not meant for direct parcel shipping. It is often paired with a custom sleeve, a matching lid, or insertion into a master shipping carton to protect the contents during transit.

Print surface and coating

Because the long walls are glued flat to themselves, the interior coating or varnish should accept the manufacturer's cold glue. Heavily coated or UV-varnished interiors may need glue-assist knockouts.

Packing line setup

While the pre-glued long walls save time compared to fully unglued trays, the short walls still involve a manual roll-over motion. Buyers should evaluate whether their fulfillment team has the dexterity and time for this step compared to a fully glued pop-up tray.

Adjusting roll-over height and locking tabs

Roll-over wall height

The height of the inner roll-over panel can be adjusted. It should be long enough to securely trap the corner gussets, but it does not have to reach all the way to the floor of the tray.

Locking tab friction

The tabs that anchor the short walls into the base can be tuned based on the exact thickness of the chosen board. This ensures the walls snap into place securely without tearing the gussets or popping open.

Hem width on long walls

The depth of the pre-glued hem can be extended further down the inside of the long wall. A deeper hem provides more printed surface on the interior and increases the rigidity of the wall.

Packing details

Straight-line gluing route

The long walls are folded and glued flat by the manufacturer using straight-line folder-gluer equipment. This shifts the assembly labor away from the packing station, delivering a flat blank that is ready for immediate use.

Locking tab variations

Alternative locking geometries

Neighboring templates in this family offer different tab shapes and gusset cutouts, which can change how the lock feels during manual assembly. The choice often depends on the specific board grade being used.

Additional notes

Print surface and edge presentation

Because the long walls fold inward and glue flat, the exterior printed surface wraps over the top edge. This provides a continuous graphic presentation and hides the raw, unprinted edge of the paperboard.

FAQs

Does this tray need glue or tape to assemble?

The manufacturer pre-glues the long walls before shipping. At the packing station, the tray simply folds up and locks together using friction tabs on the short walls, without extra adhesive.

Can this tray be made from corrugated cardboard?

The 180-degree folds used for the glued hems and roll-over walls are generally too tight for corrugated flutes. It is designed for solid folding carton board like SBS or FBB.

Can I ship this tray directly in the mail?

This is an open-top presentation tray. To ship it through a courier network, it should be placed into a protective sleeve, a secure lid, or a corrugated outer shipper.

Are the corners completely sealed against leaks?

The webbed corner gussets provide excellent containment for powders or small items, but the tray is not hermetically sealed or liquid-tight.

How is the tray delivered to the facility?

It arrives flat. The manufacturer folds and glues the long walls during production, so the blank is ready for immediate manual erection without taking up excess storage space.

Why are the long walls pre-glued instead of rolling over like the short walls?

Pre-gluing the long walls reduces the manual folding steps at the packing station. It also provides a clean, double-thick edge without adding too much bulk to the flat blank.

Will the locking tabs pop open during handling?

When properly matched to the board caliper, the tabs create a secure friction lock. If the board is too thick or too stiff, the tabs may struggle to engage, which is why prototypes help verify the fit.

Can the printed design continue onto the inside of the tray?

Because the long walls fold inward and glue flat, the exterior printed surface wraps over the top edge, providing a continuous graphic presentation on the upper interior.
