EVF41001

Unglued Roll-End Tray with Pinch Locks

The EVF41001 is a flat-delivered paperboard tray that forms its shape without adhesive. It features single-thickness long walls to keep material usage efficient, while the short walls roll over themselves to create clean presentation edges and trap the corner dust flaps.

Because it relies on mechanical pinch locks in the base panel rather than glue, this tray is erected by hand at the packing station. It is a strong fit for bakery, apparel, and light retail kitting where an open-top presentation is useful, or where a separate lid or sleeve will be added later.

Retail Presentation and Kitting Uses

Open-top retail presentation

The double-wall short ends provide a clean, finished edge that looks professional on a retail shelf. The single-wall long sides keep the overall footprint compact and reduce material waste.

Base tray for sleeves and lids

This tray is frequently used as the base for a two-piece package. Once loaded, it can slide into a custom printed sleeve or take a separate lid for final sale.

Countertop display kitting

For lightweight point-of-purchase items, the tray organizes small goods effectively. The unglued design allows stores to set up the display quickly without tools.

Inner sorting tray for master cartons

When multiple product sets share a single outer shipper, these trays help separate components. The flat delivery keeps storage space low before the sorting process begins.

Bakery, Apparel, and Retail Contexts

Bakery and confectionery packing

A common unglued tray for light baked goods and sweets. It sets up quickly on a prep counter and is often paired with a food-safe liner or wrap.

Apparel and soft goods presentation

Provides a structured but lightweight base for folded garments, keeping them organized before an outer wrap or mailer is applied.

Cosmetics and personal care kitting

Useful for grouping lightweight bottles or tubes. The clean rolled edges frame the products well, especially when paired with a custom insert.

When to Consider a Different Tray Style

Automated packing lines

This tray relies on manual folding and friction locks. If the packing line uses automated folder-gluers or tray erectors, a machine-erected glued tray is usually a better choice.

Heavy payloads and long-wall bowing

The single-thickness long walls and base-panel pinch locks are designed for light to medium payloads. Heavy items may cause the long walls to bow or the locks to slip during transit.

Board, Print, and Packing Choices

Board thickness and lock tension

The D-shaped cutouts in the base and the creases for the roll-over panels are sensitive to board thickness. Changing the material caliper means updating the template to ensure the locks hold tension without tearing.

Print visibility on interior panels

Because of how the tray folds, the inside of the long walls will display the unprinted back of the board, while the inside of the short walls will display the primary printed side. Artwork should be planned accordingly.

Grain direction for roll-over panels

To prevent the board from cracking when the short walls fold 180 degrees over the dust flaps, the grain direction should run parallel to the short walls.

Outer closure and shipping route

As an open-top tray with friction locks, it is not meant for standalone parcel shipping. If the product will travel through a courier network, an outer mailer or secure shipping box should be planned.

Template Adjustments Beyond Dimensions

Lock cutout tuning

The width and depth of the pinch locks can be adjusted to match the specific friction and tear resistance of the chosen board grade.

Wall height proportions

The depth of the tray can be increased for taller products, though very tall single-thickness long walls may lose rigidity without heavier board.

Dust flap extensions

The corner dust flaps can be extended to provide more overlap inside the roll-over panels, which can help square the corners on larger trays.

Packing details

Manual assembly sequence and corner locking

Proper assembly involves folding the long walls up first, turning the dust flaps inward, and then rolling the short walls over the flaps to lock into the base. Attempting to fold the short walls first will prevent the corners from locking.

Additional notes

Flat delivery and storage space

Because the trays ship flat and use no glue, they take up very little space in the warehouse before packing begins.

FAQs

Does this tray use glue or tape?

No. The tray is held together entirely by mechanical pinch locks where the short walls slot into D-shaped cutouts in the base.

Can this tray be erected by machine?

Generally no. The unglued design and specific fold sequence are intended for manual assembly at the packing station.

Will my graphics show on the inside of the tray?

Only partially. The inside of the short walls will show the printed graphics because those panels roll over from the outside. The inside of the long walls and the base will show the unprinted side of the board.

Can I use a thick corrugated board for this tray?

This template is designed for folding carton board. Using thicker micro-flute corrugated is possible but means careful adjustment of the roll-over creases to prevent the board from cracking or resisting the fold.

Is this tray suitable for parcel shipping?

Not on its own. It is an open-top tray with friction locks. For parcel shipping, it should be placed inside a secure outer mailer or shipping box.

Why is board thickness so important for this design?

The pinch locks rely on exact friction to stay closed. If the board is thicker or thinner than the template expects, the locks may either fail to engage or tear the base panel.

How is the tray delivered?

The trays are delivered completely flat, making them highly efficient to store before use. They are erected on demand as items are packed.

Can a lid be added to this tray?

Yes, this tray is frequently paired with a separate full-telescope lid or a slip-on sleeve to fully enclose the product.
