EVF41220

Double-Wall Frame Tray

The EVF41220 is a premium folding carton tray that uses hollow, double-wall perimeters on all four sides to frame the product. Often called a buffer wall tray, it creates a substantial, high-value presentation while providing a physical standoff, or crumple zone, to protect fragile items from side impacts.

Because it relies entirely on mechanical tab-and-cut locks, this tray requires no adhesive during manufacturing and is delivered completely flat. The tradeoff for this clean, un-glued design is a larger material footprint and a multi-step manual assembly process at the packing station.

  • Order custom samples, short runs, or production runs.
  • US-based. Nationwide service.
  • Nationally competitive pricing & delivery costs.
  • Available in a wide variety of configurations.

Premium Retail and Fragile Goods Presentation

Premium retail display

The thick hollow walls create a picture-frame effect, making small or low-profile items look more substantial on the shelf.

Fragile electronics and cosmetics

The buffer gap between the outer edge and the inner wall provides a crumple zone, keeping delicate products away from direct side impacts.

High-end confectionery and gifting

The thick walls create a premium unboxing experience for chocolates or curated gift sets.

Boutique apparel and accessories

The clean, glue-free frame presents folded garments, wallets, or belts with a substantial border.

Retail and Packing Environments

Luxury and boutique brands

The clean, glue-free construction and thick walls signal high quality, especially when paired with premium solid bleached board (SBS) and high-end finishes.

Manual fulfillment operations

Because the tray requires folding multiple distinct panels and seating precise locking tabs, it fits best in environments where trained staff pack high-margin goods by hand.

Low-volume promotional runs

Because it requires no gluing, this tray is accessible for short runs where dedicated folder-gluer setup would be impractical.

When to Consider Simpler Trays

High-speed automated packing

This tray is designed for hand assembly. If the packing line relies on automated erection, a standard glued four-corner tray is worth comparing.

Strict budget constraints

The double-wall design on all four sides uses more material than a standard tray. If the hollow frame is not necessary for presentation, a standard roll-end tray is more material-efficient.

Board Choice and Assembly Planning

Board thickness and folding endurance

The locking cuts must be precisely matched to the exact board thickness. The material must also withstand multiple 90-degree folds without cracking along the highly visible top edges.

Outer shipping protection

This tray has no lid and relies on friction locks. It is not a standalone shipper and will require a tight-fitting sleeve or a master carton for distribution.

Print and finish layout

The outer walls, the top of the buffer frame, and the inner walls are all visible to the consumer, offering a large canvas for branding.

Assembly labor planning

The 24-panel fold sequence requires trained staff and dedicated time at the packing station.

Adjusting the Frame Width and Depth

Frame thickness

The width of the hollow buffer wall can be expanded or reduced to change the visual weight of the tray and adjust the internal volume for different product sizes.

Vertical cut offset

The locking cuts must be precisely tuned to the exact caliper of the chosen paperboard to ensure a tight friction fit without tearing.

Tray depth

The internal height can be adjusted to sit flush with the product or provide extra clearance for an insert.

Packing details

Die-cut blank sprawl

The double-wall structure on all four sides creates a large flat blank relative to the assembled volume. This reduces the number of blanks that can be nested on a single sheet.

Additional notes

Board thickness and lock security

The vertical cuts that hold the tray together are sized to the exact thickness of the paperboard. Changing board grades later in the process requires adjusting the template so the locks do not tear or slip.

FAQs

Can this tray be set up by automated machinery?

The multi-step process of rolling the buffer walls and inserting the locking tabs is designed for hand assembly at the packing station. It is rarely a fit for automated case erectors.

What type of paperboard fits this tray?

Folding boxboard (FBB) or solid bleached board (SBS) are usually preferred. The board needs excellent folding endurance to prevent cracking along the frame edges, and the thickness must be known in advance to size the locking cuts correctly.

Can I ship this tray through parcel networks as-is?

Parcel transit usually requires an outer mailer, sleeve, or master carton. The tray has an open top and mechanical locks that can dislodge under rough handling.

Does this tray require any glue?

The entire carton holds its shape using mechanical tabs that insert into vertical cuts on the inner walls, requiring no adhesive.

Can I change how thick the walls are?

The width of the hollow buffer walls can be adjusted to create a wider or narrower frame around your product, though this will change the overall flat size of the material needed.

Will the tray collapse if stacked?

The side flaps serve as internal pillars to support the hollow walls, but vertical strength depends heavily on your board choice and whether the tray is packed inside a supportive outer carton.

How does the tray stay together without adhesive?

The top and bottom buffer walls feature small tabs that fold downward and interlock with vertical cuts on the left and right inner walls.

Can I print on the inside of the tray?

Yes, the inner walls and the top of the buffer frame are visible to the consumer and can be printed along with the outer walls.
