About this product

This unglued paperboard insert acts as an elevated platform inside a master carton. By folding down two side legs, it creates a bridge that centers and cradles your product, keeping it away from the outer walls.

Because it relies on the outer carton to hold its shape, it requires no adhesive. It is an efficient way to improve unboxing presentation or provide internal void fill for lightweight to medium-weight items.

Common uses

Cosmetics presentation
Electronics centering
Void fill for fragile items

Product presentation and internal void fill

Framing cosmetics and electronics for retail unboxing

Elevates cosmetics, electronics, or luxury goods toward the top of the outer carton, framing the item cleanly as soon as the box is opened.

Creating a hidden lower compartment for cables and manuals

The elevated platform leaves a deliberate void beneath the product, providing a clean way to store power cords, instruction booklets, or secondary accessories out of sight.

Preventing lateral shift for fragile components

Keeps a single component suspended in the center of a larger box, preventing it from shifting against the outer walls during transit.

Isolating heavy primary products from lightweight accessories

Acts as a physical barrier between a heavier main item and smaller, fragile components packed below it, preventing crushing during handling.

Packing lines and presentation programs

Manual kitting and fulfillment lines

Because it ships flat and requires only two simple 90-degree folds, it is fast to assemble on hand-packing lines. Operators fold the legs, push the insert into the carton, and drop the product into the center.

Luxury presentation and unboxing programs

The broad top platform provides a clean, uninterrupted surface that frames the product, making it useful for high-end retail goods where the unboxing experience matters.

Subscription boxes with variable product sizes

Allows a single standardized outer carton to be used for different monthly items by simply swapping the internal platform insert to match the new product's dimensions.

When to compare other internal supports

When packing heavy industrial products

If the product is heavy enough to cause the two unglued legs to buckle or the central platform to sag, a four-sided pedestal or a corrugated partition may be necessary.

When the insert must act as a standalone package

This insert has no outer closure and will immediately splay flat if not constrained by an outer box. It cannot be used on its own.

Fit, clearance, and board stiffness

Matching the insert footprint to the master carton

The insert's width and length must be sized slightly smaller than the exact internal dimensions of the outer carton. A tight friction fit is what keeps the legs locked at 90 degrees.

Selecting board stiffness for the platform span

The wider the platform and the heavier the product, the stiffer the board needs to be. Standard folding carton board works well for light items, while heavier goods may require a micro-flute corrugated board to prevent bowing.

Choosing between cradling flaps and a clean cutout

The standard design uses inner flaps that fold down to grip the product, while the variant uses a clean die-cut hole for a rigid, exact-dimension fit.

Setting the elevation height for lower clearance

The height of the side legs determines how high the product sits inside the box, which dictates how much clearance remains below the platform for other items.

Adjusting the cutout and platform height

Adjusting the side leg height for vertical clearance

The legs can be lengthened or shortened to change the product's presentation height or to increase the storage volume in the lower compartment.

Contouring the central aperture to the product shape

The central hole must be sized precisely to grip the product without tearing at the corners during insertion. It can be die-cut to match the specific profile of the item.

Adding finger cutouts for easier insert removal

If the end user needs to lift the platform to access items stored beneath it, small half-moon cutouts can be added to the edges of the platform.

Board and packing details

Print and surface finish on the top platform

The top platform provides a large, uninterrupted surface for branding, instructions, or color-matching the outer carton. The legs are typically hidden once inserted.

Cutout edge variants

F80.02.00.00 (Cradling Flaps)

The standard design features four inner flaps that fold downward at an angle when the product is inserted, creating a sloped collar that grips the item.

F80.02.00.00.a (Clean Cutout)

A variant with a simple, clean rectangular hole and no inner flaps. This provides a rigid, exact-dimension aperture and simplifies manufacturing.

Additional notes

Outer carton fit and leg splay

The insert must be sized to the exact inner dimensions of the master carton. If the carton is too loose, the legs will splay and the platform will drop.

Aperture corners and insertion tear risk

Forcing an oversized product into the cutout can tear the corners of the aperture. Proper sizing and optional relief cuts can prevent this.

FAQs

Assembly and packing

Does this insert require glue or tape?

No. It relies entirely on a friction fit. The walls of your outer carton prevent the folded legs from splaying outward.

How is the insert delivered to the packing line?

It is delivered completely flat. Packers make two simple 90-degree folds before pushing it into the outer carton.

Can it be inserted by automated cartoning equipment?

This style is typically folded and inserted by hand. Automated insertion is possible but requires specialized pick-and-place robotics.

Product fit

How does the product stay secure in the cutout?

In the standard design, four inner flaps fold downward to grip the product. The cutout dimensions must be matched closely to your product's profile to ensure a snug fit.

What happens if the outer carton is slightly too large?

The insert relies on the outer carton walls to hold its shape. If the carton is too loose, the legs will splay outward and the platform will drop.

Board and materials

Can this platform be made from corrugated board?

Yes. While often made from paperboard for lightweight items, micro-flute corrugated can be used if the platform needs to support a heavier product without sagging.

Modifications

Can the central cutout be shaped to match my product?

Yes. While a rectangle is standard, the aperture can be die-cut to match the specific contour of your item, reducing the risk of tearing at the corners.

Print and branding

Can the top surface of the platform be printed?

Yes. The top platform provides a large, uninterrupted surface for branding, instructions, or color-matching the outer carton. The legs are typically hidden once inserted.
