About this product

This one-piece corrugated insert folds into a raised platform, creating a false bottom or elevated presentation stage inside a master carton. It features a solid top panel with a thumb cut for easy removal, allowing packers or customers to access the space underneath.

Because it has no native locks or glue seams, the insert relies entirely on the walls of the outer box to hold its shape. It is delivered flat, folds together in seconds, and drops directly into the shipper.

Common uses

Presentation elevation for unboxing experiences.
Void fill replacement for standardized master shippers.
Layer separation with a specific height requirement.
Hiding accessories or manuals underneath a primary product.

Common Uses for False Bottom Inserts

Presentation Elevation

Lifts the primary product to the top of the box for a better unboxing experience, preventing smaller items from getting lost at the bottom of a deep carton.

Hidden Accessory Storage

Creates a clean void space underneath the platform to store cables, manuals, or secondary components out of sight.

Heavy Void Fill Replacement

Replaces loose fill or crumpled paper when a specific, predictable height needs to be filled inside a standardized master shipper.

Multi-Tiered Packing

Creates a clean, flat floor above a lower layer of goods, allowing a second tier of products to be packed without resting directly on the items below.

Product Categories Using False Bottoms

E-commerce and Subscription Kits

Provides a clean, structured unboxing presentation without requiring complex custom thermoformed trays or glued internal structures.

Electronics and Hardware

Allows heavy primary devices to sit securely on top while keeping power supplies and mounting hardware separated underneath.

Cosmetics and Glassware

Elevates small jars or bottles to the top of a standard shipper, improving presentation while maintaining a protective crush zone at the base.

When to Compare Other Internal Packaging

Standalone Use

This insert has no locking tabs and will unfold if not constrained. If you need a standalone tray or inner box that holds its own shape outside of a master carton, compare standard locking trays.

Multi-Item Separation

If you need to separate multiple items on the same layer, a slotted partition or a die-cut insert with specific product cavities will perform better than a flat platform.

Fit, Board, and Packing Decisions

Master Carton Fit

The insert must be sized to the exact internal dimensions of your outer box. A fit that is too loose will allow the platform to shift, while a fit that is too tight will cause the support walls to bow.

Board Thickness and Flute

The weight of the product resting on the platform dictates the board choice. Standard E-flute works well for lighter items, while B-flute or C-flute may be necessary to prevent the top panel from sagging under heavier loads.

Platform Height

The height of the false bottom determines the volume of the void space below. This dimension should be checked against the height of any accessories being stored underneath.

Thumb Cut Orientation

The thumb cut can be placed on any edge of the top platform. Its position should be chosen based on how the packer or customer will naturally reach into the box to lift the insert.

Adjusting the Platform and Access

Thumb Cut Sizing

The semi-circular thumb cut on the edge of the platform can be widened or deepened to accommodate different handling needs, ensuring easy removal even with gloves.

Platform Height Adjustment

The template automatically recalculates the height of the inner support walls to account for board thickness, ensuring the top platform always sits perfectly flush.

Corner Chamfers

The angled cuts on the support walls can be adjusted to provide more or less clearance, preventing the corrugated board from binding against itself during assembly.

Packing details

Assembly and Packing Labor

This insert is designed for hand assembly. The packer folds the four walls upright, folds the top platform over, and drops it directly into the waiting master carton without needing tape or glue.

Additional notes

Board thickness and flush surfaces

When specifying the height of the false bottom, the underlying support walls are cut slightly shorter to account for the thickness of the corrugated board, ensuring the top platform sits perfectly level.

FAQs

Does this insert require glue or tape to hold its shape?

No. The insert is folded into shape and relies entirely on the four walls of your outer shipping box to keep it from unfolding.

How do I ensure the insert fits my box?

The insert's length and width should closely match the internal dimensions of your master carton. A snug fit prevents the platform from shifting during transit.

Can this platform support heavy items?

It can support moderate weight, as the top platform rests directly on three corrugated support walls. For very heavy items, upgrading to a thicker board flute will help prevent the top panel from bowing.

Can the thumb cut be moved or removed?

Yes. The thumb cut is included by default to make it easy to lift the platform out of the box, but it can be resized or removed if your packing process does not require it.

Why are the corners of the support walls angled?

The chamfered corners provide clearance during assembly. They prevent the corrugated board from binding against itself when the walls are folded upright.

How is this insert delivered?

It is delivered flat and is folded into its 3D shape by the packer right before being placed into the master carton.

Can I use this insert as a standalone tray?

No. This insert has no locking tabs or glued seams. It will unfold if it is not constrained by the walls of an outer box.

What happens to the insert if I choose a thicker corrugated board?

The template automatically adjusts the height of the underlying support walls based on the board thickness, ensuring the top platform remains level and flush.
