Custom Box Inserts That Hold Everything in Place
The Part Customers Feel First
An insert is the internal structure that positions and protects the product inside a box. Get it right and the contents sit perfectly, arrive undamaged, and reveal themselves in a deliberate order. Get it wrong and even a beautiful box feels loose and cheap when it's opened.
We engineer inserts to your specific product, not to a generic cavity. Depending on the item's weight, fragility, and the presentation you want, that might mean a die-cut paper platform, a corrugated divider grid, or a molded-look foam cradle. Inserts pair with any of our box styles, from mailers to rigid presentation boxes.

Designing for Protection and Presentation
Inserts balance two jobs: keeping the product from moving and staging how it appears when opened. For fragile or high-value items, foam cradles absorb shock and hold a snug fit. For retail and gifting, printed paperboard platforms lift the product into view. We prototype the fit so tolerances account for real material thickness before production.
Prototyping the Fit
An insert only works if the fit is right, so we prototype tolerances against real material thickness before production. A cavity that's a hair too tight makes pack-out slow; too loose and the product rattles. For fragile or high-value items, foam cradles absorb shock and hold a snug fit; for retail and gifting, printed paperboard platforms lift the product into view; for shipping, corrugated dividers add economical protection. Inserts pair with any of our box styles, from corrugated mailers to rigid presentation boxes, and can be printed to match your brand where the material allows.
Matching the Insert to the Product
An insert does two jobs at once: it immobilizes the product so it survives handling, and it stages the product so it presents well the moment the box is opened. Getting both right starts with the shape and fragility of what goes inside. A rigid, robust item may only need a simple corrugated pad or a scored partition to stop it sliding, while a delicate or oddly shaped item benefits from a fitted cavity that cradles it precisely and keeps it from touching neighboring pieces or the box walls.
Material choice follows the level of protection and the look you want. Corrugated and folded paperboard inserts are economical, recyclable, and quick to produce, making them a natural fit for shipping and multipacks. Molded pulp gives contoured cradles from recycled fiber for a natural aesthetic. Foam and flocked platforms suit heavier or premium goods where a soft, snug seat and a refined surface matter. Whatever the material, we build the insert to your exact product dimensions and to the internal size of the box it drops into, so nothing rattles and the assembly still packs out efficiently.
