A box insert is the piece that sits inside your box and keeps the product from moving around. It does two jobs at once. It stops things sliding into each other in transit, which is where most damage comes from, and it makes the box look deliberate when a customer opens it instead of a product rattling around in packing peanuts. The right insert depends on how fragile and heavy your product is, how many pieces go in one box, the look you want, and your budget.
What an insert is for
Protection comes first. A snug insert holds the product still and keeps fragile items off the box walls, so they survive being thrown around by a courier. Presentation comes second, and it matters more than people expect. A fitted tray or platform frames the product the moment the box opens, which is a big part of why a good unboxing feels premium. A well-made insert usually pays for itself in fewer damaged returns and a stronger first impression.
The main types of insert
There are four you will actually run into. Cardboard and paperboard fitments are die-cut to your product’s shape, so trays, platforms, and sleeves. They are cheap, recyclable, and the usual choice for lighter products and clean retail presentation. Corrugated partitions and dividers slot into the box to keep multiple units apart, which is what you want for bottles, jars, or a multipack, and they take more weight than paperboard. Foam inserts, either die-cut or the egg-crate kind, cradle fragile, heavy, or expensive items, so if you ship glass, electronics, or high-end cosmetics, foam absorbs shock better than anything else. Molded pulp is the moulded, recyclable option for uniform shapes, and it is worth a look if sustainability is a priority for your brand.
How to pick the right one
Start with the product, not the insert. If it is fragile or expensive, go with foam. If it is light and you want it to look good on a shelf, a die-cut cardboard tray wins on price and recyclability. Shipping several units in one box? Corrugated dividers stop them knocking together. If your brand leans eco, cardboard and molded pulp beat foam. And keep the budget honest by matching the protection to what the product actually needs instead of over-building it.
Sizing the insert with your box
The insert is built around your product’s exact measurements, so getting those right matters. Our guide on how to measure a box walks through it, and you will want to measure the product at its widest points. Remember that the insert takes up room, so the inside depth of the box has to fit the product and the insert together. Inserts show up most in rigid boxes, where a foam bed or fitted platform is part of the premium feel, but they work just as well in mailers and product boxes.
Custom inserts with no minimum
We cut custom inserts to fit your product and box, whether that is cardboard, corrugated, or foam, and there is no minimum order, so you can add one to a small first run instead of committing to thousands. For combined box and insert pricing, see how much custom boxes cost, then request a quote with your product dimensions and we will spec the insert alongside the box.

What is a box insert?
A box insert is a fitted piece that sits inside your box and holds the product in place. It protects the product from moving and getting damaged in transit, and it presents the product neatly when the box is opened. The common ones are die-cut cardboard fitments, corrugated dividers, and foam.
What are the different types of packaging inserts?
The main types are cardboard inserts (die-cut trays and dividers that are cheap and recyclable), corrugated partitions for heavier or multi-unit shipping, foam inserts for fragile or high-value items, and molded pulp as an eco option for uniform shapes. Which one you use comes down to weight, fragility, look, and budget.
Which insert is best for fragile products?
For fragile, heavy, or high-value items like glass, electronics, and ceramics, a die-cut foam insert gives the most protection because it cradles the product and absorbs shock. For lighter fragile items, a snug die-cut cardboard fitment often does the job while staying recyclable and cheaper.
Cardboard or foam inserts, which should I use?
Cardboard inserts are lighter, cheaper, fully recyclable, and great for retail presentation and light to moderate protection. Foam costs more and is less eco-friendly but protects fragile and heavy items far better. Plenty of brands use cardboard for presentation and add foam only where the product really needs cushioning.
Do box inserts add a lot to the cost?
Inserts add a per-unit cost on top of the box, and how much depends on the type. Die-cut cardboard is the most affordable and foam costs more. For most products the better presentation and fewer damaged returns are worth it. Ask for the box and insert together on your quote so you see the real combined price.
Can I get custom inserts with no minimum order?
Yes. We make custom inserts to fit your product and box with no minimum order, so you can add them to a small first run instead of buying thousands. Send your product dimensions with your quote and we will spec the insert.
