Ask a buyer what they look at first on a custom box quote and most will say the board or the print. In practice, the part that decides whether a product arrives intact — and whether the unboxing feels considered — is the insert. It is also the most frequently under-specified line on a specification sheet. Get it wrong and the outer box, however well printed, will not save the shipment.
What the insert actually does
An insert has three jobs, and they are not equally obvious. It holds the product in a fixed position so it does not rattle. It absorbs shock in transit. And it presents the product when the lid comes off — which is the moment a customer forms an opinion and, increasingly, the moment they take a photograph. A box can look expensive and still fail all three.
This is why we ask about the product before recommending a material. A 30 gram lipstick and a 900 gram glass bottle need completely different solutions, and the cost difference between getting it right and getting it comfortable is usually small compared with the cost of a damaged shipment.
The four common insert materials
EVA is a cut foam with a dense, velvet-like surface. It holds tight tolerances, looks finished without a covering, and is the usual choice for cosmetics, watches and electronics where presentation matters. It is the most expensive of the four and the least friendly to recycling programmes.
Foam — usually PE or EPE — is lighter and cheaper, with excellent cushioning but a softer, more industrial surface. It is normally covered with fabric or paper when it will be seen. It suits protective shipping more than premium gifting.
Paperboard inserts are folded from card, sometimes with a die-cut window or platform. They are low cost, printable, recyclable in the same stream as the box, and adequate for light products. They absorb less shock than foam.
Moulded pulp is pressed from recycled fibre. It cushions well, stacks efficiently, and reads clearly as an environmental choice — which matters increasingly for EU buyers under PPWR. It is less precise than EVA and the tooling cost is higher at low volumes.
| Insert | Precision | Shock absorb | Cost | Recyclability |
|---|---|---|---|---|
| EVA (cut foam) | Very tight, holds shape | Good | Highest | Poor, usually mixed material |
| Foam (PE / EPE) | Loose, compresses | Very good | Low to mid | Depends on local stream |
| Paperboard | Moderate | Light duty only | Lowest | Good, same stream as box |
| Moulded pulp | Moderate | Good | Mid, tooling upfront | Best, widely accepted |
Three specification mistakes we see repeatedly
The first is an insert cut too tight. It looks perfect on the bench and then the customer cannot lift the product out without tipping the box — one of the most photographed complaints in unboxing videos. Leave a finger gap; it costs nothing.
The second is choosing the insert for its looks and ignoring the shipping environment. A beautiful EVA platform offers almost no protection if the carton is dropped. If the parcel travels alone through a courier network, cushioning matters more than presentation.
The third is picking a material the destination market will not accept. Some European retailers now ask for fibre-based inserts, and mixed-material EVA can complicate that. If your buyer has a packaging policy, send it to us before we specify — it is far cheaper to design around it than to retool.
Matching insert to product
| Product | Recommended | Reason |
|---|---|---|
| Lipstick, serum, small cosmetics | EVA or paperboard | Light weight, presentation driven, tight tolerance |
| Glass bottle, perfume | EVA with deeper cavity | Heavier, fragile, needs positional hold |
| Watch, jewellery | EVA, fabric covered | Premium surface, item must sit flat and centred |
| Electronics, accessories | Moulded pulp or foam | Shock protection and stacking matter most |
| Multi-item gift set | EVA with separate cavities | Keeps each item in place, one visual layout |
| Eco-positioned skincare | Moulded pulp | Fibre based, aligns with EU buyer expectations |
What to send us before quoting
Four things: the physical product or its exact dimensions and weight; whether it is fragile; how it will be shipped (a single parcel, palletised freight, or retail shelf); and any material requirement from your buyer or target market. With those, we can usually recommend an insert the same day and tell you honestly whether the cheap option will be good enough.
If you already have a box and only need the insert, say so — inserts can be tooled and produced independently, and reusing an existing outer box is one of the fastest ways to cut cost on a repeat order.
