Custom Inserts & the Unboxing Experience: A Practical Guide
An insert is the fitted piece inside a box that holds your product in place – and it does two jobs: it protects the contents in transit, and it presents them like a gift when the box is opened. For e-commerce and subscription brands especially, the insert is what turns a plain box into an unboxing worth sharing. This guide covers the main insert types and how to design the moment. Every order includes a free dieline, so your insert is built to your product on our custom boxes.
Key takeaways
- Inserts protect and present: they stop movement in transit and frame the product on opening.
- Match the insert to the product: paperboard for light items, foam for fragile ones.
- Eco options exist: paperboard and molded pulp replace foam for a greener unboxing.

What does a packaging insert do?
An insert fills the empty space inside a box so the product cannot slide, rattle, or knock around. That protects fragile items, but it also does something subtler: a snug, intentional fit signals care and quality the moment a customer opens the box. The best inserts do both at once.
Types of custom inserts
The right insert depends on the product’s weight, fragility, and the look you want. The table below maps the main types to their best use.
| Insert type | Best for |
|---|---|
| Paperboard inserts | Light products and a clean, printable, recyclable fit. |
| Corrugated inserts | Heavier items needing more strength and cushioning. |
| Foam inserts | Fragile or precision items (electronics, glass) needing a tight hold. |
| Molded pulp | An eco-friendly, recyclable alternative to foam. |
| Dividers & partitions | Multi-unit sets – bottles, jars, or a product line in one box. |
Inserts by use case
- Fragile products – foam or molded pulp cradles glass, electronics, and delicate items.
- Multi-packs & sets – dividers keep bottles and jars apart and organized.
- Subscription & gift boxes – paperboard platforms arrange items for a styled reveal; see subscription boxes.
- Premium products – fitted inserts in a rigid box create a true luxury presentation.
How to design a great unboxing
The unboxing is free marketing when it is done well – customers photograph and share it. A few principles:
- Make the reveal intentional. A fitted insert presents the product face-up, not buried in filler.
- Print the interior. A branded inner surface or a message under the lid extends the brand inside the box.
- Add a small extra. A thank-you card or sample insert turns a delivery into a relationship.
- Keep it tidy. Right-size the box so the insert fills it cleanly – no rattle, no waste.
Inserts pair naturally with a branded mailer box, which is the workhorse of e-commerce unboxing – see our retail & e-commerce guide for the full picture.
Are eco-friendly inserts available?
Yes. Paperboard, corrugated, and molded-pulp inserts are recyclable and increasingly replace plastic foam, so you can protect the product without undermining a sustainable brand story. See our sustainable packaging guide and eco-friendly boxes.

Do you make custom inserts to fit my product?
Yes. We build inserts to your product’s exact dimensions with a free dieline, so the fit is snug and protective – no off-the-shelf compromise.
Which insert is best for fragile items?
Foam or molded pulp gives the tightest, most cushioned hold for glass, electronics, and delicate products. Corrugated inserts also work well for moderate protection.
Can inserts be eco-friendly?
Yes. Paperboard, corrugated, and molded-pulp inserts are recyclable alternatives to plastic foam, ideal for sustainability-focused brands.
Is there a minimum order for boxes with inserts?
Our minimum is just 100 boxes, with no die or plate fees, and inserts are quoted along with the box.
