When Bubble Wrap Isn’t Good Enough
Loose filler protects against impact, but it doesn’t hold products in position. It doesn’t create a reveal. It doesn’t communicate care. Mailer boxes with inserts do all three — combining secure transit protection with a presentation that tells your customer the product they ordered was handled with intention.
At The Mailer Boxes, we custom-design and manufacture inserts to fit your exact product profile. Whether you’re shipping a single delicate item or a multi-piece gift set, we’ll engineer an insert configuration that eliminates movement, prevents surface damage, and looks exceptional when the box is opened.
Insert Types and When to Use Them
Foam Inserts
Closed-cell PE or EVA foam, precision die-cut to match your product’s contours. Ideal for electronics, glassware, instruments, and any product where scratch prevention is critical. Foam inserts absorb shock and compress without transferring force to the product.
Corrugated Card Dividers
Lightweight, recyclable, and cost-effective for multi-unit packing. Corrugated dividers separate products within a single box — common for bottled goods, jars, and sets of items that could damage each other in transit. Matches the eco-credentials of our corrugated mailer boxes.
Paper Pulp / Moulded Fibre Trays
Formed from recycled paper pulp, moulded trays are a fully sustainable insert option with excellent structural rigidity. Popular in premium cosmetics, food, and health product packaging where sustainability messaging matters. Photographs beautifully and composts after use.
Rigid Card Trays
Grey board or laminated card, constructed into platform trays that hold products upright. Common in jewellery, watch, and premium accessory packaging — the product sits visibly above the tray edge, ready to be lifted out. Best paired with our luxury mailer boxes.
The Product Categories That Benefit Most
- Cosmetics and skincare — glass bottles and jars held securely, presented label-forward
- Food and confectionery — chocolates, macarons, and pastries presented as retail gifts
- Electronics and accessories — cables, earbuds, and devices held without rattling
- Jewellery and watches — elevated presentation matching product value
- Subscription boxes — curated multi-product layouts that photograph well
- Corporate gifting — consistent presentation across large send volumes
Frequently Asked Questions
How do I specify my insert dimensions?
Send us your product dimensions — height, width, depth — and any specific clearance requirements. We’ll model the insert configuration and share a proof for your approval.
Can I use inserts with my own boxes?
Yes. We produce inserts as a standalone product that can be fitted into existing box stock. Share your box’s internal dimensions and we’ll produce a compatible insert.
Are inserts recyclable?
Paper pulp and corrugated card inserts are fully recyclable. Foam inserts are not recyclable but are durable enough to be reused. If recyclability is a priority, we’ll recommend a fibre-based option.
Design the Inside as Carefully as the Outside
