Use foam inserts to stop movement in transit, stage every item in a kit, and keep unboxing repeatable for photography, PR, and retail.
Since 2018, Seven Packaging has produced magnetic boxes with precision foam inserts for U.S. brands across beauty, CBD, electronics, apparel, and gifting. We help you match foam density, thickness, color, and cavity layout with your product weights, shipping route, and visual goals so the inside feels as considered as the outside.
Why Add Foam Inserts to Magnetic Boxes?
- Lock-in protection: Custom cavities hold each item in place so products don’t rattle or collide in transit.
- Photo-ready layout: Every bottle, compact, or device sits in the same position — perfect for PR kits and repeatable unboxing shots.
- Flexible materials: Choose EVA, XPE, PU foam, or layered foam to balance softness, support, and budget.
- Brand-matched interior: Foam can be black, white, or color-tinted, and can be velvet-wrapped for a softer feel.
- Works across styles: Compatible with book-style magnets, magnetic drawers, and collapsible magnetic boxes.
Built by Seven Packaging — rigid magnetic box experts who think through the insert as carefully as the wrap. We’ll help you design foam layouts and depths that protect your product and make unboxing feel intentional, not accidental.

Compare Foam Inserts vs. Velvet Platforms vs. Card / Molded Pulp
| Feature | Foam Inserts | Velvet Platforms | Card / Molded Pulp Inserts |
|---|---|---|---|
| Product hold & protection | Strong hold; absorbs shocks; great for fragile or mixed items | Moderate hold; best for lighter products with shallow recesses | Good structural support; better for simple shapes and sets |
| Best for | Beauty kits, glass bottles, electronics, PR / launch kits | Jewelry, watches, small accessories, collector pieces | Soaps, apparel, stationery, simple bottles or jars |
| Look & feel | Clean cut cavities; can be velvet-wrapped for a softer look | Luxurious fabric surface; works well with magnetic gifting | Paper-based; can be printed or color-matched to the box |
| Shape complexity | Handles complex, irregular shapes and multiple depths | Best for circles, ovals, and simple recess shapes | Best for simpler cavities; complex forms need more tooling |
| Weight & shipping | Medium weight; adds density but protects well | Light–medium; depends on board and padding under velvet | Typically lightest; paper-first construction |
| Sustainability profile | Engineered foams; some options more recyclable than others | Mixed materials (board + foam + fabric); more design-dependent | Paper or pulp based; often more recycling-friendly |
| Cost range | Medium; depends on foam type, thickness, and cavity count | Medium–higher; fabric + labor for wrapping | Low–medium; efficient for larger runs and simple layouts |
Gallery — Foam Inserts in Magnetic Boxes
See how custom foam inserts transform magnetic closure rigid boxes into made-to-measure homes for your products — with precision-cut cavities, layered interiors, and velvet-wrapped platforms that hold everything in place from shelf to doorstep. Foam layouts can be planned alongside ship-testing guidance such as ISTA 3A and relevant ASTM packaging standards.
Foam Insert Styles & Interior Add-Ons

FAQs — Foam Inserts for Magnetic Boxes
What types of foam do you use for inserts?
We commonly work with EVA, XPE / cross-linked, PU, and PE foams. Each material has different density and feel — from firm, high-protection foams for glass and electronics to softer foams for lighter beauty and accessory items. Tell us your product and we’ll recommend the best match.
Can you cut foam to complex shapes?
Yes. We routinely cut custom cavities, finger notches, and logo-shaped pockets, and can build multi-level layouts where one layer lifts out to reveal another. For best results, we work from product samples, CAD files, or accurate dimensional drawings.
Can foam inserts be velvet-wrapped or branded?
Absolutely. Foam can be velvet- or fabric-wrapped for a luxury feel, or paired with a printed card cover that sits over the cavities. We can also explore subtle logo debossing or printed overlays depending on your design and budget.
How do foam inserts affect sustainability?
Foam adds protection and extends product life, but it is a separate material stream from paper. We can look at lower-density foams, minimal cutouts, or hybrid foam + paper solutions where sustainability is a priority, and we’ll flag options that are easier to separate or recycle at end-of-life.
What’s the minimum order quantity for foam inserts?
Most foam-inserted magnetic box projects start around 200–500 units, depending on foam type, cavity complexity, and box style. Once your layout and artwork are approved, standard production timing is typically 10–14 business days plus shipping.
