Why the Insert Matters
The insert is what holds your product in place and makes the unboxing feel premium. A poorly fitting insert rattles, scratches, and looks cheap. A precision-cut insert makes the customer feel like they’re opening something valuable.
At Chengtop, we design inserts around your exact product — you send us the dimensions and arrangement, we cut it to fit.

Manufacturing Methods
Laser-Cut EVA Foam
A laser cuts the exact product shape out of foam. Precision, custom shapes, no die cost. Best for short runs and custom products.
Die-Cut Cardboard
A steel die cuts the insert from cardboard sheets. Fast for high volume, but requires a die (one-time cost).
Molded Pulp
Recycled paper pulp is molded into shape using a heated die. Eco-friendly, but less precise than foam.
Flocado de terciopelo
Velvet is applied over an EVA foam or cardboard base. Soft, plush, and premium.
Single-Layer vs. Two-Layer Inserts
Single-Layer
One piece of foam or velvet with product cutouts. Simple, cost-effective, most common.
Two-Layer
A top velvet layer (for looks) over a bottom EVA foam base (for structure). Used when you want the velvet feel but need foam thickness.

The insert should hold the product snugly — it shouldn’t rattle when shaken.
Common Mistakes to Avoid
- Measuring the box, not the product — Measure each item, then we design the insert
- Too tight fit — Products should slide in and out easily, not jam
- Forgetting clearance — Add 1–2mm for easy insertion
- Wrong foam color — Black shows dust; dark colors hide it better
- Not testing — Always test the sample with your actual product
