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).

Polpa moldada

Recycled paper pulp is molded into shape using a heated die. Eco-friendly, but less precise than foam.

Flock de veludo

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.

	Single-Layer	Two-Layer
Custo	Mais baixo	Mais alto
Sentir	Bom	Premium
Espessura	Single foam	Velvet + foam
Ideal para	A maioria dos produtos	Luxury gifts, high-end
