No Insert = Damaged Product

Your product rattles around in the box. It shifts in transit. Customers open the box and it’s scratched or broken. A good insert holds the product secure and absorbs shock — that’s what inserts are for.

How Inserts Protect Your Product

Protection	How It Works
Holds product in place	No movement = no scratches
Absorbs shock	Foam compresses on impact
Prevents contact	Product doesn’t touch box walls
Cushions corners	Fragile edges protected
Distributes weight	No point pressure on product

Protection Level by Insert Type

Insert Type	Protection	Best For
EVA foam	Excellent	Fragile electronics, glass
Velvet-covered board	Good (looks premium)	Cosmetics, jewelry
Cardboard divider	Fair	Durable products
Molded pulp	Good	Shipping, eco-friendly
Styrofoam	Good	Not eco-friendly

Insert Thickness Guide

Tipo de producto	Minimum Thickness
Fragile glass	20–30mm
Electronics	15–20mm
Cosmetics	10–15mm
Jewelry	5–10mm
Durable items	5mm

Rule: Thicker insert = more protection, but also more cost and less space.

Shipping Damage Benchmarks

Packaging Level	Typical Damage Rate
No insert, just box	5–15%
Cardboard divider only	3–8%
Molded pulp insert	1–3%
EVA foam custom insert	Under 1%

Common Protection Mistakes

No insert — Product rattles around, gets scratched

Loose fit — Product moves in cavity

Too thin insert — Doesn’t absorb shock

Wrong material — Hard plastic insert scratches product

No corner protection — Fragile corners break

Product touches box walls — Rubs and scratches

No top insert — Product moves up and down

How to Test Insert Protection

Shake test — Shake the box. Nothing should move.

Drop test — Drop from 30cm. Product should be fine.

Corner test — Press on corners. No give.

Product fit — Product should be snug but removable.

Protecting Different Products

Producto	Insert Recommendation
