Inserts are easy to overlook, but they decide how the product sits inside the box. They also affect material choice, cost, assembly time and sustainability requirements.
Paper inserts are often useful when a brand wants a paper-based packaging system. Plastic trays can give precise shape control, but they may not fit every brand policy. The right choice depends on product weight, protection needs and buyer requirements.
Insert comparison
| Insert type | Good for | Watch out for |
|---|---|---|
| Paperboard insert | Cosmetics, candles, gift sets, light products | May need testing for heavier items |
| Corrugated insert | Shipping kits, e-commerce packs | Thicker and more utilitarian |
| Molded pulp-style insert | Natural look, protective packing discussions | Shape and finish need early confirmation |
| Plastic tray | Precise product holding | May conflict with plastic reduction goals |
| Foam insert | Fragile or premium products | Check buyer policy before quoting |
When paper inserts make sense
Paper inserts work well when the product is not too heavy and the brand wants to reduce plastic. They can be printed, die-cut and matched to folding cartons, mailer boxes or gift boxes.
They are common in custom cosmetic boxes, candle gift sets and promotional kits.
When stronger inserts may be needed
For glass, electronics, heavy jars or fragile premium products, protection may matter more than using one material family. In that case, send the product weight and shipping route so the supplier can suggest a practical insert.
Plan inserts before artwork
The insert affects internal dimensions. If you approve the outside box artwork first and change the insert later, the box size may need to change.
