In today’s fast-paced eCommerce world, product packaging does more than just deliver goods — it tells a story, builds brand identity, and creates a memorable customer experience. One packaging option that has gained popularity across industries is the mailer box with inserts. Combining form and function, these boxes protect products while elevating the unboxing experience.

This comprehensive guide explores everything you need to know about mailer boxes with inserts — from their construction and customization options to their benefits and common uses.

What Are Mailer Boxes with Inserts?

Mailer boxes are sturdy, self-locking cardboard boxes typically made of corrugated or rigid paperboard, designed for shipping or gifting. When paired with custom inserts, they become even more effective and appealing.

Inserts are interior components made from cardboard, foam, molded pulp, or other materials, designed to hold products securely in place. Inserts can be custom cut to fit the exact dimensions and shapes of products, preventing movement during transit and presenting them in an aesthetically pleasing layout.

2. Foam Inserts

• Offer high protection for delicate or electronic items

• Available in custom-cut shapes and colors

• Often used in luxury packaging or tech gadgets

3. Plastic or Molded Pulp Inserts
