Let’s start!

What is a Mailer Box?

A mailer box is a type of packaging made from 32-ect corrugated cardboard material and comes in two different thickness levels, such as E-flute 1/16” and B-flute 1/8″. These boxes are mainly used for directly shipping products without needing an additional shipping box.

They are lightweight compared to other shipping boxes and come with built-in interlocking flaps for secure, tape-free assembly. Ideal for e-commerce and personal use, mailer boxes provide a customizable surface for branding and create a memorable unboxing experience for items like clothing, electronics, and gifts.

Now that we know what mailer boxes are, let’s discuss standard sizes.
