What Is a Roll End Tuck Front (RETF) Mailer Box? Everything You Need to Know

Have you ever noticed that some mailer boxes stay together without any glue or tape? This clever design is behind one of the most popular boxes used for shipping and packaging.

A Roll End Tuck Front (RETF) mailer box is a type of corrugated box that folds and locks itself together in a solid form factor. Its rolled side panels make the box stronger, and the front flap tucks in to keep the lid closed, so you do not need glue or tape to put it together. This design is widely used in e-commerce, subscription, and retail packaging because it is strong, easy to assemble, and looks good when opened.

Why Is It Called a Roll End Tuck Front Box?

RETF mailer boxes stand out for their clever design. They use smart geometry and sturdy construction to shape the box and make it strong. The name also hints at how these boxes are put together.

  • Roll end means the side panels fold inward. This makes the walls stronger and forms corner pockets that hold the two front flaps in place.
  • Tuck front describes the box lid, which has a long front flap and two wings. When you close the box, the flap folds over and the wings fit into the side pockets, keeping the lid shut securely.
