Types of Corrugated Boxes

Monday, October 12, 2020

There are many different types of corrugated boxes. Before discussing the types available, let’s first discuss what they are all composed of. 

There are two main components: liner and medium. Both are made up of containerboard. The liner is a flat material that typically is on the outer surface of the board but also on the inside for structure. The medium is the paper that is formed into flutes (learn more about flutes here) and glued between the linerboard.

The most commonly created linerboard and medium varieties are:

Single Face (A): one medium is glued to one liner board

Single Wall: (B): one medium is glued between two sheets of linerboard

Double Wall (c): three sheets of linerboard with two mediums in between

Triple Wall (D): four sheets of linerboard with three mediums in between.


Types of Box Styles:

  • Regular Slotted Container (RSC): all the flaps are the same width and the flaps (usually lengthwise flaps) are ½ the container’s width. This allows them to meet in the center.


  • Half Slotted Container (HSC): same as the RSC but without one set of flaps.


  • Full Telescope Design (FTD): a two-piece box made from scored and slotted blanks or trays.


  • One Piece Folder (OPF): one piece of board is cut so it provides a flat bottom, with flaps that form the side and ends.


  • Rigid Box (Bliss Box): three pieces of rigid box which includes two identical end panels and a body that folds.


Besides the types of corrugated boxes listed above, there is also a variety of inner packing pieces. These interior forms are typically used to cushion or separate products as well as strengthen the box or fill voids.
