Please see below for information associated with the most common box styles

Regular Slotted Container - RSC

RSC - The most common box style.  All flaps have the same length and the two outer flaps (normally the lengthwise flaps) are one-half the container's width so that they meet at the center of the box when folded.  If the product requires a flat, even bottom surface or the protection of two full layers, a fill-in pad can be placed between the two inner flaps.


This is a hightly efficient design for many applications.  

One Piece Telescoping Container - OPT

OPT - This box is usually set up on automatic equipment.  It is frequently used for the shipment of processed and frozen meats.


Formed from a single rectangular piece of scored and slotted board, the style combines the features of telescope styles and folders.  At least two layers of board on one side and both ends provide stacking strength and the bottom and top are unbroken. 

Partial Overlap Container - POL

POL - This style is used when the length of the box is considerably greater than the width, resulting in a long gap between the inner flaps.  The sealed overlap helps to keep the outer flaps from pulling apart.  


All flaps have the same length.  The outer flaps overlap by 1" or more.  The box is easily closed, usually with staples driven through the overlap area.  

One Piece Folder - OPF

OPF - One piece of board is cut so that it provides a flat bottom, with flaps forming the sides and ends, and extensions of the side flaps meeting to form the top.  

Full Overlap Slotted Container - FOL

FOL - This style is especially resistant to rough handling.  Stacked on its bottom panel, the overlapping flaps provide added cushioning.  Stacked on it's side, the extra thickness provides added stacking strength.


All flaps have the same length (the width of the box).  When closed, the outer flaps come within 1" of the complete overlap.

Design Style Tray Full Telescoping Container - DST/FTC
Half Slotted/Full Telescoping Container - HSC/FTC

DST/FTC - Design Style Tray Full Telescoping container.


HSC/FTC - The two piece body is made from two half-sloted containers.  

Half Slotted/Partial Telescoping Container - HSC/PTC

HSC/PTC - This style is suitable for products that may settle or that may be safely compressed.  The box is sometimes overfilled and the style's flexibility allows it to remain intact as the settling or compression take place.


A partial telescope must be less than, but at least two-thirds of the depth of the body.  With two layers of corrugated board over a majority of the side and end panels, the style has great resistance to bulging when subjected to overhead weight.


Mailer - lightweight to save on postage. Perfect for shipping small, lightweight fragile items.​​ No tape, glue or staples needed.



Dimensions are given in the sequence of length, width, and depth.  The dimensions of a box are described based on the opening of an assembled box, which can be located on the top or the side, depending on how it is to be filled. The opening of a box is rectangular (it has two sets of parallel sides).  The longer of the two sides is considered its length, the shorter of the two sides is considered its widthThe side perpendicular to length and width is considered the depth of the box.  When supplying measurements always use the inside dimensions of the box!











The two most common types of corrugated cardboard are double wall and single wall.





Singlewall (SW) - The most common type of corrugation material used in boxes.  It consists of one medium (flute) glued between two sheets of linerboard.  It is available in a wide range of strengths.  For most customers, singlewall boxes provide the protection and durability required at an affordable price.  


Doublewall (DW) - Much more resistant to punctures or crushing when stacked. It consists of two mediums (flutes) glued between three sheets of linerboard.  Just like singlewall, it is also available in a variety of strengths.  Doublewall allows for heavier objects to be shipped and stacked and should be used when a stronger box or extra padding is needed.
