Corrugated cardboard carton

Along with the standard FEFCO codes used to describe the shape or design of corrugated cartons and cardboard packing cases, there are a number of codes and symbols used to clearly define the design and construction of cardboard boxes, solid board or corrugated packaging.

Packaging design symbols

Each packaging drawing symbol equates to a specific computer code, defining cuts, scores and slits (perforations, inward and outward crease lines, etc), the type of manufacturer's joint (stitched, taped or glued), openings such as handholds (stripped, non-stripped) and importantly, flute direction.

Case dimensions

Packaging design layouts are always defined as if viewed from the inside of the case or box.

Measurements are always internal, taking the thickness of the cardboard used into consideration. This is especially important where exact external dimensions of the fibreboard carton must be achieved (for use with handling machinery or palletising)

The dimensions L, B, H are specified in each description of packaging case construction:

Length (L) x Breadth (B) x Height (H)

Length (L) = the longer dimension at the opening of the cardboard box
Breadth (B) = the shorter dimension at the opening of the cardboard box
Height (H) = the dimension from the top of the opening to the base of the carton

Note that for some models the numerical value of B can exceed the numerical value of L.

The specific layout of a carton drawing is defined based on the packaging manufacturer's joint used - e.g. a glued or stitched joint may extend from the shorter (B) or longer panel (L) - for example - the popular FEFCO 0201 slotted-type cardboard box:
