Writing a corrugated box specification

Dimensions, ply, flute, grades and a performance test: five lines that prevent most box failures.

notes from our own lines

A box specification does not need to be long. It needs to be complete.

1. Inner dimensions

Length × width × height of the space inside, in millimetres, with the product orientation.

2. Ply and flute

3, 5 or 7 ply, and the flute profiles. More plies carry more weight.

3. Grades

GSM and burst factor of each liner and flute.

4. A performance test

Box compression (BCT) or burst strength, with conditioning. This is how you know the box works.

5. Print and markings

Colours, coverage, handling symbols and codes.

Send these with an enquiry and you will get a comparable quotation from any supplier.
