It is not uncommon during the reporting season for the results of smaller companies to go unnoticed, given the plethora of big firms that reveal their profits in the space of a few weeks.

Carton and packaging group Colorpak is one smaller company that has largely slipped under the radar. Its plight has not been helped by rising energy and materials prices that have created tough times for the industry. Indeed, the share price of sector heavyweight Amcor is hovering near its five-year low of $6.20.
