ABSTRACT:
A carton blank may be formed from a first sheet of relatively rigid material and a second sheet of relatively flexible fluid impervious material. The second sheet of relatively flexible fluid impervious material may cover some but not other portions of the first sheet of relatively rigid material in order to facilitate gluing of the other portions of the first sheet of relatively rigid material when the carton blank is assembled into a carton.
