The essential function of packaging is to conserve the product that the package
contains. In the course of this conservation, packaging is affected by many
physical and chemical factors, the major one of which is moisture absorbed in
the cardboard. The package gets in a relationship with humidity in the air from
the time of its production up until its last user. It picks up most of the moisture it
has during the processes of offset printing and lamination.
This study examines both the procedures run before and after the manufacture of
packages produced in the packaging sector, and the interplay between the
package and the environments in which it is placed during these procedures. In
this research, the combination of 225 gram/mÇ cardboard, 112 gram/mÇ test-liner
and 125 gram/mÇ kraft-liner was used. The cardboard that were set to different
values of moisture and were brought to optimum condition in the conditioning
room were printed successively on the offset printing machine under the same
The printed cardboards were laminated after they were left for 24 hours in the
environment in which the lamination process was to be carried out. The
lamination was followed by the procedure of cutting and box-folding lines.
Afterwards such tests as ECT (Edge Crush Test), FCT (Flat Crush Test), BCT (Box Compression Test) were applied to the corrugated cardboards produced
after lamination. Finally, suggestions were offered as to which moisture values
the corrugated cardboards are more durable at during and after manufacturing.
