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.
