Press‐formed paperboard food packages were heated and cooled to study
the humidity effect on the packages with a series of dimension
measurements. The empty packages in the form of trays were pre‐dried or
preconditioned before their packing with oatmeal, and heating humidity
of the packages was altered to find the optimal storing and heating
conditions for improving the dimensional stability of the trays. The
dimension measurement results showed aggravated dimensional stability of
the trays during the heating and cooling. Pre‐drying and low heating
humidity were observed to reduce the impact of the humidity effect on
the packages, and the humidity effect was linked to the material
moisture content change. The dry storing and heating humidity were
concluded to enhance the dimensional stability of the press‐formed
paperboard food packages. Use of the dry storing condition was found
necessary to mitigate the humidity effect in the heating and cooling of
the food packages.
