Abstract
A physical properties calculating apparatus accepts inputs of material and thickness of an intermediate layer, accepts inputs of material and thickness of an outer layer, accepts inputs of material and thickness of an inner layer, accepts an input of outside air humidity, accepts an input of inside humidity, accepts an input of outside air temperature, calculates the moisture content of the intermediate layer by activating a sub-routine for calculating the moisture content of the intermediate layer based on the accepted various information and preset information, and calculates physical properties such as oxygen transmission rate of the intermediate layer based on the calculated moisture content of the intermediate layer and the accepted outside air temperature. It is possible to know the physical properties of the intermediate layer that forms a packaging material for packaging products to be packaged, such as foods, without actually measuring the physical properties.
