To provide a new, unique and excellently versatile food product packaging material or the like capable of storing not only a food product with a little water content such as bread but also a food product with a large amount of water content and a liquid component for a long period at a high quality and subjecting the food product in the package directly to cooking.
SOLUTION: The food product packaging material is formed by molding a resin composition containing a thermoplastic resin and includes at least one moisture transmission control layer having a transition region having an increase in water vapor transmission amout W
VTR between a reference temperature TS (° C) and a temperature TS +10 (° C) of 2-100 times of an increase in water vapor transmission amout WVTR between a temperature TS -10 (° C) and the reference temperature TS (° C) in a plot chart of temperature (° C) - water capor transmission amount WVTR (g/(m2 h)) measured under a moisture condition of 60%RH based ON JIS L1099 A-2 method and having a water vapor transmission amount WVTR (g/m2 h) at a temperature less than the reference temperatue area of more than 0 and less than 50, and having a reference temperature Ts (° C) within the range of 0 to 100° C.COPYRIGHT: (C)2011 and JPO& INPIT
