1. A packaging for a food product, comprising:
- a shaped main portion defining a space apt to receive the food product, which main portion is made at least predominantly of a fibrous cellulosic material and has;
a Taber stiffness 15°
ISO 2493, measured in a homogeneous section region, comprised in a range of about 20-1000 mN; and
permeability to water vapor, measured in controlled conditions of 38°
C. and 90% R.H., comprised in a range of about 30-1500 g/m2/24 h; and
a cover portion in a sheet form, which is made at least predominantly of a fibrous cellulosic material and has a permeability to water vapour about 100 g/m2/24 h in controlled conditions of 38°
C. and 90% R.H., in which the cover portion is sealingly connected to a peripheral rim of said shaped main portion,the packaging being so configured to be placed into an oven for heating or baking the food product received therein,wherein said shaped main portion is configured to obtain a temperature distribution along a vertical section of the food product having a variance comprised between about 0°
C. and 4°
C. for each centimeter of vertical section of the packaging.

Abstract
A packaging or wrapping for a food product, capable of resisting to high temperatures and of eliminating the overpressure generated by the water vapour inside the packaging due to temperature rise, without the same packaging having any aperture communicating its inside and the outside environment. The packaging is also adapted to restrain/reduce the emission of odor-generating substances that are generated during the heating or baking of the packaged food product, with respect to what occurs in the absence of a packaging, or with a packaging provided with apertures.
