Partial Shell for Packaging a Food Product, Packaging for a Food Product and Packaged Food Product

Abstract

The present invention relates to a food packaging comprising a first par-tial shell, which has a first depression and a first flange delimiting said first depression; a second partial shell, which has a second depression and a second flange delimiting said second depression; the first and second partial shells being coupled to each other via their flanges thus defining a cavity for holding food. The invention relates to novel types of packaging and partial shells. The first partial shell can be made of a material that is different from that of the second partial shell. The partial shell can have a window that consists of a first material which is different from a second material that forms at least one outer surface of the partial shell. The flange can have a first region that consists of a first material and a second region that consists of a second material.
