Packaging container made of biodegradable fiber material

Abstract

A packaging container made of biodegradable fiber material, comprising a shell-shaped base body with a bottom wall, a surrounding side wall and a peripheral rim, and a lid with a lid wall and a lid rim that extends complementary to the peripheral rim, wherein the base body and the lid are produced from a pulp containing a mixture of water and fresh fiber by means of a mold, wherein alkyl ketene dimers are added to the pulp as an additive, wherein the base body and the lid are dried and pressed after drying, and wherein the base body and the lid have a wall thickness of at least 3 mm. The fiber material packaging designed in this way is suitable for storing chilled food and provides both a strong insulating effect to prevent chilled food from warming up, as well as good resistance to moisture.
