Fiber-based packaging capsule and a method of press-forming the same

A method of compression molding a fiber-based packaging capsule, comprising the steps of:

• forming a raw capsule of a loosely bonded fibrous mat, which raw capsule has a moisture content between 3% and 20% and an opening,
• positioning the raw capsule of the loosely bonded fibrous mat on the inside of a substantially rigid mold having inner surfaces defining the compression-moulded outer surfaces of the fiber-based packaging capsule,
• compression molding the loosely bonded fibrous mat by inserting a pressure-reformable pressing member through said opening, the pressing member being formed of a plurality of unassembled parts including a first substantially pressure-applying part and a second substantially pressure-distributing part, at least said second part being at least partially reformable,
• pressurizing said pressing member at a temperature of 150-250 degrees C.°, and at a pressure of 100-5000 bar, wherein press forming takes place by reshaping the re-shapable pressing member and pressing the inside of the capsule against the inner surfaces of the rigid mold so that a solid cohesive fiber-based packaging capsule is obtained.
