Abstract
A fiber capsule and a method of compression molding a fiber-based packaging capsule, includes the steps: forming a raw capsule of a loosely bonded fiber mat, which capsule has an opening, positioning the raw capsule of the loosely bonded fiber mat on the inside of a substantially rigid mol having inner surfaces defining the molded outer surfaces of the fiber-based packaging capsule, compression molding the loosely bonded fiber mat by the insertion of a pressurizable compression member through the opening, and pressurizing the pressing device at a temperature of 150-250 degrees C.°, preferably 160-200 degrees C., and at a pressure of 100-5000 bar, preferably 300-1200 bar. The compression molding may take place by reshaping the reshaping pressing device and pressing the inside of the capsule against the inner surfaces of the rigid mold so that a cohesive fiber-based packaging capsule is obtained.
