Abstract
A fiber capsule and a method of compression molding a fiber-based packaging capsule, includes the steps: a raw capsule of a loosely bonded fiber mat is formed, which capsule has an opening; the raw capsule of the loosely bonded fiber mat is positioned on the inside of a substantially rigid mold having inner surfaces defining the molded outer surfaces of the fiber-based packaging capsule; the loosely bonded fiber mat is compression molded by the insertion of a pressurizable compression member through the opening. The pressing device is pressurized at a temperature of 150-250 degrees C.°. The compression molding takes 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.
