This invention relates to a general packing of expanded graphite and the process for production thereof. The packing mainly includes vermiform laminae of expanded graphite and auxiliary materials, which is characterized by the embedment of the auxiliary materials into the vermiform graphite laminae, the bonding of the auxiliary materials to the vermiform graphite laminae with organic adhesives. The process for producing of the packing comprises the treatment of graphite with strong acid to produce interlaminar compound followed by transient expansion of treated graphite to become vermiform and the combination of vermiform graphite laminae with the auxiliary materials to produce packing. Wherein the above mentioned vermiform laminae of expanded graphite are bonded to the auxiliary materials with organic adhesives, and the auxiliary materials are embedded between the vermiform laminae of expanded graphite.
