Metallic bonding - Wikipedia

Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Internal Bonding - an overview | ScienceDirect Topics

Reynolds (1974) showed that dry strength additives have a more pronounced effect on internal bonding in paper at relatively low degrees of refining. With increased refining, pulp fibers effectively “make” their own bonding agents by increased hydration of fibers and increased fiber flexibility. Dry strength additives can help make bulky
