Mummification as a bondage practice involves restraining a living person's body in a non-damaging way by wrapping it head to toe, or neck to toe, in materials like saran wrap, clingfilm, cloth, bandages, rubber strips, duct tape, plaster bandages, bodybags, or straitjackets. The end result is a person completely immobilized and looking like an Egyptian mummy.

They may then either be left bound in a state of effective sensory deprivation for a period of time, or sensually stimulated in their state of bondage, before being released from their wrappings. Mummification is often used to enhance a feeling of total bodily helplessness, and incorporated with sensation play.
