Is a casket required if a body is cremated?

In a few states, a casket or alternative container is not required for cremation. In this case, the body may be wrapped in a fabric shroud prior to going into the cremation chamber. A regular casket is not specifically required to house the body going into the cremation chamber, but some form of alternative container is normally required, such as a simple box made of combustible materials. If a viewing is to be held prior to the cremation, it may be possible to rent a regular casket for the viewing and funeral, and then purchase the alternative container for the cremation process.
