[ What is claimed is:] [1.] A disposable elastic thermal back wrap comprising:a) at least one substantially rectangular piece of flexible material having a first end, a second end, a longitudinal axis running between said first end and said second end, a first edge and an opposing second edge running between said first end and said second end axial said longitudinal axis, one or more elastic portions between said first end and said second end wherein said elastic portion is stretchable along said longitudinal axis, and a length great enough to encircle a user's waist such that said first and second ends overlap;b) one or more thermal packs fixed within or to said piece of flexible material, which comprise a unified structure of at least one continuous layer, which consists essentially of a coextruded material having a first side of polypropylene and a second side of a low melt temperature copolymer wherein said continuous layer is semirigid at a temperature of about 25.degree. C. and substantially less rigid at a temperature of about 45.degree. C., and a plurality of individual heat cells spaced apart and fixed within or to said unified structure of said thermal pack; andc) a fastening system in order to hold said at least one piece of flexible material around said user's waist.
