Abstract: The invention provides a heat recoverable article, like a heat shrinkable tubing, which is used for the joint or terminal arrangement of electric cables, wherein an inner layer is formed on the inner surface of the heat recoverable article comprising a polymer material. A resin composite containing ethylene alkyl(meth) acrylate carbon monoxide copolymer is used for the inner surface, to produce a heat shrinkable tubing having an outstanding adhesive property to adherents, without suffering from foaming during the manufacturing process since this inner layer has little hygroscopic property.
