PURPOSE:To obtain the titled tape with high durability even under high- temperature and high-moisture conditions, suitable for corrosion-resisting applications for high-temperature pipings, by forming adhesive polyolefin layers on both sides of a heat-resistant polyolefin film followed by providing one of the sides with a specific adhesive layer. CONSTITUTION:Adhesive polyolefin layers 2 are formed on both sides of a heat-resistant polyolefin film 1, one of said layers 2 being provided with an adhesive layer 3 comprising an epoxy resin composition adhesive at normal temperature, thus obtaining the objective tape. Preferably, said polyolefin film 1 is made from PP (and/or) PE having a Vicat softening point >=120 deg.C; the layers 2 have a Vicat softening point >=100 deg.C; and said epoxy resin composition is curable at temperatures <=120 deg.C, comprising a (modified) epoxy resin and curing agent.
