A wrapping material is provided, which comprises two mono-axially stretched thermoplastic resin films, placed in such a manner that the stretching axes of the thermoplastic resin films cross each other at an angle of 45°to 90°, and an adhesive layer comprising an ethylene-ethyl acrylate copolymer resin sandwiched therebetween. This wrapping material has good physical strength and is suitable for use in the preparation of bags.
