摘要： Laminating a stretched thin propylene-ethylene block copolymer layer onto a surface of a laminate film hving a biaxially oriented polypropylene layer and a polypropylene layer uniaxially oriented only in the width direction. The resulting film has improved hand-cutting properties and the surface accepts wiring or drawing and is especially advantageous for use as adhesive tape.
