PROBLEM TO BE SOLVED: To provide a protective film with no separator which has good unwinding properties when it is unwound from a web. SOLUTION: The protective film with no separator has a base film and a pressure-sensitive adhesive layer formed on the surface of the base film using a pressure-sensitive adhesive layer-forming material which contains at least a pressure-sensitive adhesive. The pressure-sensitive adhesive layer has an adhesion in the range of 0.01-0.2 N/25 mm and a tack value in the range of 1-30 kN/m2. COPYRIGHT: (C)2009,JPO&INPIT
