PAPER CORE FOR PRESSURE SENSITIVE ADHESIVE FILM

摘要

PROBLEM TO BE SOLVED: To provide a paper core for a pressure sensitive adhesive film allowing to full use of the pressure sensitive adhesive film wound around the paper core for the pressure sensitive adhesive film to the last and easily recyclable as a paper resource after using it. SOLUTION: This paper core 1 for a pressure sensitive adhesive film is formed by winding a half glossed craft paper 3 as a face paper on a paper cylindrical base material formed of six layers of paper tube raw paper 2. A fluorine-based water repellent and oil repellent agents is adhered to the half glossed craft paper 3 at a degree to leave a clearance formed by entanglement of the paper fiber of the half glossed craft paper 3 (a surface of the face paper).
