PLASTIC FILM FOR LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a plastic film used for laminate treated by glow discharge plasma at atmospheric pressure to obtain stable and strong adhesive force. SOLUTION: This plastic film for laminate is prepared by forming hydrophilic composition group increased in an element composition ratio (the sum total of Ols/Cls and Nls/Cls) to >=80%; in a nonpolar resin and >=50% in a polar resin than that of the original material constitution. The film expresses excellent adhesive force especially when it is treated with plasma in an air containing >=17.5 mmHg (at 20 deg.C dew point) absolute humidity of water.
