Abstract
A vinyl graphic marking film or label coated with a pressure sensitive acrylic adhesive designed to achieve high or permanent adhesion to polymeric low energy surfaces is disclosed. In addition to good adhesion to low energy surfaces, the graphic marking film or label may have microperforated or micro-rough edges which initiate tearing when removal is attempted. The article maintains flexibility and film strength for easy fabrication in graphic marking film or label manufacture.
