Abstract

The work aims to solve the problem that the inner carton is likely to be contaminated by the migration of ink and clarify the key detection indicators for controlling the quality of (Biaxially Oriented Polypropylene) BOPP cigarette packaging films. The related quality indicators affecting the ink permeability of BOPP cigarette packaging films such as chemical composition, thickness, water vapor permeability, oxygen permeability, contact angle of films and surface microstructure characteristics were systematically studied. The difference of the same detection indicators between ink-permeable BOPP cigarette packaging films and normal films was compared and analyzed. The results showed that the thickness, contact angle, water vapor permeability, oxygen permeability and other indicators had an important effect on the ink penetration resistance of BOPP cigarette packaging films, and the tiny holes in the films were the main reason for the ink to migrate through the films and contaminate the cartons. The contact angle, water vapor permeability and oxygen permeability of BOPP cigarette packaging films can be used as quality control indicators for the inspection of film manufacturers or the cigarette enterprises.
